Summary

Senior🎓
Top SchoolAlex Choi is a Generative AI Engineer and founder with 11 years of experience building production-grade AI systems end-to-end, from mobile apps to large-scale recommendation platforms. An early engineer at WeWork (one of the first 15), he launched the company’s first recommendations MVP in a single quarter, driving a 15% engagement lift and later scaling it into a platform used across products. He’s led teams and rebuilt customer-facing systems—most notably a high-rated real-time transcription app—and now focuses on generative agents and ML products, including a self-optimizing ReAct agent that outperforms published GAIA baselines at 4x lower cost and KiraHeadshots.com. Comfortable across the stack (Next.js, FastAPI, AWS/Azure, Redshift, Airflow) and grounded in cognitive science, he blends product-minded engineering with practical research to ship impactful, cost-efficient AI features.
