Summary
👤
Senior🎓
Top SchoolMaarten Ackermans is a founding engineer and full-stack developer with a decade of experience building web products from infrastructure to UX, currently based in Barcelona and co-founding early-stage teams including Float and Supercut. He shipped high-impact features at Typeform—accelerating signups and subscriptions, building an integrations framework, and driving GDPR-safe data flows—and later scaled product and delivery as a staff engineer at Maze. Comfortable across backend, frontend and QA, he contributes to open-source testing tooling such as enhancements to the Puffing Billy proxy, improving request-stubbing and cross-origin testing with Watir support. Maarten blends startup grit with systematic engineering: he moves quickly to prototype and also builds the test and events infrastructure that keeps products reliable and compliant. His career began in hands-on roles from embedded and operations tooling to dev tooling and consulting, giving him a broad systems perspective that surfaces non-obvious risks early. He pairs entrepreneurial instincts with a pragmatic focus on measurable product outcomes.
