Hi, I'm Pawan — I Build Scalable Digital Experiences
I'm a full-stack software developer with 5+ years of experience designing and shipping production-grade web applications — from React interfaces to Node.js APIs and cloud infrastructure. I care about clean architecture, fast interfaces, and software that holds up in the real world.

Turning complex problems into reliable software
I'm Pawan Kumar, a full-stack developer who enjoys the entire lifecycle of a product — from the first architecture diagram to the metrics dashboard that tells you it's working. Over the last five years I've worked across fintech, SaaS and developer-tooling teams, usually as the person who connects the frontend, the backend and the infrastructure decisions between them.
My approach is simple: understand the problem before writing code, keep the system easy to change, and measure what actually matters. I'm equally comfortable pairing with designers on an interface or debugging a production incident at 2am — both are part of shipping software people rely on.

What people say about working with me
