Rockstar🎓
Top SchoolMykola Orliuk is a seasoned software developer with 14 years specializing in Unix and network-oriented systems, currently building backend solutions at Amazon from Luxembourg. He has a strong track record as a senior Unix developer and technical lead across telecom, finance, and embedded platforms, including roles at Luxoft, UBS and webOS where he shaped local architecture and Linux integration. Mykola contributes to notable open-source projects such as wlroots (Wayland compositor library) and hledger, improving low-level input handling, memory safety, and Haskell-based accounting logic—work that underscores his comfort across C/low-level systems and functional languages. He combines pragmatic system design with careful attention to stability and correctness, frequently addressing memory leaks, device initialization, and multi-commodity transaction accuracy. Always curious about new technologies, he pairs deep Unix expertise with a history of cross-domain problem solving, from telecom middleware to UI compositor backends.
