Once registered, they’ll receive a unique ID and referral code, enabling them to invite others to buy policies and earn commission from each sale within their platform will feature a clean dashboard where users can track total earnings, referral progress, targets, and policy purchases. Admins (the company) will have control over user management, commission payouts, and policy ...

I’m building a fully-dynamic real-estate portal modelled on https://famproperties.com. The front-end will be delivered in either or Angular, powered by a Node.js API. Content, listings and user activity will be stored across both MySQL and MongoDB. Everything on the site—from neighbourhood pages to banner images—must be editable through a single admin panel.

Project Description: We are seeking a highly skilled and meticulous Manual QA Tester to perform comprehensive, human-driven testing on our application built with a modern tech stack: GCloud, MongoDB, Node.js (backend API), React (web frontend), and Flutter (iOS/Android mobile app). We need a dedicated individual to uncover bugs, test complex user flows, and provide invaluable human perspective on usability and functionality. The use of AI testing agents, automated frameworks, or any AI-generated test cases/scripts is strictly forbidden for this engagement. We need genuine, manual testing expertise.

I have two existing React Native apps that need a final round of polish before they go live. The current builds show a mix of UI/UX inconsistencies, a handful of functionality glitches, and some noticeable performance hiccups. I need all three categories cleaned up so the experience feels rock-solid. --------------------------------project details-------------------------------------- project is built on the MERN stack — the backend is developed using Node.js (with Express), the frontend is built with React.js, AWS Cloud storage, and the database is MongoDB. ---------------------------------------------------------------------------------------------- Once the fixes are in place, I want both apps thoroughly exercised on iOS and Android—from small phones to large tab...

I have a fully-working backend application running on a NodeJS + MongoDB stack, and I now need the entire codebase translated to PHP (preferably 8.x) with a MySQL database. The project is strictly about the server side; there is no front-end or mobile component involved. Your job is to replicate every current feature and API endpoint so that, once the switch is made, external clients will not notice any difference in responses, authentication flow, or performance. This includes redesigning the data layer: collections and document structures must become well-normalised MySQL tables, with any necessary migration scripts so I can move existing data over in one step. I will provide: • Access to the existing Git repository, including the API routes, models, and environment settings...

They get a dashboard showing their learning stats, badges, leaderboard position, and 4 avai...

My app is already deployed and the REST of the codebase runs fine on my Linux VPS. The missing piece is MongoDB: I still need the server configured from scratch and the existing dump imported so the application can finally read and write data locally on this machine. Here’s what I still need done: • Install and harden the latest stable MongoDB release on the VPS (Ubuntu/CentOS—whatever commands match the box). • Create the required admin and application users, set up authentication, and open only the necessary ports in the firewall. • Import the provided MongoDB dump so all collections and indexes come across intact. • Wire the connection string into my environment file, then restart the app and confirm that the API routes hit the database without e...

I need a streamlined productivity web app focused solely on task management. The core idea is to let users create, organize, and track tasks easily from any device. Because this isn’t an e-commerce platform or social network, every design and development choice should push speed, clarity, and simplicity. Key points I already know I’ll need: • Account creation and secure login (email or single-sign-on). • Intuitive dashboard where users can add, edit, reorder, and archive tasks. • Due dates, priorities, and simple status tags (e.g., “To Do / In Progress / Done”). • Responsive UI that works smoothly on desktop, tablet, and mobile. • Clean, modern look—nothing cluttered or gimmicky. Tech stack is flexible, though I’m com...

Here’s what I have in mind: • A clean Node.js + Express backend that handles all CRUD operations for business listings. • REST-based (or GraphQL if you prefer) endpoints so the front-end can be expanded later without rewrites. • A responsive database layer—MongoDB fits, but I’m open to your suggestion if you can justify it. • Basic admin tools to add, edit, and disable listings quickly. • Elastic search, text indexing, or any efficient search strategy that can surface results by name, category, or location i...

I am building a voice-first AI agent that can sit naturally across our CRM, chat and video modules and operate in real time on web and desktop. The stack is already defined—Node.js microservices, PostgreSQL for relational data, MongoDB for documents, and LiveKit for the low-latency audio/video layer—but I need an experienced developer who can turn that outline into a production-ready architecture and codebase. The agent itself must handle language understanding and generation, voice recognition and synthesis, plus smooth, real-time conversation management. Everything will be exposed through a clean API layer that my existing frontend can consume. Here’s what I expect to receive: • A container-ready microservice framework (NestJS or Express preferred) wired to Pos...

I am kicking off a new Java-based web application and need a developer who can guide the project from architecture through deployment. The core goal is to build a robust, secure, and scalable site; everything from the exact tech stack (Spring Boot, JSF, Struts, or another Java framework you favour) to the hosting setup is still flexible, so your recommendations will weigh heavily in our decisions. Because the business team works out of Goregaon, Mumbai, I’ll need someone who can join us on-site for key sprint meetings and hand-offs; day-to-day coding can be remote if that suits you better. Clear communication and clean, well-documented code are essential—this application will evolve quickly once the first release is live. Deliverables I expect: • Complete, runnable sourc...
