Hi, Your project is exactly the kind of long-term collaboration I look for. Rather than building from scratch, I enjoy understanding existing codebases, improving architecture, fixing issues, and adding new functionality while keeping production stable. To answer your questions: Yes, I've worked extensively with React and Supabase-based applications. Absolutely. A large part of my work involves extending and debugging existing production systems. Yes, I've worked with Supabase Auth, Database, Storage, Row Level Security (RLS), Realtime features, and API integrations. Yes, I'm comfortable deploying and maintaining applications hosted on Hostinger. I never modify production directly. I'll first review the codebase, work in a separate development branch or staging environment, thoroughly test all changes, obtain your approval, and then deploy safely. My approach is to first understand the project architecture, identify dependencies, review the requested changes, share an implementation plan with estimated effort, complete development, perform comprehensive testing, document all changes, and finally assist with deployment. One quick question: Do you already have a staging environment or Git-based deployment workflow in place, or would you like me to help establish one before making production changes? I'm available to start immediately and would be happy to support your project on an ongoing basis. Thanks, Rajesh

Hi, your "React.js + Supabase Developer Needed for Website Modifications & Enhancements" project is right in my wheelhouse. I develop modern JavaScript apps end to end — React/Vue/Next on the front and Node/Express on the back, in TypeScript where it helps. Working with javascript, web security, testing / qa, html, node.js, web hosting, react.js, payment gateway integration, website development, supabase, I focus on responsive, fast UIs, clean component structure, and reliable APIs — no page-builder shortcuts. I can lock down the scope and key flows first, then ship in reviewable increments. Can we hop on a quick chat to align on your requirements? ⭐ 5.0/5 from a recent client: "Very Professional and On time delivery of the project" Final timeline and cost will be confirmed in chat after a complete understanding and documentation of the project expectations in detail.

Hi, Working on an existing React.js + Supabase application starts with understanding how the current system works before making any changes. That approach helps avoid unexpected issues and keeps the project stable as new features and fixes are introduced. I'd begin by reviewing the codebase, React components, Supabase structure, and existing workflows before recommending any changes. No updates would be made directly to the live website—I prefer working in a development or staging environment, testing every change thoroughly, documenting the updates, and deploying only after your approval. I can work with existing React.js projects, debug and extend current functionality, handle Supabase features such as Auth, database tables, Storage, and related integrations, and support deployments on Hostinger. After reviewing the project, I'll provide a clear summary of the required changes, any potential risks, and the recommended implementation plan before development begins. A couple of quick questions: * Do you already have a staging environment, or should we set one up? * Which issues or enhancements would you like to prioritize first? If you can share the repository and the initial list of changes, I'll review everything, recommend the best approach, and provide a realistic timeline before we get started. I'm happy to support the project long term as new features and improvements are needed. Lets discuss on chat. Regards Abhishek
