Senior🎓
Top SchoolRui Hayashi is a seasoned software engineer with 14–15 years of experience blending Java architecture, technical leadership, and pragmatic DevOps practices. He has delivered production systems across logistics, CRM and help-desk domains for clients like Toyota, Nissan and Klabin, and has a track record of introducing CI/CD, code review practices and automation that improve team productivity. At Tecsinapse he led cloud infrastructure and built tools that auto-generated Jenkins jobs to give developers controlled access and a consistent deployment experience, and he later expanded his platform skills at Nubank. Certified Jenkins Engineer with deep practical experience in Chef and AWS, Rui also studies Clojure, ClojureScript, Go, Docker, Ansible and Google Cloud and can ramp quickly in those stacks. Colleagues praise him for reliably delivering on time and continually improving systems rather than leaving them as he found them. Based in Greater São Paulo, he combines hands-on implementation with an architect’s eye for robust, automatable infrastructure.
