I will build or optimize your website backend, API and database


About this gig
Need your website or web app's backend working better not built from zero?
I specialize in fixing, optimizing, and extending existing backends: APIs, databases, and server-side logic. Whether something's broken, slow, or missing a feature, I dig into your codebase and solve it cleanly.
WHAT I CAN HELP WITH:
Debugging backend errors and broken API calls
Database queries, schema fixes, and performance optimization
Integrating third-party APIs (payment, data, auth, etc.)
Building REST APIs and backend logic for small/medium projects
Node.js, Express, JavaScript, React, Supabase, SQLite
MY STACK:
React, Node.js, Express, Supabase, SQLite, REST APIs, Cloudflare Workers.
HOW I WORK:
I ask for repo access or a clear problem description upfront, so I can give you an accurate timeline before we start. I write clean, commented code and test everything before delivery.
WHAT THIS GIG IS NOT FOR:
This service is for existing projects that need backend work not full websites built from scratch with design and frontend included. If that's what you need, feel free to message me and I'll let you know if I can help or point you in the right direction.
