Senior🎓
Top SchoolPeter Van T Zand is an experienced IT consultant and engineer with 11 years building scalable web platforms, transitioning from a backend Python/Flask specialist into a full-stack leader working with Ember/JS and React. After earning a BSc in Artificial Intelligence from the Universiteit van Amsterdam, he chose web development over pure AI and organically grew into the CTO role at CloseAlert, owning AWS operations, CI, backend and database performance. He architected The Markers from scratch—implementing its backend, frontend and CI/AWS operations—and split his time between product work and infrastructure since 2019. Peter is also an active open-source contributor, improving cron scheduling in the widely used rq-scheduler Redis job library and fixing compatibility edge cases. He prefers roles in larger engineering teams where he can apply both hands-on coding and operational leadership to scale reliable systems. Based in North Holland, he brings a pragmatic mix of product-focused development and deep operational responsibility.
