Worked on improving startup reliability for a containerized Node.js service template in the lokalise/node-service-template repository. Focused on diagnosing and resolving a critical deployment issue by correcting the Dockerfile CMD instruction to accurately reference server.js, ensuring the application starts as intended in production environments. Utilized skills in containerization, DevOps, and Dockerfile syntax to perform root cause analysis and implement the fix, which reduced startup-related incidents and contributed to smoother release cycles. The work demonstrated a methodical approach to debugging Docker-based deployments and enhanced the overall production readiness of the service without introducing new features during the development period.
