Figured it was finally time to stop lurking and start writing here.</p> <h2> What I do </h2> <p><strong><a href="https://nammu.ch" rel="noopener noreferrer">nammu.ch</a></strong> — 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.</p> <p><strong><a href="https://app.kiwi" rel="noopener noreferrer">Kiwi</a></strong> — 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.</p> <p><strong><a href="https://aukimi.com" rel="noopener noreferrer">Aukimi</a></strong> — 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.</p> <h2> What I'll write about </h2> <ul> <li>Building two SaaS while running an agency (spoiler: it's chaos)</li> <li>WebGPU, Three.js, Babylon.js — the good, the bad, the compiler errors</li> <li>Real talk about React/Node architecture at scale</li> <li>Marketing and distribution as a solo technical founder</li> <li>Occasional rants about DNS, DKIM, and why emails still break in 2026</li> </ul> <p>Excited to meet other builders here. If you're working on SaaS, creative tools, or just love shipping things, say hi 👋</p> <p>Sébastien</p> ai javascript showdev webdev
