01. About Me

Hello! I'm Naveen — a backend engineer based in Hyderabad, India, who genuinely enjoys turning complex business problems into clean, scalable Node.js services.

My journey started in 2018 building MEAN-stack applications, and over the last 7+ years I've gravitated deeper into distributed systems, API design, and the cloud infrastructure that keeps them alive in production.

Today I lead backend development at Valuefy Technologies, shipping wealth-management and mutual-funds platforms for HDFC Bank and IndusInd Bank that serve millions of customers and process crores of records.

Here are a few technologies I work with daily:
