Summary
🤩
Rockstar🎓
Top SchoolMartin Milata is a firmware engineer with 14 years of hands-on experience building secure, low-level software and infrastructure tooling, currently focused on Trezor's firmware. He specializes in Python, Rust and C on Linux (notably NixOS), and brings deep debugging, performance tuning and TCP/IP networking skills from roles at Red Hat, Ubiquiti and open-source projects. Martin is an active open-source contributor — his work spans Bitcoin-related Nix modules (nix-bitcoin), improvements to Trezor firmware UX and auto-lock behavior, and robustness fixes in networking libraries like libwebsockets and Twisted. He combines systems-level rigor with practical DevOps sensibilities, having added LND/bitcoind integrations and policy-based fee tooling to production-grade stacks. Based in Brno, he pairs academic depth from Masaryk University and a semester at Aalborg with pragmatic, security-minded engineering across embedded and distributed systems.

Their commits involved modifying existing C code and Python scripts to handle edge cases, such as out-of-range values for the auto-lock delay. They also worked on enhancements to the wallet's error handling during settings changes and integrated code to confirm these changes via the device interface, also improving the string representation of the auto-lock settings in the UI.
