I'm Brian Teller. I've spent 25 years building, breaking, and fixing infrastructure at startups and enterprises. Now I help engineers skip the painful lessons I had to learn the hard way.
I focus on patterns that actually work in production, not theoretical concepts that fall apart when pagers start going off.
Stuck on a migration? Drowning in Terraform spaghetti? Let's work through your specific challenges together. I've seen most of these problems before β and I know where the landmines are buried.
Get your team aligned on infrastructure best practices, incident response, or platform strategy. Interactive sessions focused on the tools and patterns you're actually using.
Step-by-step progression from foundational skills to advanced platform engineering. Hands-on labs, real-world scenarios, and none of the "hello world" demos that crumble in production.
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.
I've watched too many talented engineers waste years learning things the hard way. My goal is to compress that timeline: help 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, I've got you covered.
Master the core skills every infrastructure engineer needs. No hand-waving β just practical patterns you'll use daily.
Learn to keep systems running β and to sleep through the night. Reliability isn't magic; it's discipline and the right practices.
Design internal developer platforms that scale with your org. Build golden paths that developers actually want to use.
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.
I'm not a generalist pretending to know everything. Here's where I go deep.
Terraform, Terragrunt, modular patterns that don't become unmaintainable. I've seen IaC done wrong more times than I 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. I live in k8s.
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.
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're trying to land your first DevOps role, get unstuck on a gnarly migration, or build a platform engineering practice from scratch, I'm happy to chat about how I can help.
