Rockstar🎓
Top SchoolRon Leisti is a software architect with 15+ years of experience designing and delivering high-quality, secure systems across medical imaging, banking, and supply-chain domains. He blends deep hands-on expertise in server and web architectures, databases, threat modeling and performance-critical C/Java systems with a pragmatic focus on clean code, automated testing and CI. At Agfa and Radical Imaging he led zero-footprint medical viewer work requiring strict regulatory and security controls, and at NetSuite he drove architectural improvements for cloud-based inventory and analytics features. Comfortable across stacks—from C++ and Java to JavaScript, Clojure and cloud microservices—he gravitates toward challenging problems like scalable imaging pipelines and data science integration. Known for introducing tooling and process improvements (custom testing/profiling and scripting for onboarding), he pairs technical depth with a history of cross-team collaboration in global organizations.
