Software developer based in India. I build distributed and scalable systems — things that hold up under load, stay maintainable over time, and solve real problems cleanly.

I write code across the full stack, with a particular focus on backend systems and infrastructure. I think carefully about trade-offs: between simplicity and power, between moving fast and staying correct.

I communicate technical ideas clearly, work well in ambiguous problem spaces, and care about the craft of writing good software — not just working software.
