PROFILE

Jonas Klingstedt

Over a three-month period, this developer enhanced the Sundsvallskommun/api-service-invoice-sender and api-service-messaging repositories by building multi-environment scheduling for invoice processing and improving snail-mail batch delivery reliability. They refactored scheduling logic to support CronTriggers and municipality-based routing, enabling scalable, multi-tenant deployments using Java and Spring Boot. In api-service-messaging, they integrated the Citizen API for address fetching, expanded test coverage, and improved error handling and data validation. Their work included updating OpenAPI specifications, strengthening backend reliability, and replacing Docker Compose with Testcontainers and Samba for more stable integration testing, resulting in improved data accuracy and delivery reliability across services.
