Summary
👤
Senior🎓
Top SchoolMaciej Małkowski is an engineering manager based in Berlin with over a decade of hands-on software development and leadership experience across full-stack JavaScript, .NET, and large-scale frontend migrations. He has a track record of building and growing teams, driving architecture unification that cut operational costs and boosted group velocity, and delivering product rewrites that reduced tech debt while improving conversion. At Klarna and Agoda he led cross-organisational initiatives—component libraries, eslint rules, and migration efforts—that measurably increased engineering velocity and reduced maintenance overhead. Pragmatic and metrics-minded, he combines low-level systems experience from Intel with consumer-facing product work, and is motivated by exploring new technologies and solving unique challenges. An engineer at heart who “likes building things,” he balances technical delivery with mentorship and hiring to scale high-performing teams.
