Summary
I develop software solutions with a strong focus on insurance and broker management systems. I work across frontend and backend, from Angular and TypeScript to Java, Spring Boot and PostgreSQL, and I care about clean, maintainable code, testing and reliable delivery.
I have contributed to broker platforms for around 25,000 brokers, supported the rollout of a broker management program with data migration, and built backend features such as push notification services and Keycloak integration. I am experienced with agile and DevOps-driven work, code reviews, quality assurance, Docker, Jenkins, GitLab, Cypress and SonarQube.
