Production engineer, 25+ years in production. I run systems, write about running them, and build tools for the people on call. More about me at BrianTeller.com.

🎖️ DevOps Institute Ambassador · ITIL Ambassador · Industry Advisor at Cornell Tech, mentoring a multidisciplinary team of master's students through Studio — technical feasibility, engineering tradeoffs, reliability, and what it actually takes to get an idea into production.

All live, all free unless noted. Home base is TellersTech.com (also tellerstech.io).

Publications

• 📰 OnCallBrief.com — a weekly SRE/DevOps brief, curated from 265 sources. What happened, and what it means for the team that has to run it afterward.
• 🎙️ ShipItWeekly.fm — a weekly podcast on shipping and operating production systems. 60+ episodes, also on Substack. (also shipitweekly.io)
• 📖 Confidently Wrong — AI for DevOps & SRE Engineers. In development, active draft. AI treated as what it actually is in production: an untrusted system with real authority and a real blast radius.
• 🎧 Best DevOps & SRE Podcasts — a listening guide, updated as the field moves.

Tools & labs — tellerstech.com/labs

• 🦆 CodeDuck.ai — a terminal CLI that runs incident scenarios, so on-call practice doesn't have to be a real outage. (also codeduck.io)
• 🛰️ Beacon Command — a browser game that teaches SRE and DevOps concepts through a space-station sim.
• 🔗 tsn.io and ysn.io — two link shorteners on one codebase, split by whose links they carry. tsn.io mints everything I publish; ysn.io carries other people's, by invitation. Neither trusts the caller and the destination at once.

Awards

• 🏆 LMGT.org — free, vendor-neutral awards for knowledge given away in production engineering. No fees, no categories you can buy. (also DevOpsAwards.com, DevOpsAwards.org)

Working with me

• 🧭 Advisory · Workshops · Speaking · 1:1 Mentorship
• 🏗️ WBAT.net — infrastructure consulting: IaC with Terraform, and the platform work around it.

And one that is purely a joke

• 🙃 LMGT.com — "let me google that". Not the awards; the naming misleads on purpose.

Co-led large-scale AWS → GCP migrations. Owned Kafka platform engineering through vendor transitions (Confluent Cloud → MSK → Confluent Cloud with private networking), including Schema Registry and MirrorMaker2/Replicator during cutover windows. Ran SOC 2 evidence programs across multiple audit cycles, supported public-company readiness and SOX preparation, and contributed to PCI programs in HIPAA-certified environments. Led disaster recovery with explicit RTO/RPO targets. As CTO of a digital-signage company, led a zero-downtime migration to the cloud.

Day to day: Terraform and Terragrunt, AWS, Kubernetes and EKS, Kafka, CI/CD, GitHub, incident response, infrastructure guardrails, cost management, and the messy operational details that never show up in clean conference demos.

Before infrastructure, radio — college station, a major-market DC morning show, then evenings on Key 103.1. Live timing, reading a room, and staying composed when things break on air.

Most of my day-to-day lives in private repos, so the cards below count a fraction of the work.
