À propos de Sébastien

I’m a founder who codes.

I co-founded Coddy — urban escape games running in 10+ countries. I’ve also shipped Harmonia, Crewsade, and Attic Gaming. Real products, real users, real constraints.

When I take freelance missions, I bring that same mindset: I think about your product, challenge the weak spots, and build things that work at scale — not just things that demo well.

What I build:
∙Custom web apps and SaaS platforms — no CMS, no templates, no shortcuts
∙AI automations that eliminate repetitive tasks (up to 80%)
∙Internal tools, dashboards, and admin panels your team will actually use

Stack:
Laravel · Vue.js · Astro · n8n · AI integrations · Clean APIs

Who I work with:
∙Founders who need a senior dev without hiring one
∙Agencies who need an extra brain, not just extra hands
∙B2B companies replacing spreadsheets and manual processes with real tools
What’s different:

I’ve been on the product side. I know what breaks at scale, what users actually need, and what features are a waste of everyone’s time. I’ll tell you — even if you didn’t ask.
