Full-Stack Software & High-Concurrency Systems.

Harsh Dabas - Software Engineer

Greetings, I'm Harsh Dabas. I am a Software Engineer who builds complete products and resilient infrastructure. I use TypeScript, React and Node.js to deliver scalable user interfaces and integrate AI features. For deep backend bottlenecks and extreme concurrency, I architect high-performance engines in Go. My approach is simple: ship features efficiently, locate the bottlenecks and rebuild the critical paths until they hold under peak traffic.
