Selected work.Teams that shipped faster.
AI tooling that helps developers ship with less friction.
Built GraphQL guardrails that catch dangerous schema changes at every stage of development, from local work and AI-steered changes to commits and pull requests, so what gets built is correct. Improved the application deployment pipeline and made package installs more reliable. Created reusable agent tooling for custom development workflows across desktop, terminal, and web.
