Senior🎓
Top SchoolMike Harwerth is a seasoned software engineer with nearly a decade of recent experience and a long history designing and scaling distributed systems, desktop applications, and test automation platforms. He has led technical teams at UnitedHealth Group and Wells Fargo, building Selenium/Cucumber acceptance frameworks, service virtualization, and service-bus integrations while managing critical non-production environments. Deeply versed in Java, C/C++, Swing/SWT, and CI-driven development, he excels at full lifecycle delivery from protocol/compiler design to automated testing and deployment. At Nortel he designed protocol definition and codec frameworks, led offshore compiler work, and even earned a patent for a signal-quality testing approach—evidence of practical inventiveness. His open-source work includes back-end contributions to an ESP32-focused Modbus library, highlighting a continued hands-on interest in embedded and protocol-level engineering. Based in Minnesota, he blends pragmatic leadership with low-level technical depth, often removing dependencies to accelerate parallel development.
