About

Hey there, I'm Priyansh Rastogi. I'm a Founding Engineer at Paygentic, where I'm building usage-based billing and payments infrastructure for AI agents. I did my Bachelors & Masters at IIIT Gwalior, and I've spent the last few years on systems where correctness under load is the real problem — payments, billing, and developer infrastructure, owned end-to-end.

Before Paygentic I was the first engineer at Sulu, a pay-as-you-go API marketplace that launched #2 on Product Hunt; built an internal developer platform at ShareChat; and earlier fell deep into open source — contributing to Bitcoin's Lightning Network at Lightning Labs and to mempool.space through Summer of Bitcoin. That open-source work opened doors to remote internships at US startups (Lightning Labs, CertiK) — which helped me pay my own way through college — and, more than anything, friends around the world.

These days I mostly live in Go and TypeScript, and think a little too much about idempotency, exactly-once semantics, and billing systems that never double-charge. Away from the keyboard I read a lot (a proper home library is a genuine life goal), meditate daily, and keep a healthy belief in cosmic timing alongside the logic. Always up for something interesting.
