Summary
🤩
RockstarMichał Nazarewicz is an experienced system-level software engineer and IT advisor with 20 years of hands-on experience in Linux kernel development, low-latency trading systems, blockchain clients, and cross-chain bridges. He specializes in C, C++ and Rust, has authored 180+ accepted Linux kernel patches, and has a track record of reducing node storage costs and improving performance for large distributed systems like NEAR. Comfortable from assembler to TypeScript, he chooses the right tool for the job—whether writing kernel drivers, optimizing SIMD-enabled C++ code, or scripting administrative tooling in Python. Notably, he helped deliver the first Solana–Cosmos IBC bridge and contributes to widely used projects (e.g., rust-rocksdb, pygtrie) improving core APIs and memory behavior. Based in Warsaw, he prefers systems and back-end work over front-end UIs and is selective about crypto roles unless they offer novel technical challenges or exceptional compensation.
