My name is Derui (Derek) Wang.
I graduated from UC Berkeley in 2023, where I triple majored in Computer Science, Data Science, and Economics.
I make LLM agents reliable enough to ship in regulated domains.
At Double Blind Bio I'm a founding engineer on DeBBy — an AI agent that automates clinical-trial discovery, site feasibility, and sponsor outreach — and I own our AI evals & observability program end to end.
Before this: KYB risk-scoring and a LangGraph/DSPy business-intelligence agent at Baselayer (fintech), and ~20 months as an independent founder prototyping digital-health tools for psychedelic-assisted therapy and ADHD support — where I learned I wanted production engineering depth before building a company.
The through-line: taking ambiguous, high-stakes workflows end to end and making the AI measurable, debuggable, and appropriately controlled. Evaluation is the part I care most about — the systems that tell you whether a model is actually right, not just fluent.
