Kacper contributed to backend and infrastructure projects, focusing on API evolution, observability, and automation. In spacemeshos/go-spacemesh, he developed new API versions and standardized access patterns using Go and gRPC, improving client compatibility and long-term maintainability. He enhanced transaction and activation data visibility through logging and new RPC endpoints, supporting traceability and reliability. For coder/terraform-provider-coder, Kacper implemented the coder_external_agent resource in Go, enabling reproducible infrastructure automation via Terraform. He also improved cross-IDE integration in coder/coder-jetbrains-toolbox and vscode-coder, adding explicit build reason support and CLI compatibility. His work demonstrated depth in API development, infrastructure as code, and CI/CD.

August 2025: Delivered the new coder_external_agent resource in the Terraform provider coder/terraform-provider-coder, enabling customers to define and manage external agents within a workspace by referencing the coder_agent ID. The feature includes a complete resource schema, creation logic, and user-facing documentation. This work enhances automation, standardizes external agent provisioning, and reduces manual configuration across environments. Commit reference: e04ea9c09cae938ca568a14aadc5e65e1ac97026 with message feat(coder-attach): add coder_external_agent resource (#424).

July 2025 performance review: Focused on delivering cross-IDE workspace start build reason support to improve observability and troubleshooting. Implemented explicit build reason signals for JetBrains and VS Code integrations and ensured compatibility with newer Coder CLI versions. No major bugs documented; efforts centered on feature delivery, code-model updates, and telemetry enrichment across two repos.
