Summary
🤩
Rockstar🎓
Top SchoolDon Seiler is a Staff Engineer and seasoned DBA with over 15 years of hands-on experience and a 20+-year background in Oracle and PostgreSQL ecosystems, now focusing on cloud infrastructure (GCP & Azure) and automation. He designs and operates high-availability Postgres platforms using tools like Patroni, pgBackRest, HAProxy, Terraform, Ansible and Chef, and has built repeatable, IaC-driven deployment processes for production and DR. At Jack Henry he blends deep database tuning and backup/restore expertise with cloud-native architecture, migration and provisioning work. A longtime open-source enthusiast and certified GCP cloud architect, he pairs pragmatic scripting (bash, ksh, Python, Perl) with team leadership from prior DBA manager roles. Based in Manitowoc, WI, he’s equally comfortable debugging complex storage/replication issues as coaching youth hockey — a hint at steady, team-first temperament off the clock.
