Rockstar🎓
Top SchoolAndrew Milich is a software leader and founder with 11 years of experience building secure, product-focused systems from embedded firmware to consumer SaaS. He co-founded and led Skiff to 2.5M users and end-to-end encrypted email, calendar, and docs before the Notion acquisition, then led Notion Mail and later served as Head of Engineering for product at Cursor. Now at xAI as a Member of Technical Staff, he blends product leadership with hands-on engineering—his open-source work includes low-level embedded contributions to the widely used Tock OS (Nordic nRF51 UART drivers, RF233 radio userland, and sensor drivers). Comfortable across cryptography, UI, and systems stacks, he pairs Stanford CS training (AI focus) with a track record of shipping privacy-first, scalable products. Notably, he has shifted repeatedly between building and integrating startups into larger platforms, bringing both founder grit and execution at scale.

Contributions summary:Andrew primarily contributes to the `tock/tock` repository, a secure embedded operating system, by making changes related to the Nordic nRF51 microcontroller. Their work includes modifying UART (Universal Asynchronous Receiver/Transmitter) drivers, including enabling interrupts, sending and receiving bytes, and configuring baud rates. They also introduced a userland application for an RF233 radio module, including send/receive API, and added a driver for the FXOS8700CQ accelerometer with a userland application.
