I build the software behind your products.
Backends, APIs and serverless infrastructure on AWS, plus apps for iOS, Android and the web. From concept to production.
Software
What I build for companies
AWS & Serverless
Infrastructure that scales with demand and needs little upkeep. Defined as code, so every change is traceable.
Lambda · Serverless Framework · Amplify
Apps & Web
Mobile apps and web interfaces that work cleanly with your backend.
Swift · SwiftUI · Vue.js
Network & Security
Company networks with clearly separated zones and secure remote access. Applications that are built to be secure from the start.
UniFi · VLAN · VPN · Firewall
Featured project
nomos: smart home control in one app
nomos brings home automation and smart home devices together in a single app. At nomos system AG I work in development: on the app, on the controller in the house and on the cloud services that connect the two.
As an integrator I also install nomos myself. So I know the system from both sides.
Platforms iPhone, iPad, Android, Apple Watch
Integrations KNX, Feller, Eltako, Busch-Jaeger, Sonos, Miele, Shelly, Philips Hue, Home Connect, Somfy and many more
Operation Encrypted, optionally fully offline
My role Development and integration
Smart home
When the building is done, I make it smart
Once the electrical work and building services are in place, I take over. I connect the layers that would otherwise run side by side: KNX installation, lighting and shading, heating and ventilation, appliances, audio, cameras and network. If a device has no ready-made integration, I build one, down to writing my own drivers.
A smart home is only as secure as its network. That is why smart home devices, cameras and guest Wi-Fi each get their own network (VLAN). Your computers and personal data stay separate.
You see your cameras live in the app and on the wall panel. Recordings are stored in your house, not in someone else’s cloud.
In the end you control everything with one app, at home and on the go. For new builds and retrofits.
