Over a two-month period, contributed to backend and DevOps improvements across schubergphilis/mcvs-golang-action and grafana/mcp-go. Enhanced code quality and workflow by upgrading golangci-lint to v2.0.1 and consolidating formatting tools, establishing a unified linting process in Go and YAML that reduced duplication and streamlined CI/CD. In grafana/mcp-go, developed a middleware framework for MCP Server Tool Execution, introducing customizable middleware layers with robust error handling and panic recovery. This foundation supports future extensibility and observability for tool integrations. The work focused on maintainability and reliability, leveraging skills in Go, middleware design, and automated code quality enforcement without direct bug fixes.
