Worked on stabilizing the vechain/vechain-kit repository by addressing an API integration issue related to IPFS uploads. Focused on restoring previous API behavior for image, metadata, and blob uploads by reverting an unintended change to the X-Project-Id header. This targeted rollback, implemented using TypeScript and JavaScript, maintained backward compatibility and minimized the risk of client-facing regressions. The approach reduced potential customer support overhead by ensuring that existing integrations continued to function as expected. Demonstrated attention to detail in frontend development and API integration, prioritizing stability and reliability in production environments while minimizing disruption for downstream users and clients.
