Know the data, solve what breaks, build the system that keeps it working. Day to day that is a slow query, a stalled replica, a job that did not run. Find the cause, fix it, then write the check or the script so it does not come back.
Twenty-odd years running databases came first – Oracle, MySQL, PostgreSQL, MongoDB, Redis. Different engines, same trade-offs: consistency, latency, cost, and the failure modes nobody documents. When production breaks, I look at the data layer first; that is where the answer usually is.
Industrial Engineering by training – automation and control systems. Feedback loops and process control turned out to be a good model for infrastructure: systems that correct themselves and don’t need someone watching.

How I Work #
Everything as code, everything reviewed. Small changes, shipped through CI/CD, easy to reverse.
I measure what the business feels – throughput, freshness, error rates – and alert on that. Well-chosen SLIs catch problems before users do.
Cloud spend is an operational metric I own, not a finance afterthought. Most performance problems I have seen came down to indexing or data modeling, not more hardware.
Compliance is engineering discipline, not paperwork. SOC2, GDPR, and PCI DSS have all gone through my hands, and the controls that pass an audit are the same ones that make a system safer to operate.
A well-built platform shouldn’t need heroes. Common failures fix themselves, documentation covers the rest, and every significant incident ends in a blameless postmortem. I have been on call long enough to prefer it that way.
Reproduce, isolate, fix, document. Reading about a failure mode is not the same as having triggered it yourself.
