About Me

I'm a full-stack AI/ML engineer and creative technologist specializing in intelligent systems, data analysis, and digital fabrication. With expertise spanning from advanced AI agent architectures to precision laser engraving and CNC machining, I bridge the gap between software engineering and physical making.

My work focuses on building production-ready AI applications, automating creative workflows, and developing specialized tools for digital fabrication. I combine deep technical knowledge with practical engineering to create systems that solve real-world problems.

Featured Projects

AI Crew Stack v2

Production-ready personal data analysis framework with RAG-powered insights. Processes emails, browser history, and purchases to generate unified intelligence profiles. Features FastAPI backend, multi-source analyzers, and LLM integration (OpenRouter, Perplexity, Ollama).

Stack: Python, FastAPI, ChromaDB, PostgreSQL, LangChain

MOPA Laser Toolkit

Unified toolkit for generating LightBurn projects for advanced MOPA fiber laser effects. Automates diffraction gratings (holographic effects), stainless steel color marking, and 3D embossing. Production-ready with comprehensive testing and safety documentation.

Hardware: Cloudray GM100 60W JPT M7 MOPA

Cloud Infrastructure

Modern AWS infrastructure using Terraform for static site hosting with CloudFront CDN, private S3 origins via OAC, automated CI/CD with GitHub Actions OIDC, and comprehensive security. Powers multiple production domains with minimal cost (~$2-3/month).

Stack: Terraform, AWS (S3, CloudFront, Route 53, ACM, IAM), GitHub Actions

Specialized AI Services

Collection of AI-powered services including tarot reading API (Golden Dawn tradition), astrology birth chart calculator (real ephemeris data), and wisdom RAG (18 ebook knowledge base). Built with FastAPI, LangChain, and local LLM inference.

Stack: FastAPI, LangChain, Ollama, ChromaDB, Python
