## About Me

I am a full-stack architect with 8+ years of experience building scalable, high-performance web applications across web3, cloud, and full-stack product environments. I specialize in TypeScript, JavaScript, Rust, Solidity, and modern frontend/backend ecosystems, and I focus on shipping clean, maintainable systems that hold up under real-world use.

I lead engineering teams, establish architecture standards, and translate complex product requirements into practical technical solutions. I work best in fast-moving startup settings where ownership, velocity, and strong architecture all matter equally.

My recent work has centered on AI governance infrastructure, open-source donation systems on Stellar, decentralized security infrastructure on EOS EVM, and AI-powered RAG systems. I have built products involving passkeys, escrow workflows, smart contracts, blockchain indexing, real-time streaming, and multi-chain data systems.

I also have deep experience in frontend engineering, including React, Next.js, React Native, Gatsby, and UI/UX implementation. I have delivered work for webinar platforms, e-commerce systems, corporate sites, research platforms, and mobile navigation apps, often integrating APIs, CMS platforms, and performance-focused build pipelines.

On the backend and infrastructure side, I have worked with Node.js, Elysia, GraphQL, REST APIs, PostgreSQL, Redis, Docker, Kubernetes, AWS, GCP, and CI/CD systems. I value testing, documentation, security, and modular design, and I often apply context engineering and agentic workflows to improve development quality and maintainability.

I am based in Costa Rica and work remotely with global teams. I am open to contract and freelance opportunities worldwide, and I bring a strong blend of engineering depth, product thinking, and creative problem-solving to every project.
