Enkodo, Groningen
Enkodo builds software, from the interface to the server underneath.
I'm Sebastiaan. I always want to know how things work. For the bigger jobs I bring in people I've known for years.
What Enkodo builds
Four kinds of work that overlap more than this list suggests.
Apps
Apps for iOS and Android with React Native, from a single codebase.
Web platforms
Full-stack web applications with Next.js, from company platforms to products of my own.
Backends & infra
Node.js services, databases and realtime systems, on infrastructure I manage myself.
Automation & own products
Integrations between systems, Home Assistant automation and my own tooling for backups and server management.

GitHubEnkodo builds software for companies across the Netherlands, plus the systems around it: servers, deployments, monitoring, automation.
A lot of that work is long-term maintenance. I've kept some apps running for seven years, through every OS update and redesign. I genuinely enjoy that work, boring as it sounds.
Everything runs on my own servers.
About SebastiaanI'm curious what you're building.
Even if it's still half an idea. I usually reply within a working day.
