Worked on the mosip/inji-config repository to enhance environment configuration stability and support MDOC integration for testing and deployment. Focused on configuration management by introducing mock-enabled properties and secure issuer key certificate referencing, enabling reliable mock testing and development workflows. Addressed production-like connectivity issues by making the Redis host configurable, replacing a hardcoded value to improve deployment reliability in certify environments. Utilized properties files and configuration management skills to streamline environment provisioning and reduce deployment friction. The work improved testability and reliability for MDOC-related processes, demonstrating a methodical approach to troubleshooting and environment setup using mocking and connectivity best practices.
