René Bulsing
René brings clarity to complexity. Whether that complexity sits in a tangled domain model, a system nobody dares to change, or an AI tool that produces confident nonsense at speed, his approach is the same: see the bigger picture, make it click, and translate it into something that holds up. With a Master’s in Software Engineering, over ten years of Java backend experience, and a background as Tech Lead and Team Lead at Xebia, he teaches the way he works — hands-on, on real problems.
Technology keeps accelerating, and with speed comes complexity. What drives René is bringing clarity to that complexity: seeing the bigger picture, making everything click, and translating it into solutions that hold up over time.
He holds a Master’s in Software Engineering and has over ten years of Java backend experience across finance and e-commerce, plus a background as Tech Lead and Team Lead at Xebia. He adapts quickly to new domains, sets clear technical direction, and bridges business goals with execution. For René technology is an enabler, never a goal in itself — which is why he builds robust, simple systems rather than clever ones.
Today he applies AI to amplify his own effectiveness and that of the teams around him, and helps organisations move from experimentation into practical adoption. In training he works as
he does on engagements: real problems, honest trade-offs, and techniques that survive daily practice.
