Senior🎓
Top SchoolCassio Seffrin is a software engineer with nine years of professional experience building distributed microservice backends with Spring Cloud and full-stack applications using Node.js/React and mobile apps in Flutter and React Native. He combines hands-on engineering (C/C++, Java, Perl, PHP) with practical operations skills—server and email administration, virtualization, and network monitoring—from long-term roles in IT and DevOps. As a university professor he teaches Object Orientation, Process Modeling and Software Development, which keeps his engineering practice grounded in pedagogy and current best practices. Based in Santa Catarina, Brazil, he has a master’s in Computer Software Engineering and a track record of delivering REST APIs, hybrid frontends and cross-platform mobile solutions across enterprise and academic environments. An understated strength is his ability to move between low-level middleware and user-facing UX, making him effective at end-to-end system design and mentoring junior engineers.
