Teller's Tech Labs
Experiments, prototypes, and learning systems for helping engineers build real operational judgment — not just collect tools.
Lab projects
Code Duck
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
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
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.
