Skills Flexed

  • Azure OpenAI prompt engineering with JSON schema responses
  • Next.js 15 App Router UI + accessibility-first interactions
  • Adaptive learning logic: diagnostics, drift control, and retry flows
  • PromptOps harness for regression testing evaluation suites

Idea

I open-sourced the tooling I use to keep GenAI systems from drifting. PromptOps Lab packages experiment orchestration, baselining, and regression alerts into a single CLI plus dashboard.

Capabilities

  • Scenario packs · YAML-driven suites that mix golden answers, adversarial prompts, and load spikes.
  • Multi-model diffing · Compare OpenAI, Azure, local Ollama models, and custom fine-tunes in one run with automatic cost/time tallies.
  • Guardrail checks · Built-in assertions for tone, compliance, PII, and hallucination risk - plug in custom checkers via a simple interface.
  • Reporting · Generates Markdown dossiers with charts, failure heatmaps, and recommended prompt tweaks.

Why I built it

  • Clients kept asking “did we regress?” after a prompt tweak - this keeps the answer objective.
  • Makes onboarding new teammates simple: run promptops suite onboarding.yaml and you get instant baselines.
  • Integrates with CI (GitHub Actions + Azure DevOps) so every PR ships with evaluation diffs.
