Dan Kelosky is a Master Software Engineer with a decade of experience designing and delivering both new solutions and enhancements for legacy mainframe and distributed systems. He blends low-level system work in IBM assembler, Metal C and C/C++ with modern microservices and web stacks (Java, Node.js, TypeScript, Spring) and has prototyped editor tooling and CLIs. At Broadcom and CA he led technical teams, mentored hires, ran interviews, and drove customer-facing roadmaps—often bridging z/OS mainframe internals with cloud-friendly microservices like Zowe. Comfortable diagnosing production issues from dumps and traces, he also creates CI/CD pipelines and presents at industry events and training programs. Outside engineering, he serves on a local school board, reflecting a commitment to community impact beyond code.
