Who we are

The Company

Innovation and agility grounded in reality.

As a Woman Owned Small Business (WOSB), PJR has advantages over larger competitors. Much like trying to turn an aircraft carrier, larger companies are not as agile as small businesses. Often, they are hampered by their size, making changes difficult and slow. Small businesses like PJR are lean and can be more innovative, trying new things because they aren’t slowed by extended, layered approval processes. PJR can also adapt products, based on customer feedback, much more easily than larger competitors. Speed and flexibility are advantageous when delivering new capabilities, and PJR can accommodate this better than its larger counterparts.

Extraordinary Experiences

Providing software for use by warfighters on ships.

Shipboard software must be able to operate with limited bandwidth, performance issues cannot be solved by simply adding compute and storage, and sailors are often using the software while under duress. Speedy recovery from failures is critical: losing access to communications and decision support systems for prolonged periods can put the ship and its crew in harm’s way. Cyber security requirements must be factored in throughout the software development lifecycle; fixing security vulnerabilities late in the development process is time consuming, and expensive, assuming late-stage software fixes are even possible.

Our Core Values

PJR’s Core values are our fundamental beliefs. These are our guiding principles that dictate our behavior and the difference between right and wrong. 

  • A commitment to innovation and excellence. Think different and don't compromise on quality.
  • A commitment to building strong communities. When able, PJR will donate to the University of Texas to improve student education and match employee charitable donations.
  • A commitment to doing good. PJR believes in making great products and building a great company without being evil.

PJR Team

Peter Allen Robinson
Founder and President

Peter, a serial entrepreneur with over 20 years experience running small businesses, started PJR Corporation with the vision of creating and growing a company that provides innovative solutions to real-world cyber security and legacy software performance problems. Peter is the principle investigator for PJR’s multiple Small Business Innovative Research (SBIR), Small Technology Transfer Innovation Research (STTR) and Rapid Innovation Fund (RIF) projects. Prior to PJR, Peter co-founded Mobile Access Software, Incorporated (MASI), a law enforcement records management and crime analysis software company. Peter grew MASI by hiring the right talent, offering great products, as well as developing strong customer and partner relationships. Peter developed an exit strategy with potential merger candidates. Ultimately MASI merged with Northrup Grumman Corporation. Peter has a Bachelors of Science in Electronics from Chapman University, and a Masters of Arts in Theology from Concordia University.

Sandra Leigh Robinson
Chairman of the Board

Sandra has over 25 years experience with small business contracts and finance. Sandra ensures compliance with the Defense Contract Audit Agency (DCAA), Defense Contract Management Agency (DCMA), Defense Security Service (DSS) Facility Clearance Branch (FCB) for PJR’s Facility Clearances and National Industrial Security Program (NISP).  Sandra handles all PJR contracts with customers, partners, and financial institutions. Sandra is also the lead for PJR’s banking, finance, advisor, and investment relationships for PJR. 

Scott Harris
Lead Software Developer

In addition to creativity and and sense of humor, Scott brings discipline and structure to PJR’s software development life cycle. Scott’s +10 years experience with Qualcomm, as well as successfully transitioning new software products into Department of Defense (DoD) programs of record provide a solid foundation for PJR’s products.  Scott respects the value of good documentation from beginning to end. Scott also understands the nuances of compliance with the DoD’s Risk Management Framework (RMF). Scott has a full range of experiences ranging from successfully developing/supporting software with hundreds of thousands of users to transitioning complete software systems to be supported by a competitive development team. Scott received his Bachelor of Computer and Information Sciences from University of Delaware.

Chris Shiflet
Software Developer/ Scientist

Chris has extensive experience with binary and dynamic static analysis of software. Chris’ work with call graphing, data flow, and control flow analysis influenced the engine at the core of PJR’s ArtusJava. Chris’ experience with tactical software enabled network engineering, especially ad-hoc networks for mobile and airborne swarms of autonomous vehicles has also proven invaluable. Chris has the big picture view, patience, and critical thinking skills necessary to transition basic research from the academic world to real-world applications. Chris has that unique ability to close the gap between the basic researchers’ ‘good enough to establish the realm of the possible’ and PJR’s need to produce a sustainable product for its customers. Chris’ education includes: University of California, Santa Barbara, M.S. Computer Science, Arizona State University, B.S. Computer Science and William and Mary School of Law, J.D., 20

David Diepenbrock
Software Developer/Scientist

David’s deep understanding of, and experience with, C/C++, Ada and Java inform our Artus Suite product development. David also worked on PJR’s STTR for Artus Protocol, a project to remove unwanted features from communications protocols. David’s vision is to remove protocol features that could be used by attackers, but aren’t being used in production. For example, removing the TXT or MX features from DNS if they aren’t being used in a customer’s final configuration of DNS. David’s philosophy is why leave a vulnerability in place if it isn’t needed.  David’s experiences also include C/C++ source code instrumentation, analysis and manipulation using libclang, as well as code optimization for the Longbow Apache Helicopter reducing boot time by 25%. David received a M.S. Information Management from Arizona State University, and his B.S. in Computer Science from Arizona State University.
