# Len Huang > Software Engineer @ Adonis Location: Brooklyn, New York, United States Profile: https://flows.cv/lenhuang I’m Len, a software engineer focused on building products end-to-end and applying AI at the application layer. • At Adonis, a Series C health tech company, I build durable agentic backend tools to automate complex workflows across Electronic Health Records, payer portals, and more. • At StubHub, leading up to the IPO, I owned the ideation, experimentation, implementation, and analysis of hundreds of conversion-driving A/B tests affecting millions of users in the checkout flow. • Outside of work, I've been exploring a few AI-driven applications, like Duolingo for Leetcode and also ESPN-style commentary on audio clips from my group chat.
