ABOUT ME

I'm a Software Developer based in Mumbai. I build backend systems, real-time applications, and developer tools and I tend to think about them in terms of architecture and failure modes before I think about features.

The work I'm most proud of is work that scales without drama and that another engineer can pick up without a long explanation. That's the standard I hold my code to.
