01 / Selected work

Systems built from messy data to measurable outcomes.

From 56,000-page search corpora to 2TB video pipelines, each project turns a hard engineering problem into a result that can be measured.

02 / Experience

AI delivery, from ambiguity to production.

I work across the delivery loop: requirement discovery, AI system design, integration, evaluation, interface, and cloud deployment.

AI Forward-Deployed Engineer

JC Pacific Corp · Irvine, CA

Translated real-estate workflows into deployable AI systems: a RAG assistant designed for roughly 800 active listings, a GPT + DocuSign contract POC, and an evaluation suite spanning 300 RAG questions, 50 contracts, and 200 multi-turn conversations.

AIGC Application Engineer Intern

Vision X · San Jose, CA

Delivered an end-to-end advertising workflow that paired GPT copy generation with Midjourney visuals, then built a reusable prompt evaluation, component, and data-model foundation that reduced average AI feature development time by about 33%.

03 / About

Equal parts logic and curiosity.

I earned a B.S. in Computer Science from UC Irvine and now build applied AI systems across retrieval, evaluation, and full-stack delivery.

I am strongest where the requirements are still fuzzy: turning business context into a testable technical plan, connecting models to real data and workflows, and defining the metrics that tell us whether the system is ready.
