Rockstar🎓
Top SchoolJoão Reis is a software engineer with 13 years of experience blending robotics middleware expertise and systems-level C++ development with practical DevOps and build engineering for large open-source projects. Trained at Instituto Superior Técnico (BSc/MSc), he led middleware transitions in long-running robotics projects (SocRob) and later contributed significantly to Node.js infrastructure—improving Windows build tooling, node-gyp, and libuv filesystem/timer/tty implementations. He currently collaborates on Node.js core at Janea Systems while also having founded an early-stage energy startup where he built backend prediction and data infrastructure. Comfortable across embedded MSP430 work, ROS integrations, Java APIs, and cross-platform build automation, he brings a rare combination of robotics real-time constraints and large-scale open-source build/test automation. Notably, his contributions helped modernize Windows support in critical tooling used by countless Node.js developers.
