Talk
“Using AI well. Between efficiency, risk and responsibility.”
Technical focus
- Frontend
- Angular for business applications, Astro for websites. Three.js and GSAP for animation, where it suits the brand.
- Backend
- Python with FastAPI as the standard. Node.js for automation, Java with Spring Boot from research.
- Data and infrastructure
- PostgreSQL, Redis or Valkey and MinIO. Docker, Traefik and Terraform, preferably self-hosted at Hetzner.
- Security
- ZITADEL and Keycloak for login, CrowdSec and Coraza WAF against attacks, mTLS between services.
- AI and automation
- Language models from OpenAI, or local via Ollama when data should not leave the building. Playwright and Puppeteer for automation.
Health research
Prevention, longevity and health research are his personal focus. This is where he wants to apply his work as a developer in the long run: with data platforms, analyses and tools for research and clinics.
- Cancer
- Cardiovascular disease
- Alzheimer’s and dementia
- Diabetes and metabolism
- Longevity
- Geriatric medicine
This includes SOMA, the nutrition app.
Away from work
- Outdoors
- Out hiking a lot, plus training at home.
- Music
- Has produced music since 2016 and occasionally DJs. For him it is the same craft as software: many small decisions until something feels right.
- Homelab
- His own servers at home, plus sensors and electronics, down to the soldering iron.
