Top SchoolZac Hallett is a seasoned software leader and founder with 14 years of experience helping healthcare and public-sector companies design secure identity and compliance-focused architectures.

His background includes directing engineering at ID.me where he led efforts to achieve Kantara certification at NIST 800-63-3 (IAL2/IAL3), and scaling teams and infrastructure across roles from lead engineer to director.

Based in Manassas, VA, he pairs deep cloud and identity expertise with a knack for mentoring teams to ship clean, maintainable systems.
