Software engineer living in San Francisco. I've worked on ML systems at Uber, interfaces for language models at Perplexity, and performance simulations for some of the largest solar plants in the US.
In 2022 I left my job to learn how to build products fullstack - design, engineering, marketing, and sales. Highlights have been an LLM playground (top 10 on Product Hunt), a growing app for SF residents to simplify parking (featured on ABC news), and building an engineering community around the future of American manufacturing.
In my free time I enjoy reading - lately bios of great adventurers and US history. I'm a regular open water swimmer in the bay.
