Samuel Romario Hernandez Benitez

I build high-performance Web2 applications and secure Web3 on-chain architecture. If you need a developer who understands both complex backend logic and pixel-perfect frontends, I can help you ship your product to production fast.
What I bring to your project:
Web3 & Solana: Custom smart contracts using Rust and Anchor, decentralized escrow protocols, and seamless frontend integrations using Next.js and Web3.js/Anchor providers.
Backend & Infrastructure: Scalable REST/GraphQL APIs with Node.js/TypeScript, serverless deployment with Cloudflare Workers, and optimized PostgreSQL/Supabase databases.
Frontend Performance: Highly responsive UI/UX built with Next.js, React Native, and Tailwind CSS.
Proven Experience:
Developed decentralized escrow and matchmaking platforms for competitive eSports integrated with Solana.
Built production-ready ticketing management systems and robust point-of-sale (POS) software with real-time sync.
Certified Scrum Fundamentals (SFC) professional. I don't just write code; I follow agile workflows to deliver clean, documented, and tested features on time.
