My work experiences across different companies and roles.
September 2025 - Present
Ottawa, Ontario
• Architected a centralized CI/CD observability platform on Grafana and Loki, aggregating pipeline telemetry from 100+ GitLab repositories to cut failure-investigation time across teams.
• Built real-time CI telemetry pipelines in Python against the GitLab API, running ~96 scheduled executions per day and streaming structured logs into centralized logging infrastructure.
• Engineered pipeline flakiness detection by correlating repeated runs per commit SHA, and layered AI-driven diagnostics on top for log summarization, failure classification, and root-cause analysis.
• Drove adoption of GitLab merge queues and CI gating policies across 50+ repositories, keeping shared branches stable under concurrent development.
• Automate platform infrastructure with Go, Terraform, Ansible, and VMware vSphere, including scheduled enforcement of VM resource-allocation policies.
