Senior Computer Specialist
CurrentAs the Sr. Computer Specialist, I spearheaded a major upgrade to our Java-based systems, transitioning from Java 8 to Java 11 while integrating robust X.509 certificate authentication. This ensured secure communication between Jira, Confluence, and our custom LDAP service. I didn’t just update libraries—I re-envisioned the entire server architecture, reducing the server footprint from 7 to 5 by migrating from CentOS 7/Postgres 13 to Ubuntu 22.04/Postgres 16, which significantly reduced technical debt and streamlined system performance. Alongside these technical improvements, I created a comprehensive Atlassian guidebook, simplifying complex system administration tasks and user workflows. My cleanup of unused assets led to over a 200% improvement in system indexing speeds. I also introduced change management protocols that reduced untested code deployment in production, greatly minimizing errors.
