Contributed to the TechStartupClub/UMarket repository by building a containerized backend infrastructure supporting microservices for authentication, market, and social features. Established centralized PostgreSQL database connectivity with standardized configuration, connection pooling, and secure environment variable management using Node.js and Docker Compose. Developed per-service Dockerfiles and orchestrated deployments to streamline local development and ensure reproducibility across environments. Addressed a critical authentication service bug by correcting database pool imports and sanitizing environment variables, which improved deployment reliability and security. The work emphasized maintainability, onboarding efficiency, and infrastructure-as-code practices, resulting in a scalable, stable foundation for both development and production workflows.

Feb 1, 2025February 2025: Delivered containerized deployment and environment standardization for the UMarket app, establishing Docker Compose orchestration, aligning Node.js versions across services, and standardizing environment variable handling to support local development and seamless deployment. Fixed a critical DB connectivity issue in the Authentication Service by correcting authPool import and cleaning docker-compose environment variables to prevent leakage. These efforts increased deployment reliability, reduced environment drift, and accelerated developer onboarding while strengthening security and maintainability of infra.
