Julien Thomas
Work

I am a Barcelona-based full-stack developer building digital products from first decision to production.

I work across architecture, product, and the client conversation. My background in engineering and sales keeps the work technical, useful, and grounded in the people it serves.

Five years in construction sales before moving into product engineering. That commercial background still shapes how I lead client work.

One destination. Every mountain experience.

LAAX brings a complex resort ecosystem into one product: inspiration, live mountain information, accommodation, tickets, ski school, retail, and the operational tools behind them.

I owned the ski school system end to end, from product decisions and booking flows to the admin experience and automated communication. The work grew from a three-person delivery team into a six-person product team.
