A small map of me.

I'm Keshav, in Mathematics and Computing at NIT Kurukshetra. Most of my work lives in open source: tools I build myself, and careful fixes to projects I use and admire.

I started contributing about a year ago. RoboSats was where I learned. It's a peer-to-peer Bitcoin exchange that runs over Tor, and the code there is unforgiving in a useful way: real users, real money, real bugs that hurt when you ship them. The piece I'm proudest of is an end-to-end encrypted image flow for the trade chat. People send screenshots of bank transfers and gift cards through there now, and the server never sees a thing.

I also build my own things. Stashu is the main one: a small marketplace where anyone can sell a digital file for a tiny payment, with no account and no middleman touching the file. It uses browser-side encryption, Blossom for storage, and Cashu ecash for payments, with Verified Peek so buyers can check a preview before unlock. The first time someone I'd never met paid for a stash was a strange and lovely afternoon.

This summer I'm on Joplin's Google Summer of Code, working on local-first note encryption. On the side I'm folding three smaller Bitcoin transaction tools into txray.dev. I'm currently Executive Head of Tech at Anant, the math society at college, where I designed the visual identity and built the site.

Outside the terminal: a lot of football (Barça, all my life, with respect for both Messi and Cristiano), Elden Ring and whatever it leads me to next, and a quiet stack of books I'm always halfway through. I don't write essays yet. I'm working on that.

A short timeline

• 2026 / now GSoC with Joplin. Stashu v0.2 live. TXRay live and growing.
• 2025 / 2026 Found my way into open source. Most of my work landed in RoboSats, with smaller PRs to Alby, Minibits, BTC Map, and Joplin along the way.
• 2024 Joined Anant, the math society. Designed the visual identity, built the site, and now help lead the tech team.
• 2023 / 2027 B.Tech in Mathematics and Computing, NIT Kurukshetra.
