About

Software Development Engineer & Web3 Builder currently studying Software Engineering at Universidad Fidélitas, with strong experience across the full stack and a deep focus on blockchain and decentralized systems.I specialize in modern web development and backend systems using Next.js, React, TypeScript, JavaScript, Node.js, Express, and NestJS, building scalable, maintainable, and user-centric applications. I have a passion for UI/UX design, focusing on clean interfaces, intuitive user flows, and design systems that improve usability and product adoption. On the blockchain side, I develop smart contracts on Stellar (Soroban) using Rust, and have hands-on experience with Cairo and Starknet-based ecosystems.I was an active open source contributor through OnlyDust, where I collaborated on multiple Web3 projects, contributing production ready code, improving the developer experience, and participating in the growth of the decentralized infrastructure.Beyond engineering, I am a founder and product-driven builder. I founded Numo, a Bitcoin-focused DeFi platform, and I am currently founding Neko Protocol, a Real-World Asset (RWA) DeFi layer on Stellar, as well as Oppia Labs, an innovation studio focused on building open-source, decentralized solutions with real-world impact. Through these initiatives, I work across product strategy, system architecture, smart contracts, and frontend integrations.I have a strong interest in Artificial Intelligence, particularly in how AI can enhance developer tooling, automation, and user experience. I am highly proactive, adaptable, and goal-oriented, with a strong ability to learn quickly, solve complex problems, and collaborate effectively with developers, designers, and stakeholders to deliver impactful solutions.
