Gabo Esquivel - React Native & Mobile Development Experience

With over 15 years in full-stack software engineering, I help organizations turn initial ideas into market-ready software products, ensuring concepts reach their full potential. I work as a product engineer, bridging technical execution with user experience and business strategy.

My mobile development work focuses on creating cross-platform applications with React Native. As someone with extensive experience in frontend development and fullstack architecture , I'm passionate about mobile-first experiences that feel native while leveraging the efficiency of cross-platform development. My approach emphasizes performance optimization, intuitive interfaces, and seamless integration with device capabilities and backend services.

Banking & Fintech Mobile

I started mobile development with Wink, Costa Rica's first mobile neobank. I implemented React Native bridges for biometric authentication, creating a secure yet user-friendly banking experience. This project required deep integration with native device capabilities for secure biometric verification while maintaining a seamless cross-platform experience. The application enabled users to complete banking tasks entirely from their mobile devices, eliminating traditional branch visits.

Secure Messaging: Sense Chat

At Sense Chat, I helped develop a secure React Native messaging application with integrated EOS wallet functionality and token-based incentives. This app combined encrypted communication channels with blockchain wallet capabilities, allowing users to exchange messages and cryptocurrency in a single interface. The implementation required careful attention to security, offline capabilities, and seamless wallet integration—all while maintaining a clean, intuitive UI that made complex blockchain interactions accessible to mainstream users.

Augmented Reality: Tractor Supply

For Tractor Supply, I worked on augmented reality product previews in React Native. This feature allowed customers to visualize products in their real-world environment before purchasing, significantly enhancing the shopping experience for large outdoor equipment. The implementation used React Native's AR capabilities combined with 3D product models and real-time rendering, optimized for performance across device types. Like my other mobile projects , this work demonstrated how mobile applications can bridge digital commerce with physical reality through immersive experiences.

Fantasy Top Shots Blockchain Gaming

With Fantasy Top Shots, I built an Expo-based mobile game that integrates Flow blockchain NFTs into a fantasy sports experience. The application combines real-time sports data with blockchain collectibles, allowing users to build lineups with their owned NFTs. The implementation used Expo for rapid cross-platform deployment while integrating Flow blockchain for secure NFT ownership verification. This project explored new gaming models at the intersection of mobile, blockchain, and fantasy sports.

AI Assistant: Sfera Legal

Most recently, at Sfera Legal, I developed a React Native application featuring an advanced AI assistant with voice and chat capabilities. This mobile app helps legal professionals access and understand complex documentation through natural language interactions. The implementation combines React Native's cross-platform efficiency with cutting-edge AI technologies , including voice recognition, natural language processing, and retrieval-augmented generation. The result is a powerful mobile tool that accelerates legal work by reducing research friction and providing contextual insights.

This project represents the exciting future of mobile development—where intelligent interfaces adapt to user needs and provide contextual assistance through natural interactions. The combination of voice, chat, and AI capabilities creates a more intuitive mobile experience that feels less like using technology and more like collaborating with an intelligent assistant.
