Inventor, Engineer, and Credit Union Volunteer
Karl Appel
My experience with credit unions is defined by a unique combination of hands-on technical execution, supervisory experience oversight, and high-level strategic governance. With seven years of experience on the Supervisory Committee of Sunmark Credit Union and as a current board member, I view technology not just as an IT function, but as a critical pillar of risk management and fiduciary responsibility. I designed this solution to strictly separate sensitive communications from internal management and IT staff, ensuring confidentiality and maintaining proper checks and balances within the organization.
On the technical front, my software development and consulting work focuses on helping credit unions understand advanced capabilities, including high-risk banking. Additionally, I have bridged the gap between technology and regulation by helping implement the technical compliance frameworks for my current credit union, ensuring that our systems handle the necessary NCUA regulations and security requirements demanded by law.
