Summary
🤩
RockstarJan Pochyla is a Senior Rust Engineer based in Prague with 14 years of experience building robust, performance-sensitive systems across embedded firmware, back-end services, and native UIs. He spent nearly a decade at SatoshiLabs working on Trezor firmware, tooling and back-end infrastructure—contributions that span low-level Rust/C integration, transport protocol hardening, and blockchain index optimizations. At Rayon and in open-source projects he focuses on front-end work for Rust-native toolkits and cross-platform native clients, improving UI performance and ergonomics (notably in druid and a native Spotify client). Jan combines embedded systems insight (MicroPython/Rust bindings, USB and memory debugging) with server-side and database expertise (RocksDB repairs, block parsing), making him comfortable across the full stack of constrained and large-scale environments. He’s pragmatic about cross-platform compatibility—evidenced by MSVC fixes and browserify tests—and favors shipping thoughtful, maintainable changes that improve both developer and user experience.
