Applied AI Engineering Portfolio

Building reliable, evidence-driven AI systems for real engineering workflows.

A collection of production-minded AI systems focused on reliability, evaluation, security, incident response, and DevOps decision support.

What I Build

Production systems that go beyond demos and prototypes

RAG systems with grounded answers and citations

Enterprise-grade retrieval-augmented generation with strict mode for safety

Automated LLM evaluation and regression testing

Catch regressions before they reach production with comprehensive test suites

Secure AI gateways with guardrails and cost controls

Rate limiting, PII redaction, prompt injection detection, and cost tracking

CI/CD pipelines for AI systems

Automated testing and deployment workflows for reliable AI delivery
