Database Administrator · Reliability Engineer
Make data
stay ready.
I design and operate dependable database environments where performance, recoverability and observability are treated as one system. From query plans to failover drills, I turn noisy data infrastructure into calm, measurable operations.

01 / Profile
Operations with
an observability mindset.
My work lives at the intersection of database internals, infrastructure automation and production reliability. I favor repeatable runbooks, useful telemetry and boringly successful recovery tests.

High availability
Replication topologies and controlled failover patterns designed around realistic recovery objectives.
HARPO/RTODR
Automation & observability
Runbooks become scripts, scripts become repeatable systems, and metrics make their outcomes visible.

03 / Selected work
Systems that
earned their calm.
Case-study snapshots focused on outcomes, operational thinking and the mechanics behind resilient data platforms.
Moved a revenue database without moving the business clock.
Designed staged replication, validation gates and a rehearsed cutover path for a multi-terabyte PostgreSQL estate. The migration became a controlled sequence instead of a midnight gamble.
POSTGRESQLCDCCUTOVER
Reduced p95 latency by 71%.
Traced lock contention and plan regression to a small set of high-impact workloads.
QUERY PLANSP95
Made restore confidence measurable.
Turned backup checks into recurring recovery exercises with evidence, timing and ownership.
PITRDR
04 / Journey
From tickets
to systems thinking.
A DBA career arc centered on production responsibility and progressively broader infrastructure ownership.
Platform Reliability / Data Operations
Own database reliability standards, migration patterns, capacity planning, incident response and recovery exercises across business-critical workloads.
Cloud Database Engineering
Modernized legacy estates, introduced automated provisioning and built observability around replication, storage and query performance.
Production Infrastructure
Managed backups, patching, performance diagnostics, access controls and operational support for high-volume transactional systems.
