The Author

Currently fullstack at Xinchuan, building a SIM card management platform with Go on the back end and Next.js on the front. Before that: AI tooling at Tempo Labs, and three years of open-source blockchain work at Berlin-based Rotki, from wallet integrations with WalletConnect to real-time data visualisation and the patient tuning of performance for more than ten thousand users.

Evenings belong to Swift: three iOS apps of my own on the App Store, from a chat trivia game to a prayer-powered screen time blocker.

Outside of work, you will find me on the padel court.
