João Casarin is a full-stack software engineer based in São Paulo with ~8 years of hands-on experience and a degree in Computer Engineering. He builds and maintains scalable microservices and web applications using Java, Spring Boot, Node.js, React, and AWS, and has operational experience owning CI/CD pipelines and Jenkins/YAML-driven deployments to EKS. At Instituto de Pesquisas Eldorado he processed real-time factory data at scale, simplified mobile backend versioning, and automated developer workflows—work that improved operational decision-making and shaved hours off repetitive tasks. Comfortable across backend, frontend, and DevOps, João pairs readable, testable code with constructive code reviews and mentoring, and brings an early-career background in teaching that strengthens his communication and collaboration. Now at WEX, he continues to focus on reliable, production-ready services and developer productivity.
