What I built

  • Kubernetes-native eval pipeline (FastAPI → RabbitMQ → Kaniko → isolated GKE jobs) with NetworkPolicy egress lockdown for running untrusted code safely.
  • An AEMO-calibrated energy-market simulation engine (battery wear, FCAS, carbon pricing, noisy forecasts), published to PyPI with CI auto-release.
  • Adversarial scenario design (false-data injection, an LLM-vs-regex compliance trap) with a state-leakage contract test that hides ground truth from competitors.
