CTO & Founder

As the founder of DTI one of the many responsibilities require traveling on a week to week basis to client sites and assisting clients with their current Network Security (PKI, Kerberos, SSL, Firewall tools, Certificates, Blowfish, RC4, RC5, DES, 3DES, etc.). LDAP/Active Directory and Software issues. Developing a proposed architecture according to their current status and listing how to secure their current applications utilizing numerous portal software tools such as Netegrity's SiteMinder. Developing and customizing Netegrity’s API for different client’s environments these were mainly done in (COM, DCOM, C++, and some in JAVA).
Many other responsibilities include developing new ideas, budgets, and business proposals. As well as software and web development, engineering and reengineering of current applications (C/C++, JAVA, CORBA, JSP & Swing technology). All of this is done practicing best business practices, and done in a timely fashion. Developed marketable encryption software named Valor, which stands for bravery in Spanish.

06/97-04/99 New England Medical Center, Boston, MA

Informatics Core Director

In charge of developing new technologies for National Institute of Health funded General Clinical Research Center (GCRC).
Developed over 20 Extranets and Intranets utilizing SUN Ultra Sparc 10’s systems. Developing Blowfish, RC4, RC5, DES and 3DES encryption on all CSU software & data base applications. Meet with product vendors and sales engineers of various companies with new possible tools and demo's for Clinical Studies Unit.

90% of Database applications were developed utilizing Oracle 8 as a backend. All web applications were developed in C/C++, JAVA, JSP, CGI, ASP, HTML, DHTML, XML, etc. Met and trained Clinical Investigators and staff on their new applications.

All new technologies applied on all GCRC applications must have been HIPPA security standardized for subject (patient) confidentiality.

04/92-07/97 US Army

Counter Intelligence Special Agent (97)

Work Center Supervisor (75F)

As a Counter Intelligence Special Agent (97B) duties included PSYOP (Philological Warfare Operations) and interrogations.
As a Systems Engineer/Work Center Supervisor (75F) duties included assisting in the development, supervising and revising specs for a team of 20 SIDPERS developers. SIDPERS-3 provides and maintains the Personnel Management Information System for the active duty Army.

SPIDPERS-3 was developed in C++ and tested in several UNIX environments. This was necessary for Y2K compliance and transition of a paper to paperless environment by developing bar coded ID cards that will hold all soldier records. Worked in numerous projects with DoD security agencies in order to learn their encryption and algorithms structures; this was for future development of numerous encryption software utilizing state of the art encryption algorithms.
