Summary
👤
Senior🎓
Top SchoolTim Van Steenis is a pragmatic technology leader with 11 years of experience who currently serves as Head of Technology at LessonUp, scaling the engineering organisation from 6 to 18 while modernising the platform and preparing it for high scale. He is primarily an iOS developer (Swift/Objective-C) with solid backend chops in C# and Java, and has led migrations from legacy stacks to modern architectures (React, NodeJS, MongoDB, Kubernetes, GCP) without sacrificing feature delivery. Tim blends hands-on coding and architecture direction—introducing GitOps, CI/CD, QA processes and Kubernetes—then shifts responsibilities as teams mature. His background at Q42 spans technical leadership on consumer and IoT products (HEMA, Philips Hue) and large public-facing projects for museums, showing a knack for building scalable, user-focused systems. Based in Zoetermeer, he pairs product-minded engineering with organizational growth experience, often stepping into client roles that later turn into longer-term leadership engagements.
