About Logan Mulderrig

I build test automation programs that scale—from zero to test cases—while solving problems others call impossible.At Pentair\'s IoT division, I led the mobile test automation program for pool equipment, personally writing 500+ test cases. When iOS/Katalon compatibility barriers blocked automation, I developed a coordinate-based framework that enabled 300+ test cases everyone said couldn\'t be automated. I integrated RS-485 hardware communication into our test suites, creating true end-to-end IoT testing across pumps, chlorinators, and lighting systems.The results: 80% coverage of automatable tests, 50% reduction in regression time, 200+ defects caught across 50+ release cycles, and 4x more release candidates tested per sprint.Before Pentair, I went from QA Engineer to Manager of 40 people in under 2 years at Prometheus Group—with zero prior QA experience. I owned hiring, firing, and performance management while modernizing QA practices and introducing Cypress automation across 15+ product teams.I chose to return to hands-on automation architecture because I love building systems that scale. I\'m equally effective as a senior IC going deep on technical problems or leading teams to build quality organizations.
