I'm Santosh Kumar, a full-stack developer based in India. I focus on building complete products — from frontend to backend — and adding intelligent features where they make an impact.

My work spans full-stack development, scalable backend systems, and DevOps practices. I believe the best software isn't the most complex — it's the one that consistently ships value to users.

When I'm not building or deploying applications, you'll find me contributing to open-source and writing about full-stack development and DevOps.
