About Me

Solving complex problems elegantly

I'm a backend engineer. I work on systems that need to stay correct under load, survive edge cases, and remain maintainable for the team that inherits them. Currently building AI/ML infrastructure for Google Search; previously led the foundation of CRED Flash — the first money-making product line at CRED — and grew udaan's ads platform from ₹0.5M to ₹30M monthly revenue.

The work I find most satisfying sits at the intersection of distributed systems, data integrity, and product. If you're building something genuinely hard in that space — fintech, infra, or large-scale platforms — I'd love to hear about it.
