Database administration isn't just what I do — it's where I excel.
With 4+ years driving high availability, disaster recovery, and performance tuning across enterprise SQL Server environments, I've become the go-to expert others turn to when systems can't afford to fail. I don't just keep databases running — I make them bulletproof.
I've spent the last 4+ years mastering what most DBAs merely maintain: uptime, speed, and resilience.
As a Subject Matter Expert in the SQL Server world, I've built my reputation on solving the problems other admins escalate — diagnosing blocking chains in seconds, architecting AlwaysOn Availability Groups that don't just meet SLAs but redefine them, and turning sluggish, poorly-indexed databases into high-performance systems that businesses can actually rely on.
My expertise runs deep across high availability (AlwaysOn, log shipping, replication), disaster recovery strategy, and performance tuning — the kind of work that separates a database administrator from a database expert.
Today, I'm shaping the next generation of DBAs, training talent at NSTAR Technologies. Before that, I served as Principal DBA at Excella Services, a key part of AB InBev, where I owned mission-critical infrastructure others depended on.
