Danny Goldstein is a software engineer with 13 years of experience who transitioned from an academic career in astrophysics (PhD, Berkeley) and a NASA Hubble Fellowship into building developer tools and core product features for ML systems. After roles at Berkeley Lab and progressive engineering positions at Weights & Biases—through its acquisition—he now contributes to ChatGPT core product engineering as a Member of Technical Staff at OpenAI in New York. He combines rigorous scientific thinking with production-grade software design, focusing on scalable, developer-friendly ML tooling and platform services. Not obvious from titles alone: his background in physics and independent research fellowship informs a data-driven, hypothesis-led approach to debugging and feature design that helps bridge research and product.
