Top SchoolBoris Mattijssen is a versatile software engineer with over a decade of experience blending backend architecture, data science, and DevOps, currently shaping systems at Picnic Technologies. He pairs a Master’s in Computer Science from TU Delft with hands-on leadership as a lead developer, owning API and microservice design, authentication, CI/CD, and mentorship across startups and scale-ups. His background spans building Kubernetes extensions and presenting at KubeCon to designing experimentation tooling and sequential testing methods at Booking.com, reflecting depth in distributed systems and statistics. Boris has repeatedly moved between engineering and ML roles—shipping forecasting and bandit-based solutions at Adyen, Vandebron, and Booking—so he comfortably bridges research-grade methods and production constraints. Notably, he launched his first software business at 16 and has a track record of turning complex integration challenges (on-prem + cloud) into pragmatic, maintainable platforms.
