PROFILE

Joakim Olsson

Worked on backend reliability and stability, focusing on bug fixes in Go-based systems. In go-gitea/gitea, addressed a release migration issue by implementing robust handling for GitLab releases where asset link and source counts differ, preventing runtime panics and supporting edge cases from GoReleaser-generated releases. In wundergraph/graphql-go-tools, improved GraphQL subscriptions by fixing a WebSocket crash that occurred during authentication failures, ensuring proper connection closure and preventing server panics. Applied Go, GraphQL, and websocket programming skills, expanded test coverage, and adhered to code quality standards, resulting in more reliable automation pipelines and reduced operational risk for real-time backend services.
