I build data warehouses, AI-powered apps, and polished web experiences. What used to take a team and a quarter, I now ship in days — hand-crafted, not generated from a template.
What I do
Most studios specialize. I cover the full stack from raw data to the interface — and the AI in between. That means no hand-offs, no context loss, and a much shorter path from idea to live product.

LLM-powered apps that ship. Grounded on your data, evaluated, deployed.
Polished web apps and landing pages. Built solo + AI, deployed fast, easy to iterate.
Selected work
Each project is hand-built — no template, no boilerplate site. Browse the case studies for what went into them.
More coming.
Case studies in the pipeline: data-warehouse + AAS work for retail, RAG document chat platforms, internal AI tools.
How I work
01
One developer with the right AI tooling now ships what used to need a small team. You get focus and continuity instead of meetings and hand-offs.
02
Every site is bespoke. No template, no boilerplate landing kit. AI accelerates the build — it doesn't define the design.
03
First demo in days, not weeks. Branches deploy themselves. You see what's coming before it goes live, and we change course while change is cheap.
About
I've been building data warehouses for 15+ years — for retail groups, unions, real-estate operators, and a handful of others who depend on knowing what their numbers really mean.
Lately the work has shifted. The same data foundations now feed AI applications: chatbots that actually know your contracts, agents that compose business plans, semantic layers that keep your AI consistent with your Power BI. The web layer pulls it all together so people can use it.
Stiekema Studio is where I bring those three together. One person, AI as a co-builder, work shipped at a pace that surprises clients.

Let's talk
I'm happy to talk through what you're trying to build — even before you have a brief. The first conversation is free and usually clarifies more than you expected.
