Full‑stack developer · AI & cloud solutions · Problem solver
I hold a B.Sc. in Business Informatics from Hochschule Osnabrück. Today I work at SIEVERS-GROUP as a Software Consultant & Developer on the SIEVERS AI Hub, an AI platform for mid-sized companies — my job is working out where AI actually pays off, and then building it. By night, I tinker with side projects that remove needless friction from everyday processes. I enjoy pairing rock-solid backends with accessible UIs and a sprinkle of automation.
- Currently building AI-powered call automation for medical practices: local Whisper transcription and an on-premise LLM turn voicemails into cancelled appointments and closed to-dos — without any patient data leaving the building.
- Actively maintaining TheraPlanner, a Laravel-based practice-management SaaS improving patient care in German clinics, and Digitale Vertragsvermittlung, an end-to-end contract brokerage platform built with Laravel 12 & Filament.
- Wrote my bachelor's thesis on an SBOM-based Security Dashboard (Azure Serverless) for compliance under the EU Cyber Resilience Act.
