I am preparing to release the final payment to my current development team and want absolute confidence that the code base is clean, secure, and free of anything that could be used against me later. Your mission is to perform an independent, end-to-end audit that zeroes in on code quality and security, followed by a roadmap for reliable, Texas-based support. Scope of the audit • Code review and best practices – confirm style consistency, proper version control use, and absence of hard-coded secrets or hidden backdoors. • Security vulnerabilities – static and dynamic analysis, penetration testing where appropriate, and a clear risk matrix that prioritizes critical fixes. • Performance health – benchmark speed and efficiency, stress-test error handling...
I have attached a detailed scope of work that outlines everything I need. Your task right now is simple: study the document closely and come back to me with one clear, all-inclusive lump-sum price in USD. Alongside that figure, I would like you to outline the following so I can compare proposals easily: • A brief breakdown of major cost drivers (so I understand where the money goes). • The timeline you can commit to from kickoff through final hand-over. • Any key assumptions or exclusions that affect your price. If something in the scope is unclear, flag it early so we can resolve it before you finalise your number. Once we agree on the total, I expect milestones to follow the same structure we discuss in your quotation. Please review the attachment carefully...
I’m facing a persistent technical problem that’s blocking progress on my current project. The exact details involve proprietary code and configuration, so I’ll share full access, logs, and replication steps once we start. Your task is to diagnose the root cause, implement a clean, verifiable fix, and document what you changed so I can maintain it going forward. A concise post-mortem explaining why the issue occurred is also important to me. The engagement is complete when: • The problem no longer appears in my staging environment. • Your notes let me reproduce the fix on production without guesswork. If you’re comfortable jumping into an existing codebase, tracing bugs, and delivering a solid solution quickly, I’m ready to get started ri...

Test a Windows Desktop Application and Report Stability / Feature Issues Summary I am looking for 1 Windows user to test a Windows desktop application and provide clear feedback about the overall experience, stability, and functionality of the software. This is not SEO, promotion, backlink building, social sharing, or an app review job. The goal is to test the application like a real user and report whether features work correctly, if anything crashes, freezes, behaves unexpectedly, or feels confusing. What you will do: 1. Download and run the provided Windows application. 2. Test the main features of the project. 3. Check whether the application runs smoothly and stably. 4. Report any bugs, crashes, errors, freezes, or unexpected behavior. 5. Check if certain features are missing, bro...
I’m down to the very last hurdle on a public Shopify dropshipping app I’ve built: the embedded-app verification fails whenever an order-sync call hits our backend. The request reaches us, but HMAC validation throws an “Authentication error.” Here’s what I know so far: • The failure appears only while syncing orders from Shopify Admin—install flow and every other endpoint work fine. • I’ve triple-checked the shared secret, stepped through the signing logic, and hammered it with sample payloads, so the usual suspects look good. What I need is an expert who has already wrestled with Shopify’s embedded-app security model and can pinpoint why the computed digest diverges, update the signing/verification code, and prove that eve...
I need a complete hospital management platform that covers patient registration and profile management, real-time appointment scheduling, and a robust billing & invoicing module tied to our existing accounting flow. The application must recognise multiple user roles—doctors, nurses, front-desk staff, finance officers, and system admins—so each team member only sees the screens and actions relevant to their duties. A fully integrated Electronic Medical Records component is essential. Clinicians should be able to capture, edit, and view patient histories, medications, lab results, and imaging reports directly from within the same interface without having to switch systems. Access to sensitive EMR data must follow role-based permissions and standard audit logging. Key expect...
I’m assembling an educational, step-by-step guide that shows advanced Python learners how to draw a perfect heart with the turtle graphics library. The finished piece should not only walk through each turtle command but also explain the underlying math so readers understand why every turn, radius, or fill action creates the final shape. Here’s what I need from you: • A well-structured Python script that relies solely on turtle, cleanly commented and broken into logical steps. • A narrative tutorial (Markdown or Word) that introduces the goal, explains each code block, and highlights advanced tips—optimizing drawing speed, customizing colours, and parameterising the heart size. • At least one set of visuals: incremental screenshots or an animated GIF g...
I want you to make NMS software Network Monitoring system
I want a clean, well-documented Python layer that talks directly to my existing FileMaker solution. The goal is to let my scripts read, write, and update records that contain a mix of text, numbers, and other field types without disrupting daily use of the database. This is revamping an existing connection between law firm authorized user and external web database. Connection method is flexible—FileMaker Data API, XML Gateway, or ODBC are all acceptable as long as the final code is reliable, secure, and keeps the FileMaker file schema untouched. Because several people will eventually call these functions, I also need a simple role system inside the Python code (e.g., admin, editor, viewer) that maps to FileMaker credentials and cleanly blocks unauthorized actions. Please deliver: ...
I need a cross-platform Flutter application that runs smoothly on both iOS and Android. The core of the project is a full-featured e-commerce experience built from the ground up. Key functionality required: • Product catalog with search and category filters • Shopping cart that updates quantities and totals in real time • Secure payment gateway integration (Stripe or similar) UI should follow current Material 3 guidelines, feel crisp, and load quickly even on older devices. State management with Provider or Riverpod is preferred, but I’m open to Bloc if you make a strong case. Clean, well-commented code and clear folder structure are essential because I will hand this to an in-house team for future updates. Acceptance criteria: 1. Both iOS and Android builds com...

