Reliability at scale
10,000+ servers and 400,000+ cloud assets across AWS, Azure, GCP and Alibaba — kept observable, kept honest.

Reliable systems. At scale. On purpose.
I've spent five years keeping production systems calm — across cloud, containers, and observability. My focus is the unglamorous work that makes everything else possible: automating the toil, owning the incident, and shipping the runbook.

> about
What I optimize for.
Four pillars I keep returning to — the lens I use to evaluate a system, a process, or my own work.
02
Automation & efficiency
Terraform, GitLab CI, Helm, Chef. If a human is doing it twice, I'd rather write the script before the third time never gets done.
03
Observability & response
Operated five enterprise platforms (Datadog, Dynatrace, Zabbix, Site24x7, PagerDuty). Escalation point for critical incidents, with RCA ownership.
04
Operational excellence
I work the seam between engineering and ops — translating customer pain into platform improvements, and process changes that actually stick.
