During February 2025, contributed to the microsoft/kiota-typescript repository by delivering multipart Content-Disposition filename support, enabling multipart API payloads to include filenames and ensuring accurate header serialization. This feature improved interoperability for file-based integrations, reducing friction for client applications handling multipart requests. The implementation was carried out using TypeScript, with a focus on robust API development and full stack engineering practices. Comprehensive tests were added to verify correct serialization and filename handling within multipart parts, reflecting attention to reliability and maintainability. No major bug fixes were reported during this period, as the workstream centered on focused feature delivery and validation.