Every Monday our pull-requests pile up and I need a battle-tested iOS Tech Lead—someone who has spent at least a decade deep in both Swift and Objective-C—to give them a sharp, independent review. The scope is straightforward: open the Git repository, step through the outstanding PRs, and leave clear, actionable comments that raise our bar for code quality and standards, tighten performance, and surface any security weaknesses you detect. No mentoring sessions or team training are required; the goal is strictly to refine code, flag problems, and suggest solid fixes before we merge. Typical Monday workflow • Clone or pull the latest branch updates from Git • Review each PR line-by-line, checking architecture choices, memory management, threading, and API usage ...
I’m looking for an experienced Laravel developer to jump into my existing codebase and implement several new features that will extend current functionality without disrupting live users.

I’m building an immersive rehabilitation platform that challenges patients cognitively while simultaneously guiding targeted motor exercises. The goal is to keep therapy engaging, data-driven, and clinically meaningful inside a standalone VR headset (ideally Quest 2/3, though I’m open to PC-tethered solutions if you can justify the trade-offs). Cognitive focus • Memory • Attention • Problem-solving • Executive functions Motor focus • Fine motor control • Gross motor movements • Hand–eye coordination • Gait and balance training Here’s what I need from you: an end-to-end Unity or Unreal project with therapy “mini-game” scenes that adapt difficulty in real time, record kinematic data, and export...

I’m moving our production e-commerce site from a brittle monolith to a fully-type-safe stack based on v14, NestJS, PostgreSQL, , and Stripe. The immediate, highest-priority task is a thorough refactor of the existing legacy codebase so we can eliminate the high server response times that are slowing checkout and catalogue pages. Once the worst bottlenecks are gone, the roadmap continues with clean REST/GraphQL APIs and a hardened Stripe integration, all built with TDD and modern best practices in mind. You’ll be working inside a GitHub repo with CI already wired for Jest and ESLint; every merge must keep tests green and Lighthouse scores healthy. Key context you should know: • Current pain point: performance inefficiencies, specifically high server response times...

I run a software company that handles a steady stream of customer enquiries every day, and I need a reliable hand to keep our users happy. Your core task will be installing and troubleshooting our applications on both Windows and macOS systems, then replying to customers by email with clear, friendly updates that match the simple response templates I provide. Because many of our users are non-technical, you will occasionally jump into a remote-access session (any standard tool you are comfortable with is fine) to walk them through the fix or complete the install for them. A fast typing speed and good written English are essential so every message feels personal yet professional. Work rhythm • 10 hours daily, 30 days a month • Initial commitment of at least one year, renew...
I have an existing Flutter application running on both Android and iOS with Laravel backend that now needs a complete quality sweep. The first priority is to put every screen and flow under a microscope—especially the Login/Register process, the full payment pathway, and user-profile management—so I know exactly where things break, lag, or confuse users. Also, there is an error with AI api configuration. Once a clear, reproducible bug list is in hand, the same engagement rolls straight into fixing those flaws in the codebase. While doing so, please keep an eye on navigation flow and overall user interaction; if small tweaks there can make the app feel smoother, include them in your pull requests. Visual design changes aren’t required this round, but I welcome concise sug...
EJB3 ebook Tutoring Needed. Ebook is already with me.
I need a Windows-based baccarat application that can sit open next to a live or online table and tell me exactly what to do next. The interface should embrace a clean, modern look, with six strategy panels visible at all times. Each panel must run its own profit-and-loss tally, independent of the others, and display a small live graph so I can spot streaks at a glance. Core workflow • I enter the starting bankroll and, via a simple input field, the stake I want to use for the very first hand. • While I play, the program records my results and instantly tells me two things for the next round: 1. the stake size required to recover any losses or lock in profit for that strategy, and 2. whether to bet Player, Banker, or Tie (I will provide the exact betting logic for eac...
From Pakistan or India we need Python Developer for long term and at low budget. I have a brand-new, web-based project that needs to be coded in Python from the ground up. The scope is intentionally lean so a junior-level developer can comfortably handle it while still touching the core pieces of a modern web app. The stack is flexible: Django or Flask are both fine, as long as the final codebase is clean, documented, and easy for me to pick up later. A lightweight front-end (simple HTML/CSS or any minimal JS you prefer) is all that’s required; the emphasis is on solid back-end structure.
I need the “Dynamic Pricing / Dynamic Price Range” plugin on my WooCommerce store to ignore the regular price and calculate all discounts from the Wholesale Suite price whenever a customer is logged in as a wholesale user. Right now wholesale shoppers see no discount at all because the plugin still references the regular price. My flash sales are usually fixed-amount discounts, so the adjusted logic must handle that scenario first, though it should remain compatible with any other rule types already supported by the plugin. The work involves: • Rewriting the plugin’s price-retrieval logic so every tier, cart rule, schedule, and shortcode tied to dynamic pricing pulls the wholesale price returned by Wholesale Suite. • Maintaining full compatibility with e...
I need production-ready configs for both OpenBullet and SilverBullet that will be used primarily for automated testing scenarios. You’ve worked with these frameworks before, so you already understand how to chain requests, handle captchas, parse dynamic tokens and build stable key-check logic without false positives. The project covers: • Building one or more configs tailored to my target endpoint (details shared in chat). • Optimising for speed, reliability and low ban-rate, with proper error handling. • Delivering the finished .opk/.svb files along with a short README that explains required inputs, custom wordlists or proxies and any modules/plugins used. Acceptance will be based on: 1. Successful test runs on my side that reproduce the expected output. ...
I need a straightforward way to open an existing PDF, click straight into any line, and change the wording without touching the layout. The essential capability is modifying existing text; adding or deleting text blocks isn’t required, and I don’t need image manipulation or form-filling tools. Because many of my documents carry unique branding, the solution must recognise and preserve embedded custom fonts exactly as they appear in the original file. Once the edits are saved, the PDF should keep the same look—no font substitutions, spacing shifts, or re-flow. Deliverable • A working PDF editor (desktop app, script, or web tool—whichever you feel suits the task best) that: – Opens any supplied PDF. – Allows inline modification of exis...
We are looking to develop a custom automation tool for the Telangana Sand Booking portal ().

