About

Five years in web development and data (backends in Node.js, pipelines in Python, React front ends), and the last year on-chain, writing Soroban contracts in Rust.

Currently CTO at Plina Finance, building on-chain infrastructure for institutional tokenization of credit rights; the only engineer on Yalla (contracts, backend, front end, design and infrastructure), an on-chain ticketing platform already running real events in Brazil; and founder of Karn, an open-source governance ecosystem on Stellar.
