Worked on architecture and reliability improvements across two repositories, focusing on maintainability and robust API interactions. In TypeCellOS/BlockNote, delivered centralized style exports by restructuring CSS and SCSS files, enabling modular imports and standardizing stylesheet usage throughout the application. This change improved maintainability and streamlined frontend development workflows. In google/adk-js, addressed a concurrency edge case in Gemini’s streaming API by ensuring consistent propagation of the thoughtSignature parameter, which prevented 400 errors and improved contract compliance. Leveraged TypeScript, CSS, and API integration skills to deliver targeted solutions that enhanced code quality, reduced error rates, and supported more reliable downstream integrations.
