    My PHP 8.x application has picked up a fair amount of dead weight—unused files, legacy snippets, and the odd warning that only shows up in the logs. I need a developer who can open the hood, keep what truly matters, and scrap the rest while making sure everything that stays runs flawlessly. Here’s what I’m asking you to do: • Read the entire codebase, identify the core file(s), and strip away anything that isn’t required. • Hunt down every notice, warning, or fatal error and resolve it so the script executes cleanly on PHP 8.x with error reporting turned up. • Where you see obvious performance wins—query consolidation, tighter loops, lighter includes—go ahead and tune them. • I’m not entirely sure which smaller features ...

    The goal is to craft a complete web application from the ground up, pairing a React.js front end with a Node.js back end and shipping a functional MVP within a month. I already know I want React for the client interface, so the build should follow best-practice component architecture, modern hooks, and a clean, responsive layout. On the server side, Node.js (Express preferred) will power a RESTful API, handle authentication, and connect to a persistent data store—MongoDB or PostgreSQL, whichever you feel best suits the use case. To keep expectations crystal clear, here are the concrete deliverables: • Git repo initialized with meaningful commits, README, and .env sample • React UI coded, styled, and wired to the API (state management via hooks or Redux) • Node.js...

    I already have a live Flutter app and an active AdMob account. I now want Google AdMob Native (In-Feed) ads woven into my main listing feed, very similar to the way OLX sprinkles promotions between items. Here’s the flow I’m aiming for: after every five feed items a native ad should appear, matching the app’s current look and feel so users experience it as part of the content rather than a banner. I do not yet have the specific Native ad-unit ID, so I’ll need you to walk me through creating it in the AdMob console and wiring it up in code. The project is straightforward: plug the Google Mobile Ads SDK into my existing Flutter codebase (Dart), build a widget that pulls and renders the Native ad, place it in the list adapter, then verify that test ads show up reli...

The stack is already set—React on the front end, Node.js (with Express or a comparable framework) driving the server side—so you should feel completely at home with modern JavaScript, component-based UI design, RESTful (or GraphQL) APIs, and the usual DevOps steps that get everything running smoothly in the cloud. The exact product domain is still flexible; what matters most is clean architecture, clear code, and a smooth hand-off.

Core objective The user authentication flow needs to feel seamless on desktop and mobile: sign-up, email verification, password reset, and role-based access for future member-only pages. Security best practices such as salted hashing, rate-limiting on login attempts, and HTTPS enforcement are non-negotiable. Beyond that, the look and feel should be straightforward: a home page, an about section, and an...

    My OpenCart store is currently unable to complete orders whenever customers choose at checkout. The payment window opens and the customer submits their card details, but the process never reaches the final “order confirmed” stage in OpenCart, so no order is recorded in the back-office and no confirmation email is sent. Other gateways behave normally, so the problem appears isolated to the integration. I need someone who knows OpenCart’s checkout workflow inside out and is comfortable digging into the extension, transaction logs, and any JavaScript or server-side conflicts that might be interrupting the callback. Your goal is simple: identify the failure point, apply the fix, and prove that an order can move cleanly from payment to confirmation every time. Deliverable...

    The site is already live and stable; I simply need a capable developer to take it from “almost there” to fully launch-ready. The previous programmer had to step away for health reasons, so I’m looking for someone who can quickly audit the existing codebase, identify whatever loose ends remain, and push the project over the finish line. Key points you should know: • Current progress sits at roughly 95 %. • It must look and work flawlessly on both Desktop and Mobile; tablet support is a welcome bonus but not mandatory. • The core stack, repo access, hosting credentials, and a concise hand-over note from the earlier developer will be provided on day one. What I expect from you: 1. A brief review summarising what’s left and how you plan to han...

    I want the running total revenue from my Shopify store to show on a Wi-Fi-enabled physical counter that sits on my desk. The job is to build the small bridge between Shopify’s JSON API and the hardware. Here’s what I already have and what I need from you: • Data source – Shopify: I only care about the store’s Total revenue figure. A lightweight call to the REST Admin API (or GraphQL if you prefer) is enough. I will supply the private-app credentials. • Destination – Hardware counter: It connects over Wi-Fi. You can target it with plain HTTP, WebSocket, or MQTT; whichever is simplest to flash onto a common ESP8266/ESP32 controller. I can handle the flashing if you give me the compiled binary or the Arduino/PlatformIO project. • Service layer:...

    I need an experienced WordPress developer who can drop straight into my current theme and extend it with database-driven pages. Every new template has to match the site’s existing typography, colours and spacing, so a good eye for detail is essential. You’ll connect the pages to our MySQL data—Custom Post Types or ACF are fine, as long as the front end stays lightweight. A second priority is cleaning up legacy links. I want meta-refresh redirects put in place so users and tracking scripts are seamlessly forwarded from old campaign URLs to the new destinations. While you build, I also expect solid on-page SEO: title tags, headings, schema, image alt text and internal links all aligned with the keyword plan I’ll provide. Whether you prefer Yoast or RankMath, make su...

    Modern Service Landing Page Build

    The layout, color scheme, and all German text are complete. I now need a one-page service website that matches the mock-ups and looks modern and elegant on all devices. Your task is to translate the provided design files into clean, responsive code (CMS WordPress block template) and deliver a page that can be used directly without further adjustments. Smooth scrolling, subtle hover effects, and fast loading times are important to me; otherwise, there will be no changes to the existing design. I will provide you with the assets, fonts, and text immediately after the project begins and am available for prompt feedback so we can complete the project efficiently. The landing page does not require integration with an email or payment system. Please share one or two examples of similar servic...

    I have a working file-transfer script that already handles all the send/receive logic; now I need it wrapped into a polished desktop application that installs cleanly on Windows, Linux and macOS. After installation, the embedded sync-engine must run automatically at regular, short intervals—every few minutes—without user intervention, quietly polling our remote server and pushing or pulling any file changes it detects. What I still need built is the installable package itself along with a lightweight settings interface that supports both light and dark themes. The GUI only has to let users confirm the target folder and, if they wish, pause or resume syncing, so the design can stay minimal yet visually impressive. Under the hood the sync routine should launch on startup (servic...
