Entrepreneurial Career
In 1990, he co-founded a defense contracting company that grew into a trusted partner for both government and enterprise clients. Five years later, he established a digital signature company, creating solutions that reshaped authentication methods across federal systems.
As an officer in both companies for over sixteen years, he led projects that delivered large-scale financial systems and advanced cybersecurity frameworks.
Digital Signature Innovation
One of his most important contributions was developing the first Department of Defense–approved digital signature solution, which multiple U.S. agencies later adopted. His financial management system for the U.S. Army Corps of Engineers became the only one to pass the CFO Act audit for fifteen consecutive years without exception.
Key milestones included:
Early smart card technology adoption in the U.S.
Development of ESIG, the first digital signature prototype for USACE (1992)
GAO-recognized legally binding electronic signatures (1993)
Creation of DBsign®, a database signing solution using RSA encryption
These efforts helped shape national standards for electronic security, in collaboration with GAO, NIST, OMB, the State Department, and the Census Bureau.
Career Milestones
Professional highlights include:
Input to the DoD Public Key Infrastructure (PKI) Roadmap (2000)
First JITC certification of a digital signature solution (2001)
DoD-wide deployment of digital signature software (2003)
First NIAP Common Criteria Validation (2005), followed by a second in 2011
Mobile device digital signature advancements (2016)
Cloud-based signature solutions (2018)
Cybersecurity Maturity Model Certification (CMMC) Level 2 (2023)
His innovations continue to support millions of Department of Defense users and beyond.
