My journey

At American Express, I worked on credit-card interfaces from 2010 to 2012, building interactive comparison tools and responsive landing pages, working with analytics and A/B testing, and helping move an older frontend toward modern JavaScript.

From 2012, I also helped organize Costa Rica JS. Through meetups, NodeSchool, and Front End Day, it grew into a community of more than 2,000 developers.

Wink changed the scale of my work. Costa Rica's first neobank was designed to make banking accessible from a phone, without visiting a branch. I joined as Lead Engineer in 2015 and built the first React Native application and AWS backend, integrated partner-bank APIs, and implemented biometric authentication through a native bridge.

Bringing Wink to launch meant more than writing code. I helped choose the technology, coordinate partners and vendors, plan delivery, and build the engineering team.

Building financial products led me toward blockchain infrastructure and the interfaces around it. From 2017 onward, I worked on tokens, marketplaces, and networks, including Knowledge's ERC-20 token, AsoBlockchain, which I co-founded, and EOS Costa Rica, where I helped launch the EOS mainnet and worked on a private chain for the innovation labs of a global accounting and consulting firm.

The work later moved closer to everyday product experiences: Bitcash's exchange and browser signing, ChainGraph's blockchain data tools, RareMint's marketplace, ZTX's in-world wallet, Bitlauncher's auctions, and Opyn's trading interface.
