Rockstar🎓
Top SchoolHayley Call is a technologist with 11 years of experience who transitioned from a Security Software Engineer at Microsoft to pursuing a Doctor of Chiropractic while tutoring PASS lectures at Palmer College. At Microsoft she worked on backend systems including notable contributions to the open-source onefuzz fuzzing-as-a-service project, where she refactored async runtime usage and implemented coverage-to-Cobertura XML conversion. Her background blends computer science and government studies from UT Austin with international study in war studies and interdisciplinary coursework in Edinburgh and King's College, reflecting both technical depth and policy-minded curiosity. She has hands-on experience across security engineering, cloud services, and developer tooling, plus internship experience in public policy and legislative offices. Comfortable moving between rigorous engineering problems and people-focused roles, she brings practical systems thinking to both software and clinical learning environments. An uncommon combination of production-grade security engineering and emerging clinical training gives her a unique perspective on risk, systems, and human-centered outcomes.
