Worked on enhancing developer experience and schema consistency in the getoutreach/stencil-golang repository by implementing two core features focused on configuration management and DevOps practices. Developed an End-to-End Test Aware Watch Rebuild, updating AIR configuration to monitor E2E test changes and trigger rebuilds, which streamlined the feedback loop and accelerated development cycles. Introduced GraphQL Schema Local Synchronization using Go and YAML, enabling binary synchronization of the schema within the development container through a new devspace.yaml configuration and local snapshot. These improvements ensured local environments accurately reflected server state, supporting faster iteration and safer deployments without introducing new bugs during the period.
