Worked on the opentiny/tiny-engine repository with a focus on backend stability and data integrity, addressing two critical bugs over the course of a month. Improved API reliability by correcting endpoint URL formatting, which reduced 404 errors and ensured that deploy and create requests reached the intended endpoints. Enhanced database management by updating a MySQL query to use the correct field for identifying build materials, preventing data mismatches during updates. Utilized JavaScript and TypeScript for API integration and backend development, demonstrating attention to detail in maintaining robust data flows and ensuring consistent application behavior without introducing new user-facing features during this period.
