As part of the Entrepreneur of General Interest program started by Etalab (French task force for Open Data), I worked on simplifying administrative formalities for professional sailors by making user-friendly apps and human-friendly code 🌊 More precisely, I developed a service allowing professional sailors to request their training titles. On the backend, I : - implemented a hexagonal architecture ; - worked in TDD (JUnit) ; - implemented from scratch a rule engine that analyses legal requirements formalised in JSON ; - used Java, Spring Boot & Data, PostgreSQL. And on the frontend : - created an interface allowing a sailor to request a training title ; - worked with the State Design System (Système de Design de l'État) ; - used React & Redux.
