Build & learn in public

Teller's Tech Labs

Experiments, prototypes, and learning systems for helping engineers build real operational judgment — not just collect tools.

AI-Driven Learning Production Scenarios Operational Judgment Build in Public Incident Reasoning

Code Duck

Practice production judgment without breaking production.

An AI-driven production incident simulator for DevOps, SRE, cloud, and platform engineers. Instead of memorizing commands or clicking through multiple-choice labs, learners work through realistic incidents in natural language — investigating, hypothesizing, and choosing safe next steps.

  • Realistic production-style scenarios
  • Conversational, non-linear investigation
  • Coaching feedback on reasoning, not just answers
  • Built around the way engineers actually debug

Platform Foundations

Hands-on Terraform / CI/CD / AWS / EKS training.

A future practical training track around Terraform, Terragrunt, GitHub Actions, AWS, and EKS — with an opinionated starter repo. Currently paused while Teller’s Tech focuses on Code Duck, advisory, workshops, and speaking work.

  • State bootstrapping (S3 / DynamoDB)
  • Environment structure & promotion
  • CI guardrails (plan/apply gating)
  • Production EKS with sane defaults

Future Labs

Where the thesis grows next.

Code Duck is the first lab. Future experiments under consideration build on the same belief: that operational judgment is the underrated skill in modern infrastructure work.

  • Postmortem reasoning exercises
  • Architecture review scenarios
  • AI governance & agent-risk labs
  • Reliability decision simulations

Why "Labs" and not "Courses"

Most DevOps training overvalues command recall and undervalues operational reasoning. Labs is where Teller’s Tech builds and tests the systems that try to fix that — starting with Code Duck and the belief that better infrastructure starts with better operational judgment.
