React Native

A framework for building native apps using React.

React Native enables building native mobile applications using JavaScript and React, providing a bridge to native components while maintaining a single codebase.

It offers near-native performance with hot reloading for faster development cycles and access to device-specific APIs and capabilities.

Experience:

Developed a multimodal AI assistant with voice and chat interfaces for LegalAgent's mobile app using React Native and Expo.

Integrated OpenAI's Realtime API for voice transcription and synthesis in a bilingual legal assistant application.

Enhanced Sense.chat's performance and integrated EOS blockchain for secure encrypted communications and token functionality.

Built the first version of Wink, Costa Rica's first neo-bank mobile app, with React Native and biometric authentication.

Implemented augmented reality features for Tractor Supply mobile app using ViroAR for interactive product previews.

LegalAgent

AI assistant with both voice and chat capabilities into LegalAgent's React Native (Expo) mobile app. This assistant empowers lawyers to swiftly access case information, providing contextual legal support, document summaries, and procedural guidance.

Make Sense Labs

Sense.chat, developed by Sense/Make Sense Labs (backed by Tim Draper and other notable investors), was one of the first crypto messaging apps to implement self-sovereign identity and encrypted communications on blockchain. The app gained recognition at major tech conferences and blockchain events. My role at Sense involved enhancing the React Native app's performance and integrating it with the EOS mainnet for secure messaging and token functionality.

Knowledge.io

Knowledge.io was one of the first blockchain platforms aimed at knowledge-sharing with a token-based reward system. The project successfully completed its ICO in 2018, raising funds to build a decentralized knowledge ecosystem that included partnerships with advertising networks to monetize user expertise. My role at Knowledge included leading the architecture of the Ethereum-based token and supporting systems for their successful ICO, and forming a skilled development team across three countries.

Wink

Wink, Costa Rica's first neo-bank, offers a mobile app for online banking, eliminating the need for physical branch visits. I developed the first version of Wink's mobile app and backend services within AWS. My role involved API integration with partner banks and forming a dedicated development team.

Tractor Supply

Tractor Supply Company, a Fortune 500 company with over 2,000 stores and $10B+ in annual revenue, is America's largest rural lifestyle retailer. Their mobile app serves millions of customers with features like product browsing, exclusive offers, account management, and augmented reality product previews. As a consultant, I enhanced the app's performance and code quality, and developed its augmented reality feature, improving user experience and engagement.
