About

What I Do

14+ years shipping production software in lean and fast-moving environments. Currently the de facto engineering lead across 10+ live SaaS products at a product studio - covering full-stack development, DevOps, and AI integrations simultaneously.

Built HFCM (600,000+ active WordPress installs), a multi-layer AI matching pipeline (embeddings, vector search, Ollama/Qwen2.5, OpenAI), and multiple SaaS tools with paying subscribers - all from scratch.

Multi-LLM experience across OpenAI, Claude, Perplexity, Ollama, and Dify. Comfortable leading teams or operating autonomously, and equally at home defining architecture as shipping code.
