I'm Stephen, an AI & Machine Learning Engineer building end-to-end systems that turn raw data, documents, and user questions into reliable AI experiences.

My work sits at the intersection of machine learning, product thinking, and full‑stack engineering. I design retrieval pipelines, evaluate embeddings and prompting strategies, build RAG systems, and ship polished interfaces that make those models useful in the real world.

I've built and shipped AI-powered products across document understanding, retrieval, and workflow automation, and I enjoy solving the hard parts of real-world ML systems: benchmarking model behavior, improving grounding, and translating technical complexity into dependable product experiences.

I've collaborated with major infrastructure companies like Extern on advanced product and AI engineering work. From architecture to implementation and iteration, I enjoy shipping systems that balance performance, usability, and business impact.

I'm also actively building in public. Connecting with my 230+ followers on X and learning from top mentors in the space—including @Marc Lou, @johnrushx, @tdinh_me, and @levelsio—has shaped how I think about building AI products and shipping fast with strong fundamentals.

I also love music and play both a keyboard and a drum.
