williangrios

I’m Willian Rios, a Web3 Full-Stack Developer with strong expertise in system architecture, blockchain, and microservices. I work across both backend (Node.js, TypeScript, MongoDB, PostgreSQL) and frontend (React, Next.js, Tailwind) technologies, applying Clean Architecture, DDD, TDD, and SOLID principles to build scalable and secure solutions.

I’ve architected and developed projects such as PrivateShow, an interactive live-streaming platform with monetization; Criptomilhas, a decentralized marketplace for airline tickets with stablecoin payments; and Mentorzinho, an AI-powered educational app for children.

Holding an MBA in Blockchain and Crypto Assets, I earned 2nd place at the NearX (Optimism) Hackathon 2024 and maintain an active portfolio of open-source projects on GitHub.

Driven by innovation, Web3, and automation, I’m passionate about building technologies that connect people, decentralize systems, and redefine the future of the digital world.
