Worked on stability and integration improvements across pixijs/pixi-react and sanity-io/sanity repositories, focusing on bug fixes and dependency management. In pixijs/pixi-react, addressed a type-safety issue by updating TypeScript definitions to support nullable refs in ApplicationProps.resizeTo, reducing runtime errors when refs are temporarily unavailable and improving the resilience of the resize workflow. For sanity-io/sanity, enhanced package configuration by adding sanity to the peerDependencies of @sanity/vision, aligning dependency declarations to prevent integration issues and improve downstream reliability. Utilized TypeScript, JSON, and frontend development skills to ensure safer, more maintainable codebases and smoother developer experiences for consumers.
