I write
code.

I’m Saurav, a final-year student from Pune. I mostly write backend code in TypeScript and NestJS, and I’m learning Go right now. I’m also building valve, an outbound rate limiter for Node.js with shared API budgets and per-tenant or per-recipient limits.

§06 about me

About

I like understanding how the things I use actually work, and a few of my projects started that way. I rooted my projector so I could run my own server on it. And while building a WhatsApp API integration into a client’s CRM, I kept running into outbound rate limits, so I built valve.

Most of my work is backend TypeScript with NestJS, Postgres, Redis and job queues. I’m learning Go now, and I’ve started trying out Rust.

I learned the most when a more experienced developer reviewed my code every day. So I’m looking for an internship on a small team where I can work on real features and get regular feedback on my code.

the longer story
that’s me

§07 get in touch

Hiring an intern?

I’m looking for a software engineering internship. Email me with a bit about your team and what I’d be working on. If you just have a question about something on here, that’s fine too.
