Experience

1. Senior Software Engineer

   Aurora

   Mar 2025 — Present · Pittsburgh, PA, US

   Principal contributor for the Logset Service, managing end-to-end data curation for petabyte-scale AWS S3 logs; engineered hierarchical data structures to orchestrate storage tiering, data protection, and automated purging/restoration logic. Spearheaded the Log Thawing service to automate S3 log rehydration from cold storage; architected a staged pipeline that decouples metadata discovery from S3 batch submission via a manual triage checkpoint, preventing redundant restorations and optimizing cloud expenditure. Led full-stack ownership of the Log Thawing service, developing robust API/CLI functions and improving user workflows while resolving concurrency deadlocks and optimizing database performance via strategic indexing. Designed a robust, self-healing cron job system for the Log Thawing service to automate database table maintenance, featuring automatic restart and failover mechanisms to ensure platform health. Engineered high-performance functions for the core library to optimize log file discovery via S3 ListPages API orchestration and established scheduled Buildkite CI/CD pipelines integrated with Grafana and Slack. Modernized the observability stack by migrating legacy Opsgenie alerting to a Grafana/Slack metrics-driven system, enabling the retirement of legacy infrastructure.
