PROFILE

Mikołaj Świątek

Worked on the grafana/opentelemetry-operator repository, delivering nine features and resolving three bugs over four months. Focused on backend development and Kubernetes operator enhancements, including feature-flagged resource generation, label-based TargetAllocator association, and versioned ConfigMap management for OpenTelemetry Collector CRs. Improved CI/CD automation by integrating Renovate for Go version management and streamlined release processes. Addressed data integrity by fixing negative Unix timestamp handling in the OpAMP bridge. Used Go, YAML, and Makefile to implement robust controller logic, end-to-end testing, and changelog automation, resulting in improved deployment flexibility, operational reliability, and maintainability across multiple OpenTelemetry Operator releases.
