July 2025 monthly summary for JobService/job-service. Delivered a configuration management overhaul that decouples config from Spring by introducing a dedicated Environment class to read properties from system environment variables, replacing Spring's Environment and @PropertySource. This directly reduces Spring AppContext memory leak risks, simplifies deployment, and improves environment-based configuration clarity. The change aligns with 12-factor app practices and enhances testability and startup reliability.
