Hello Dev 👋

Hey Dev community 👋

I'm Sébastien, based in Geneva 🇨🇭, and I've been shipping web apps for 20 years. Figured it was finally time to stop lurking and start writing here.

What I do

nammu.ch — my web dev agency. Two decades of React, Node, MySQL, and more recently Laravel/Filament. Clients across Switzerland, mostly custom apps and bespoke CMS work.

Kiwi — an AI-powered platform for freelancers. Think CRM + invoicing + AI agents that actually do work for you (not just chat). Currently in closed beta, V1 launching soon.

Aukimi — a browser-based creative suite. 12 professional tools (image editing, 3D, pixel art, vector, and more) running fully in the browser. Inkwell is already open; the rest is rolling out of beta.

What I'll write about

  • Building two SaaS while running an agency (spoiler: it's chaos)
  • WebGPU, Three.js, Babylon.js — the good, the bad, the compiler errors
  • Real talk about React/Node architecture at scale
  • Marketing and distribution as a solo technical founder
  • Occasional rants about DNS, DKIM, and why emails still break in 2026

Excited to meet other builders here. If you're working on SaaS, creative tools, or just love shipping things, say hi 👋

Sébastien
