What I'm looking for

I seek an SDE-2/backend role on fast-moving product teams where I can deepen system design expertise, solve high-scale backend problems, and mentor engineers.

I am a backend engineer with three years of experience building and scaling Django APIs and leading core system design at a YCombinator-backed startup. I specialize in backend architecture, RESTful APIs, performance optimization, and maintainable codebases.

At OneFin I led an eight-engineer backend squad while remaining hands-on, scaling a payments platform to 90,000+ monthly transactions and 100,000+ monthly API requests, achieving 99.9% uptime and sub-200ms p95 latency. I drove enterprise integrations, automated loan-book workflows that freed 40+ ops hours per month, and helped double AUM from ₹500Cr to ₹1,000Cr in 18 months.

I built internal frameworks for AI agents, developed high-traffic REST APIs, and mentored junior engineers to improve code quality and team performance. I am seeking an SDE-2 role where I can deepen system design work and contribute to fast-moving product teams solving complex backend problems at scale.
