Backend & APIs
Node.js Backend and API Developer
Secure, well-structured APIs and data models that keep your product reliable as usage grows.
How I can help
A dependable backend is what keeps your product fast and secure as more people use it. I build Node.js backends with clean, documented APIs and well-designed databases.
Whether you need a new backend for a web or mobile app, integrations with payment and third-party services, or help scaling an existing system, I focus on structure that your future team can understand and extend.

Frequently asked questions
Have a different question? Ask me directly.
MongoDB or PostgreSQL: which should I choose?
It depends on your data. PostgreSQL is ideal for structured, relational data and reporting, while MongoDB suits flexible, document-shaped data. I recommend the right fit during discovery.
Can you work on an existing backend?
Yes. I can review, refactor and extend existing Node.js systems, improve performance, and add tests so changes are safer.
Do you document the APIs?
Yes. Every API comes with documentation so your frontend, mobile or partner teams can integrate without guesswork.
