I design and ship production SaaS for real operational problems — queue management, AI receptionists, and C4AI, a secure personal AI workspace that keeps data on our servers. One developer, focused products, built in the Netherlands.
Built, deployed, and maintained end to end — no bloat, just tools that work.
Real-time queue and station management dashboard for APK inspection centers — live customer screen, automated archiving, RDW integration, and customer feedback via QR code.

◐ In development Coming sooncom4all is a one-person software studio based in the Netherlands. I build full-stack, production SaaS — from database schema to deployed UI — for businesses that need software that just works, not another SaaS demo.
Every product starts as a real problem I've encountered myself: an APK station that needed a better way to manage their queue, a business that couldn't answer every phone call, a personal AI assistant to help you without giving out your data. I build the solution, ship it, and support it personally.
