Worked on the is-a-dev/register repository to deliver configuration-driven enhancements supporting the rollout of the A-LEMS project. Focused on improving deployment reliability and site availability by introducing a new JSON configuration file and extending existing configurations with multiple records and external resource links. Updated DNS and domain settings, including CNAME adjustments and cleanup of DNS entries, to ensure accurate resolution for the new portfolio site. Emphasized configuration management and DNS management skills, with all changes tracked through explicit commit history for traceability and auditing. The work addressed deployment challenges and reduced DNS issues across different environments, leveraging JSON for configuration updates.
