More About Me
01 Oracle Database

Oracle Database

DBA · RAC · Data Guard · Performance · Migrations

With 30+ years managing Oracle production environments — from Oracle 7 through 21c — I bring the depth of someone who has seen most of it and fixed all of it. Mission-critical OLTP systems, Exadata data warehouses, six-nines availability requirements.

02 SQL Server & Azure

SQL Server & Azure

Architecture · Always On · Azure SQL · Replication

From on-premises SQL Server 2008 to Azure SQL Managed Instance, I design, migrate, and operate SQL Server environments that are resilient, secure, and fast. My specialty is Always On Availability Groups — including the edge cases documentation doesn't cover.

Automation · APIs · Data Pipelines · AI Tooling

I build Python tools that live between the database and the business — ETL pipelines, monitoring agents, REST APIs over Oracle and SQL Server schemas, and AI components that read execution plans and respond to natural-language DBA queries.

05 Performance Engineering

Performance Engineering

Query Optimisation · Indexing · Execution Plans · Profiling

Performance problems are almost always solvable — if you know where to look. I read execution plans the way others read spreadsheets, and I've turned 45-minute queries into sub-second ones more times than I can count.
