What people often ask me.
A few clear answers about what I do, how I work, and how to reach me.
- What does Thomas Wirtz do?
- I am an independent full-stack & AI developer based in Strasbourg, France. I design web applications, business tools and SaaS products, from clarifying the need to shipping to production.

- Business apps and SaaS, APIs / data / integrations, automation and AI (including agentic workflows), and taking over existing projects: audit, maintenance and migration.
- Are you available for new work?
- I already have a main client, but I keep time for short missions: fixes, evolution, or a small product delivered end to end. I usually reply within 24 hours.
- How and where do you work?
- From Strasbourg, remote or on-site, at a fixed price and outside my client hours. I share a budget range at the first exchange, after a quick scoping.
