I build practical automation systems and backend tools — often where software meets real-world operations.
Based in Switzerland 🇨🇭
- Backend development (Python)
- Data & persistence (SQL / SQLite, structured data modeling)
- Automation & reliability (schedulers, state, fault tolerance)
- Applied IoT systems (sensor ingestion, control logic, dashboards)
A real-world irrigation controller for a ~70 m² garden.
Raspberry Pi backend + sensor nodes + weather-aware decision logic + historical logging.
Highlights
- Flask backend + SQLite logging
- Sensor ingestion from ESP32 nodes (HTTP POST; MQTT planned)
- Automation logic for multi-zone watering
- Weather integration (Open-Meteo)
- Built to evolve into predictive optimization (ML-assisted irrigation)
A small front-end web app for calculating recipe cost, portion cost, and selling price using food cost % and factor-based pricing.
Highlights
- Real-world gastro use case
- Unit conversion (g/kg, ml/dl/L)
- Responsive design
- Clean modular JavaScript structure
- API design patterns & testing
- Data workflows (pandas, reporting, quality checks)
- Architecture: modular services, messaging, and resilience
- Swiss-market practical tooling (documentation, maintainability, real constraints)
Experience across operations-heavy environments (hospitality, maritime, technical support) with a strong focus on systems, process reliability, and execution.
