Phillip Roesch

I’m Phillip Roesch, a systems-focused professional with a strong background in healthcare billing operations and security. At KidsPeace Corporation, I currently serve as the primary administrator for Optum's Assurance Reimbursement Management software, where I oversee system configuration, automation, claim processing, and data integrity between EHR and clearinghouse platforms. I drive reporting at multiple cadences and manage support operations to ensure timely payment resolution. Prior to this, I worked as a Security Engineer at CertiK, where I audited decentralized financial applications, reviewed smart contract code for vulnerabilities and efficiency, and led business onboarding to align project teams with security best practices. My dual experience in healthcare technology and smart contract auditing reflects a unique ability to manage complex systems, ensure data accuracy, and secure digital infrastructure. I hold a B.S. in Computer Science with minors in Applied Mathematics and Data Science from Wentworth Institute of Technology.
