At the Ethereum Foundation, I worked on ethereum.org and led its full Gatsby-to-Next.js migration, defining site architecture and rewriting core logic. I also improved the Find Wallet experience and built the Learning Quizzes hub.

I replaced the EF Blog’s Jekyll stack with native i18n support, and led rebuilds of the Geth website and Ecosystem Support Program site. That work included improving documentation UX, adding built-in search, and integrating APIs.

As a freelance software engineer, I develop modern full-stack web applications with a focus on frontend engineering, maintainable code, and user experience. Before that, I contributed to Seed Advisor and its GraphQL middleware at climate.com | TradeHelm, Inc.

I founded an open-source school for Full Stack JavaScript training and co-founded the Buenos Aires freeCodeCamp chapter. I’ve also developed learning materials and platforms, mentored students, and built web and mobile solutions for clients.
