During September 2025, Adazi focused on stabilizing the PostgreSQL adapter within the prisma/prisma repository, addressing a memory leak that affected transactional workflows under high concurrency. By implementing a cleanup function in Node.js and TypeScript, Adazi ensured that error event listeners were properly detached when transactions were either committed or rolled back. This approach prevented MaxListenersExceededWarning and curbed unnecessary memory growth, directly improving resource management and reliability for Prisma users. The work demonstrated a strong grasp of error handling and memory management in JavaScript environments, delivering a targeted fix that enhanced the stability of database interactions without introducing new features.
