Anton Timmermans is a pragmatic founder and seasoned software engineer with 11 years of experience building pragmatic web solutions and leading teams from prototype to production.

As a serial founder and freelance tech lead, he focuses on solving the actual problem rather than shipping the shiniest architecture, guiding teams through pragmatic trade-offs and scalable implementations. His background in both UI improvements and backend database optimizations shows a rare comfort across the stack, and his work on Gutenberg's editor and Yoast's Indexable_Repository highlights impact on widely used content platforms. Based in the Arnhem‑Nijmegen region, he pairs entrepreneurial drive with a steady engineering hand to turn real user needs into lasting software.
