I’m looking to build a long-term collaboration with someone who can discuss architecture and trade-offs in clear, native-level English while turning ideas into production-ready web applications. The stack you’ll step into is centred on React.js for the front end and a mix of JavaScript/TypeScript services alongside Python micro-services on the back end. Day to day you’ll pick up features from our roadmap, shape the UX with React components, wire them to REST- or GraphQL-based endpoints, and help keep our automated tests green. I’ll count on you to suggest best practices, refactor when technical debt appears, and push code through pull-request review to staging and live. Because this is an ongoing partnership rather than a one-off gig, reliability and proactive communication matter as much as solid coding. If you’re comfortable pair-programming over video, writing concise documentation, and giving thoughtful estimates, you’ll fit right in. Key deliverables for each sprint: • Fully functional React components and related hooks • Corresponding server-side logic in JavaScript/TypeScript or Python • Updated unit/integration tests and CI-passing builds • Brief change log and inline documentation If you’re eager to grow a product with me over time and have the skills above, let’s talk.

Hello, If you’re scaling a product, the bottleneck usually isn’t features, it’s architecture. I help teams ship fast without accumulating hidden tech debt by building type-safe React systems and resilient Python/Node services that integrate cleanly with CI/CD. I own features end-to-end, from composable hooks and predictable state to well-typed REST/GraphQL APIs with strong validation, caching, and observability. I also step in early on service boundaries, schema design, and performance tuning before they become costly problems. Expect clean PRs, solid test coverage, and thoughtful trade-offs (monolith vs microservices, speed vs complexity). I am reliable, responsive, and focused on long-term results. Happy to hop on a quick call to discuss how we can work together. Best, Niral
