I build reliable backend systems and REST APIs for web applications using Node.js, Express.js, Python, and FastAPI.

Whether you need a new API, a backend feature, database integration, authentication, or fixes to an existing backend, I can help implement it and connect it with your frontend or other services.

REST API development

Node.js & Express.js backends

Python & FastAPI backends

I can work with an existing codebase or build a backend component from scratch based on your requirements.

My focus is on clean, maintainable APIs and practical backend solutions that fit your existing application.
