I'm an engineer who builds products. I'm a founding engineer at [Youe.co](https://youe.co), where I own the backend and infrastructure, and I ship my own products under [Vantible](https://vantible.com): [axonpush](https://sayanbiswas.in/p/axonpush) and [Kaiwa](https://sayanbiswas.in/p/kaiwa).

I've been writing open source since I was a teenager, and I still maintain [Kigyo](https://sayanbiswas.in/p/kigyo), a Telegram bot 5M+ people rely on. I like owning the whole thing: the schema, the infra, the interface, and keeping it up long after launch.
