The main entry point for every incoming insurance application at one of the largest insurers in the Netherlands. I extended it to dozens more employers, cut the internal errors that were stranding applications, and designed and ran the release process around it.
The application flow and the calculation tool beside it are how a.s.r. takes in new business. Together they are used by hundreds of thousands of people, and the person on the other end of the screen is arranging cover for something that matters to them. Sensitive personal data goes through it at every step. I worked on it in a scrum team of 7 developers, 9 people in total.
A multi step application has no forgiving kind of failure. An internal error part way through does not show up as a bug report, it shows up as a person who gave up and did not come back, and neither they nor a.s.r. get anything out of that. Every step also handles sensitive personal information, so security and data correctness are not qualities you balance against delivery speed. They are the floor.
This is the work I am doing now, and I am available for a new engagement from 1 January 2027.
