I joined SuperTokens (YC S20) as a founding engineer in 2018, building the entire backend platform from scratch, distributed auth systems, multi-framework SDKs (6 Node.js frameworks), CI/CD pipelines, and SaaS infrastructure, helping grow it to 15K+ GitHub stars across 3 global AWS regions.

In parallel, I ran a Toptal freelance practice delivering TypeScript/Node.js cloud solutions at petabyte scale, achieving 20x upload latency improvements and 99%+ uptime for 15K DAUs.

I'm completing an MBA at UMD Smith (May 2026) in Product Management & Marketing as a Smith Fellow and Graduate Assistant. I'm equally comfortable writing architecture docs and product PRDs, and I'm open to both senior engineering and product management roles at startups and growth-stage companies.
