Teller's Tech is a training platform for DevOps and platform engineering, founded by Brian Teller. 25 years of production experience distilled into practical workshops, courses, and coaching.
Patterns that work in production, not theoretical concepts that fall apart when pagers start going off.
Our flagship course. Terraform + Terragrunt + GitHub Actions + AWS + EKS. Get an opinionated starter repo and hands-on training to build production infrastructure the right way. From $149 (individuals) / $7,500+ (teams)
Stuck on a migration? Drowning in Terraform spaghetti? Work through your specific challenges with an experienced engineer who's seen most of these problems before.
Get your team aligned on infrastructure best practices. Interactive sessions focused on Platform Foundations or custom topics for your org. Delivered on weekends or scheduled dates.
The best infrastructure engineers don't just write code. They build systems that make entire teams more effective. Companies need people who can bridge development and operations, and there aren't enough of us to go around.
Too many talented engineers waste years learning things the hard way. Teller's Tech was built to compress that timeline: helping you avoid the midnight pages, the migration disasters, and the "why didn't anyone tell me this?" moments.
Whether you're just getting started or ready to architect platforms at scale, we've got you covered.
Terraform + Terragrunt + GitHub Actions + AWS + EKS
Build production-ready infrastructure the right way. Get an opinionated starter repo, hands-on training, and a deployed EKS cluster with sane defaults.

Learn More →A new way to learn DevOps that focuses on thinking like an engineer first, not memorizing tools. Code Duck uses adaptive assessments, targeted explanations, and practical challenges to build real understanding and confidence in core DevOps reasoning. Focused on Terraform to start.
Foundational learning designed to give you the mental models and system thinking most companies actually test for. Before tools and syntax, you'll get grounding in how systems behave, how automation works, and how to reason about production-scale problems.
A deeper progression built for people ready to go beyond basics into real-world engineering judgment. Mastery covers advanced workflows, reliability patterns, scaling practices, and end-to-end automation decisions, blending concept with real application.
The DevOps, SRE, and Platform Engineering News Podcast
Every week, I break down what actually matters in DevOps, SRE, and platform engineering. Outages, releases, tools, incident writeups, all translated into lessons you can use. Most episodes run 10-25 minutes. No fluff, just practical takes.
Catch up on every episode of Ship It Weekly
No generalist fluff—just deep expertise from real production systems.
Terraform, Terragrunt, modular patterns that don't become unmaintainable. We've seen IaC done wrong more times than we can count.
EKS, EC2, IAM, GKE, Cloud Run. Not just "pass the cert" knowledge. Production experience at scale across both major clouds.
GitHub Actions, automated pipelines, deployments that don't require crossing your fingers.
Container orchestration from "what is a pod?" to running multi-tenant platforms. Production-tested in EKS and GKE.
Metrics, logs, traces, and more importantly: knowing what to actually look at when things break.
Error budgets, runbooks, postmortems. How to build systems that fail gracefully and teams that respond well.
MSK and Confluent, plus Strimzi on Kubernetes. Migrations (MM2/Replicator), partition rebalancing, connector ops, and keeping pipelines stable through broker pressure and outages.
Brian taught me DevOps practices and helped improve and speed up our deployments for our earth station in-orbit test systems.
Teller's Tech helped get our CI/CD in order and streamlined our deployments for our SaaS platform.
Brian helped migrate us to AWS from on-prem while keeping the system up. Awesome experience!
Whether you want to get Platform Foundations for yourself or your team, need help with a gnarly migration, or want to build a platform engineering practice from scratch, let's talk.
