Kalle Jokinen enhanced observability for the City-of-Helsinki/kukkuu repository by implementing structured JSON logging for the uWSGI server. He updated the Dockerfile to include the necessary configurations and dependencies, leveraging his skills in containerization, DevOps, and Docker. This work enabled the application to produce logs in a consistent, machine-readable format, making them easily parsable by common logging backends such as ELK and Splunk. The changes improved both deployment and developer experience by standardizing log output across environments, laying a foundation for more effective monitoring, alerting, and root-cause analysis. The work demonstrated focused depth within a targeted feature.
