Apply current LLM patterns (RAG, retrieval, routing, tool‑use, evals) to deliver measurable customer value—faster, more reliable AI systems; reduced time‑to‑decision; improved trust / safety metrics; and lower cost per query.

Lead by example through writing high‑quality, maintainable code that demonstrates engineering craftsmanship.
