Zachary Roth

Founder & Product Engineer @ Raintree

I build reliable software across AI, developer tools, and data-intensive SaaS. My work focuses on trustworthy context, scoped data access, human approvals, and auditable execution.

Who am I?

At Raintree Technology, I design and ship full-stack products primarily using TypeScript, Python, Rust, and Postgres.

Previously, I worked across developer relations, ecosystem growth, and product teams at Aptos Labs. Earlier, I managed product work for Solflare during its growth to 500K users and authored investment and technical materials supporting more than $2B in private-market fundraising initiatives.
