I'm Stijn; a Data & Analytics Consultant. I help energy companies, scale-ups, and mid-size companies make better decisions by connecting their data to something useful. Not another dashboard nobody opens. Not another report that gathers dust. Clarity on what the numbers actually mean for the business.
How I work
I start with the business problem, not the technology. Most of the time, the tools already exist (or can simply be made); someone just needs to connect the dots. I'm pragmatic about what gets built. If a spreadsheet solves the problem, I won't build a pipeline. If a pipeline is needed, I won't automate spaghetti; I'll fix the foundation first.
I'm most useful when the work crosses boundaries; data, commercial systems, marketing, ops. Most data consultants stay in their lane. I don't.
I work best when I'm embedded in the team, not handing off slide decks from the side. Short feedback loops, direct communication, things that ship.
What I do
- Data analytics strategy
- Data modeling & engineering
- AI/LLM integration
- Prompt engineering at scale
- Lead attribution modeling
- Commercial data infrastructure (CRM, marketing platforms)
- Cross-team data quality
Background
I hold an MSc in Data Science & Marketing Analytics from Erasmus University Rotterdam. Since then, I've worked with scale-ups, banks, and healthcare AI startups; but the energy sector is where I've spent the most time. At HalloStroom I built the operational tracking systems for a national solar portfolio: inverter uptime, generation, and Enphase battery systems, later SolarEdge as well. Across HalloStroom and EnergyZero I built a solid track record in energy data analytics and data governance. And I know the hardware side too: I lay solar panels myself. Not professionally, but enough to understand the system end to end.
See recent work for how this plays out in practice.
What I'm not
I'm not a big-corp consultant who shows up with 40 slides and a team of juniors. I'm not building an agency. I'm not chasing the highest day rate. I'm one person who does good work, stays close to the problem, and doesn't overcomplicate things.
