About Me

I am Ritesh Kumar — a pragmatic engineer who focuses on building scalable backend services and delightful frontends. With 3 years of experience primarily in Node.js and 4 years in Java, I have shipped mobile apps and web platforms that include payments, notifications and integrations with third-party services.

If you need a developer who can own features end-to-end — from system design to deployment — I can help.
