01 / The problem
Clinical software has to translate dense domain rules and connected care workflows into an interface that remains clear during real consultations.
Who it was for
Healthcare professionals working in Belgium.
Why it was difficult
Balancing product change with the safety, continuity and domain precision expected from clinical software.
02 / My exact role
Full-stack development, functional and technical design, production problem-solving and progressive modernisation.
03 / Constraints
- Sensitive medical data and regulated workflows
- End-to-end encryption and per-user private keys

- Belgian eHealth interoperability requirements
- Many interconnected business rules
04 / Technical & product decisions
- 01
Model workflows across frontend and backend instead of treating the interface in isolation.
- 02
Improve the existing system incrementally to protect production continuity.
- 03
Prioritise maintainability, interoperability and observable production behaviour.
