This is a full-time, two-year contract to design, build, and maintain a production-grade MERN application from the ground up. The entire stack—front end, back end, and database—will sit with one developer, so deep, hands-on experience across each layer is essential. Stack and tooling The current plan leans on Node.js for server logic, [login to view URL] for rendering and routing, and MongoDb for data persistence. Everything should be wired together with clean, testable JavaScript/TypeScript, Git-based workflows, and familiar DevOps practices (CI/CD, containerisation, cloud hosting of your choice). Daily responsibilities • Craft responsive, interactive UIs that feel native on web and mobile. • Implement rock-solid user authentication and role-based access. • Build REST/GraphQL endpoints and integrate them with the MongoDb data model. • Optimise queries, indexes, and backups to keep data fast and safe. • Ship iterative features in weekly sprints, write tests, review your own code, and document as you go. Contract terms • Duration: 24 months, 40 hrs/week (full-time). • Commitment: individual contributor only—no agencies or team hand-offs. • Experience: a minimum of three years in real-world MERN projects is non-negotiable; portfolio links or repos will be reviewed. Acceptance criteria 1. All features listed above meet functional specs and pass unit/integration tests. 2. UI achieves >90 % Lighthouse performance and responsive design scores. 3. Code merges cleanly into main branch with CI checks green. I will provide product requirements, UI wireframes, and access to existing assets; you provide the complete working codebase, tests, and deployment scripts. Continuous communication happens through Slack and weekly video stand-ups. If that sounds like the perfect long-term fit, prepare to dive straight into sprint one.

Hi Sir, We can provide a dedicated developer who will directly connect with you and work exclusively on your requirements throughout the engagement. He will follow your instructions, sprint priorities, coding standards, and communication process, with no team hand-offs or unnecessary layers between you and the developer. He can take ownership of the complete application lifecycle, from frontend development and backend architecture to database management, testing, deployment, and ongoing maintenance. You will have direct communication through Slack and weekly stand-ups, allowing you to review progress, provide feedback, and adjust priorities quickly. Development will follow a structured weekly sprint approach with clean, maintainable code, proper testing, documentation, and CI checks. Don’t worry about transparency—we will ensure clear communication, regular progress updates, and complete visibility into the development work. The developer will remain focused on your product and can start directly with Sprint One based on your requirements and wireframes. We’re interested in building this as a long-term partnership and supporting the application throughout the full two-year engagement. Best, Rahul

Hello, I have hands-on experience building and maintaining full-stack MERN applications with React, Node.js, MongoDB, REST APIs, authentication, and scalable production architectures. I’m comfortable taking ownership of the complete stack as an individual contributor over a long-term engagement. ? The core challenge in a two-year project is maintaining clean architecture and delivery speed as the application continuously grows. I focus on modular code, strong testing, and disciplined Git workflows from the first sprint. ✅ Frontend & backend: build responsive React interfaces, secure authentication and role-based access, plus clean REST/GraphQL APIs using Node.js and TypeScript. ✅ Database & reliability: design efficient MongoDB schemas, indexes, query optimization, backups, unit/integration tests, and CI/CD pipelines. ✅ Long-term development: deliver features in weekly sprints with documented code, code reviews, containerized deployments, and consistent performance optimization targeting 90+ Lighthouse scores. I can commit as an individual developer and take full technical ownership across frontend, backend, database, testing, and deployment throughout the engagement. I’d be happy to discuss the first sprint, product architecture, and the technical priorities you want established from day one. Best regards, Michel

This looks like a great long-term role. I have been building MERN apps for over four years and I am used to owning the whole stack on my own. I can handle the front end, the API layer, and the database without any hand-offs. Authentication, responsive design, performance, and deployment are all things I do regularly. Similar projects I have built: SaaS Dashboard: Full MERN app with role-based access and 50,000 daily users. I designed the MongoDB schema, built the APIs, and set up the CI/CD pipeline. Online Course Platform: Node, React, and MongoDB. I handled user login, payment flow, and search. Wrote tests and deployed with Docker. Healthcare Data Tool: Real-time charts and reports using GraphQL. I optimised slow queries and set up automatic database backups. I am comfortable with weekly sprints, Slack, and video stand-ups. Happy to jump straight in with your wireframes and requirements. When can we have a chat on it to discuss further about it.

one line in your brief is the one worth talking about: review your own code. i would not pretend that works. self-review catches typos and misses decisions, and across twenty-four months it is the decisions that compound. so i would replace it with the two things that do work without a second salary. tests that fail loudly when behaviour changes, and a short written record of why each significant choice was made, written at the time rather than reconstructed a year later. that leads to the real risk in a two-year single-developer build, which is not that the code turns out bad. it is that by month eighteen only one person can safely change it, and you are locked to whoever that is. i work the other way round: the repository, the setup and the reasoning stay clear enough that another developer could pick it up cold. that protects you if i am ill, and it protects you from me. on the data layer, the usual mongo failure is designing it like a relational database and bolting indexes on afterwards. indexes follow access patterns, so i want the main read paths named before the schema hardens, not after the collections are large. on auth i would not hand-roll it. role-based access on a proven library, with the roles defined in one place instead of scattered through route handlers. i work south african hours, utc plus two, which covers the bulk of your working day. what is the application actually for, and is any of it built already?
