Summary
👤
Senior🎓
Top SchoolOndrej Valenta is a pragmatic entrepreneur and senior software engineer based in Prague, leading KEEN|MATE as owner, mentor and principal developer with over 15 years of C# and ASP.NET experience and a deep history in SharePoint and SQL Server. He builds full-stack solutions—from Vue/Svelte frontends and ASP.NET Core backends to Elixir/Phoenix real-time systems—while also developing internal tools like an Ecto generator and performance-focused AdminLTE variants. Ondrej combines hands-on architecture, database design and performance tuning with CI/CD and observability practices (Docker, Drone, Graylog, Prometheus) to deliver applications used daily by thousands. He’s equally invested in teaching: he founded an apprenticeship program and has mentored high-school students into professional developers. Comfortable across Windows and CentOS environments, he prefers pragmatic, high-performance stacks and often chooses less common technologies (Elm, Elixir) when reliability and speed matter. Colleagues describe him with playful confidence; beyond coding he’s built a small, tightly knit team that mirrors his teaching-first approach.
