About Lucas

I am an entrepreneur as much as a developer. Self-employed since 2021, I build web products end-to-end: database, backend, frontend, deployment, and on-call duty when something breaks at 11 PM.

My current project is called Lucky Nomads. It's a platform that helps people choose where to settle based on their tax situation. I built it alone, and it's live in production: a tax database covering about 200 jurisdictions across 19 domains, around twenty daily tasks that keep it updated automatically, a scoring engine, PDF reports generated and sent automatically, and online payments.

What I do are complete projects, over several weeks or months, from the first screen to going live:

- a complete SaaS platform, with client accounts, subscriptions, and back-office
- a business tool that replaces spreadsheets and hours of manual data entry
- a product with a strong data component: collection, automatic updates, reporting

I primarily work with Next.js and Supabase, deployed on Vercel. It's a stack where I'm fast because I know it in depth, not just on the surface: I know where the pitfalls of caching, costs, and migrations are, and I've already paid to learn them.

What distinguishes me from a pure developer is that I have managed a business from A to Z: acquisition, pricing, margin, customer relations. You don't need to come with a perfect specifications document. I understand your business model, I tell you what will bring you revenue and what will cost a lot for nothing, and I build accordingly. I didn't just code Lucky Nomads: I designed, positioned, priced, and sold it.

No intermediaries, no project managers. You talk directly to the person writing the code.
