PROFILE

David Pacheco

During four months on the oxidecomputer/dropshot and oxidecomputer/propolis repositories, Dap developed and enhanced multi-version API capabilities, implemented granular version targeting, and improved release workflows. They introduced an experimental API versioning framework in Rust, leveraging Semver and OpenAPI Specification to enable flexible endpoint registration and safer API evolution. Dap also delivered a security-focused bug fix to prevent internal error exposure, updated error handling, and maintained changelogs and release documentation. Their work included expanding mock server tooling in Propolis, refining build and release management, and ensuring repository hygiene. The engineering demonstrated depth in backend development, version control, and documentation practices.
