AI
AI-native builder for 4 years and child-safety contributor. I ship with the knowledge base that I have been consistently growing over the past years.
03
Finance
DCF, LBO, and modeling. Alongside Microfinance at Berkeley & the Private Equity club, I create data pipelines that cut busywork and impact real businesses.
TLDR
I'm an early-career, AI-native builder working fast and across disciplines. I turn mathematics into models, ideas into shipped sites, and messy data into confident business decisions. Curious, self-directed, and pragmatic about getting real things done.

AI Engineer @ BrightAI · UCSB Alum
Senior teammate on my BrightAI computer-vision project
Arthur and I worked on the same computer vision project at BrightAI, and I was consistently impressed by his work ethic and his ability to contribute meaningful work from early on. He was usually the first one in the office and often one of the last to leave. He took the work seriously and had a functioning model up soon after joining the team, and he also handled integrating other interns' work into the client-facing side of the project. Arthur delivers quality work at an engineer-level pace and he is an overall pleasure to work with.
