At Cupola Labs, I own the architecture and delivery of Relic and Wrapper, from backend systems and APIs to CLI, web, and documentation. Relic is an open-source encrypted secrets manager for developers and AI agents; I built its CLI, React TUI, and Rust runner, and it has earned 200+ GitHub stars.

I also built Wrapper, which streams live terminal sessions from AI coding tools to an iOS viewer. Previously, I led six engineers at Metatime across DEXs, DeFi protocols, and a custom EVM-compatible blockchain, and worked on Solidity contracts at Metavault and backend services at Marti Technologies.
