Amsterdam, North Holland, Netherlands
Summary
👤
Senior🎓
Top SchoolMaciej Kopias-czekay is a seasoned technology leader based in Amsterdam with over 10 years of experience building and running backend systems, primarily in Perl and MySQL. As Team Leader of Booking.com’s Perl Infra team he balances hands-on problem-solving with people leadership, preferring to mentor and grow engineers rather than focus solely on code. His career spans deep systems work—from realtime billing and SIP/RTP extensions to scalable CMS and PDF generation pipelines—showing a knack for tackling the “scary” technical problems others avoid. He blends technical craft with creative interests (LaTeX, LilyPond, MIDI and improvised electronic/jazz music), which surfaces in unconventional problem-solving and a pragmatic engineering aesthetic. Preferring Amsterdam-based or predominantly-remote roles, he values work that’s useful, enjoyable, and visible to the business. Colleagues describe him as someone who elevates teams by treating people as the hardest and most important part of software delivery.
