Building hospital interoperability, AI agents and on-device ML. I pair two decades of business leadership with modern software management — turning research into systems that hold up in the real world, with sustainability and innovation at the core.
A digital care platform for people with fibromyalgia, CFS and FNS at PXL Smart ICT. As Scrum Master I designed a reusable, AI-assisted project blueprint — GitHub Actions CI/CD and open-source governance — so civic-tech initiatives become sustainable and repeatable instead of restarting from zero.
Leading the Octogrid ESB at Jessa Hospital — agent/orchestrator development carrying HL7/FHIR messages so clinical systems exchange medical data safely and seamlessly. Full-stack in Kotlin and Vue.js.
A startup concept and desktop build for real-time sign-language translation. Computer vision and on-device ML inference recognise signs and translate them to text — bidirectional accessibility for the deaf and hard-of-hearing community.
A complete full-stack application — backend and frontend built with modern .NET technologies and clean architecture principles.
- Blueprint and operational manager for Civic Tech pilot cases using Agile/Scrum.
- Designed an architectural blueprint for research-project scalability and repeatability.
- Built a CMS dashboard for knowledge management and project tracking.
- Coordinated cross-functional teams and kept stakeholders aligned on outcomes.
- Leading the Octogrid ESB — agent/orchestrator development.
- Implementing HL7/FHIR healthcare-interoperability solutions.
- Full-stack development with Kotlin and Vue.js.
- Managing stakeholder requirements and delivery.
- Founded the Visear concept — real-time sign-language translation using AI/ML.
- Designed cross-platform, AI-powered bidirectional translation (speech-to-sign & sign-to-speech).

Reliability is the feature.
In healthcare, software failure has a cost measured in care, not clicks. I design for correctness, observability and graceful failure before anything else.
Lead by clearing the path.
Seventeen years of leadership taught me the job is to give people a clear problem, the context to solve it, and the cover to do it well — then get out of the way.
Standards & sustainability over heroics.
HL7, FHIR, reusable blueprints, open-source governance. Systems built on shared standards outlive any single clever solution — and keep working after the team changes.
Contributing to civic-technology projects that improve government services and citizen engagement — building open-source solutions for public-sector challenges alongside government agencies and civic organisations.
Hogeschool PXL — Applied Informatics. Represented student interests in program-level decisions, gave feedback on curriculum and exam schedules, and helped improve student-support services.
