Mateusz Poszwa is a pragmatic software engineer with 14 years of experience building low-level, efficiency-minded systems in C and C++, complemented by Python and growing Rust and formal verification skills. He has shipped production features at Arista and Amazon (Ivona/Polly) and previously worked on telecom-grade software at Nokia and kernel-level networking during academic research. Focused on sustainability and open software, he prefers employers that prioritize environmental impact, free software, and energy-efficient toolchains over short-term profit. Comfortable in UNIX-like environments with Emacs and Colemak, he’s intellectually curious about functional languages (Lisps, ML) and has practical experience adapting legacy systems for better diagnostics and resource use. Non-obvious: he rejects roles that force vendor lock-in, excessive travel, or jurisdictions he won’t pay taxes in, reflecting a strong alignment of technical choices with ethical and environmental values.
