Over a two-month period, contributed backend and API development work to the pantsbuild/pants and semgrep/semgrep-network-broker repositories. Built multi-module support for the golangci-lint plugin in pantsbuild/pants, enabling scalable, per-module linting for large Go projects by partitioning tasks based on go.mod files and maintaining backward compatibility during a major version upgrade. In semgrep/semgrep-network-broker, developed REST API endpoints to validate branch existence across GitHub, GitLab, Bitbucket Datacenter, and Azure DevOps, integrating these checks into the scan scheduling pipeline. Leveraged Go and Python to deliver robust, testable features that improved code quality feedback and operational reliability across diverse environments.
