About
I'm a 20-year-old design engineer, working on FLORA — the first agentic creative tool with fine-grained control over AI.
I'm on leave from USC Iovine and Young Academy (<40 students/year, on scholarship), where I researched AI, design, and cryptography.

Work
I previously founded Mainstream Labs, backed by $1.2M from Lemniscap, Samsung, and angels from Reverie, Coinbase, and many more to reimagine how people interact with crypto.
Through an independent design practice, I collaborate with clients such as Exa, Endaoment, Google X, and more. If you’re interested in working together, please reach out via email or X.

Investing
I'm an investor and advisor in a small number of early-stage startups, with a strong bias toward exceptional founders. I'm most helpful on product and design, where my instincts are sharpest.
