Lead Infrastructure Engineer with 20+ years in IT (10+ of those in financial technology). I administer and support the full stack behind a real-time index platform tracking $3T+ in indexed assets: Windows and Linux servers, VMware, storage, ssl cert renewal, automation, SQL Server, the CI/CD pipeline (GitHub Cloud with self-hosted TeamCity and Octopus Deploy). The platform runs with no unplanned outages during business hours and trading days. I manage four environments across two data centers, 125+ VMs, and 47 SQL Server instances, handling release deployments, performance tuning, troubleshooting, and the ongoing upgrade cycle for 20+ applications and appliances, all without disrupting production. I take on large projects end-to-end: recently designed an automated process for SQL downgrade project, created and tested sql and powershell scripts, created and executed the project plan for the downgrade of 45 SQL Servers from Enterprise -> Developer/Standard for $1.75M license savings. Worked with developers to reduce the core index database by 51% for 4x faster processing and storage savings; and led our Bitbucket-to-GitHub migration. MBA, MCSE, CCNA.