I’m running a ZKtec Biotime deployment that has begun throwing software errors I can’t pin down. My immediate goal is to get the system fully stable again and understand the root cause of the bugs, whether they stem from the database, the Biotime service, or an interaction with the operating system. Here’s what I need from you: • Diagnose the recurring software errors in my current Biotime installation. • Apply fixes or patches to remove the bugs and restore normal operation. • Document what went wrong, how you resolved it, and any preventive steps I should take. Access will be provided to the server via remote session at a mutually convenient time. I’ll also share the exact error logs I’m seeing so you can start investigating right away....
I’m ready to commission a brand-new Android application focused on “Writting.” This is a straight mobile app development assignment: a clean, distraction-free space where users can draft, edit, and store text directly on their phones. Scope • Build the app from scratch in Kotlin or Java using Android Studio. • Design an intuitive Material-style interface that scales smoothly across screen sizes. • Core features: create, edit, and save text; basic formatting; share or export files. • Deliver well-commented source code plus an installable AAB/APK that passes Play Console pre-launch checks. Nice-to-haves (let me know what’s feasible) • Markdown support. • Dark/light theme toggle. • Autosave with simple version history....

I’m running an ArduRover platform on top of a fully custom-built mission planner and would like an experienced hand to refine two specific areas: route optimization and waypoint management. The core code already communicates with the vehicle via MAVLink, but the logic that selects, orders, and dynamically adjusts waypoints is still basic. Here’s what I need from you: • Analyse the present planner codebase (Python and C++ modules) and map out its current decision-making flow. • Design and implement smarter route-selection algorithms that minimise distance, energy use, and turning radius while respecting geo-fences. • Build an intuitive waypoint-handling layer so I can insert, reorder, or delete waypoints on the fly and have those changes propagate safely ...
Our product runs on a custom embedded system and it now needs a dedicated firmware module that can handle all UART-based communication. I already have the hardware schematic and register map; what is missing is production-ready code that initializes the peripherals, manages interrupts, frames the data, and exposes a clean API the application layer can call. Here is what I need from you: • Develop clean, well-documented firmware in C or C++ that brings up the MCU, configures the UART peripheral, and implements reliable transmit/receive routines (including error handling and buffering). • Follow our existing coding conventions and keep the footprint small so power consumption stays within spec; DMA or low-power sleep modes are welcome where appropriate. • Provide a conci...

I need a full-featured software package that lets me run every gaming PC in my café from a single reception machine. On the admin panel I must be able to manage customer play time in real-time, handle all billing and payment operations, and pull clear daily reports at closing. Each client PC should run a lightweight app that automatically locks or unlocks when purchased time expires, lets staff start, stop or pause a session on demand, and shows the player an up-to-date wallet/recharge balance. The whole setup will sit on our local LAN so it has to remain lightning-fast and independent of any external connection. Three access tiers are required: • Admin – full configuration, pricing and reporting • Staff – front-desk controls without deep settings acc...
I’m consolidating a group of Web, mobile, and desktop apps that all authenticate through the OpenClaw stack, and I need one coherent Role-Based Access Control configuration to govern them. The goal is to define every permission once, apply it consistently across each application, and have automatic notifications fire whenever roles or privileges change. Here’s what I want to come out of this engagement: • A clean, documented RBAC schema in OpenClaw that maps roles to fine-grained permissions and can be consumed by every client app. • Integration code (middleware or service hooks) that makes each application respect the new role definitions. • A notification workflow—email and push first, with SMS kept in mind—that broadcasts events such as role ...
