SStiekema Studio

Data · AI · Web

One developer.
A studio of one, augmented by AI.

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

Three disciplines, one practitioner.

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.

Data Engineering

Data warehouses, pipelines, models. The foundation reporting and AI need to be trustworthy.

  • SQL Server · Azure · Snowflake
  • Dimensional modeling · ETL · lineage
  • Production-grade data quality

AI Products

LLM-powered apps that ship. Grounded on your data, evaluated, deployed.

  • Claude · Gemini · OpenAI
  • RAG · tool use · agents
  • Prompt engineering + evals

Web Development

Polished web apps and landing pages. Built solo + AI, deployed fast, easy to iterate.

  • Next.js · React · TypeScript
  • Tailwind · design systems
  • Vercel · Azure · Cloudflare

Selected work

Recent things I've built.

Each project is hand-built — no template, no boilerplate site. Browse the case studies for what went into them.

How I work

Small team economics, studio-grade craft.

01

Solo, augmented by AI

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

Hand-built, not generated

Every site is bespoke. No template, no boilerplate landing kit. AI accelerates the build — it doesn't define the design.

03

Ship fast, iterate live

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

Bas Stiekema.

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

Got data that
should become a product?

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.
