Price Water House Coopers (2001 - 2002)

Role: Software Architect

Challenge: Provide software development expertise, system design and development effort.

PriceWaterHouse coopers was contracted by the State of Ohio Department of Education to develop a web based enterprise application to generate unique identification numbers for Ohio’s 1.2 Million K-12 students.

State computerized record systems need a unique identifier (or S.I.D. StateIDentifier) to track the statistical performance of Ohio’s students.

Existing unique identifiers may not be used (such as SSN’s) for privacy and security reasons. Therefore, a new identifier must be created. This new identifier must be made, without generating duplicates, and without confusing one student for another.

Since the state education system is broken up into districts, a careful approach in the design of the system was used to ensure Students receive an SID for the State, but NOT the personal data of the students.The system may ONLY show the State an SID number, and only authorized personnel in a district my view any personal information. This personal information is very limited, and is only used to help generate the SID number.

Role: Senior Software Engineer

Challenge: Rapidly develop software to interface with a BioMetric device (hand geometry scanner), co-developed inmate image display, and provided Microsoft Programming technology expertise for other team members.

Battelle Memorial Institute was contracted by the Ohio Department of Rehabilitation and Corrections to re-design and develop an application to scan and track information concerning prison inmates in the new “SuperMax” facility.

This new application features included scanning of inmate’s hand into a BioMetric device (for door access), capturing inmates image, initiating and tracking prisoner transfer routes throughout the prison. Furthermore, the system is an Enterprise wide application used by hundreds of prison personnel from dozens of client workstations.

The real challenge was to build the software to interface a biometric device which would integrate with the application and database, in order to store the image of each inmates hands.

With the system completed in time, and on budget, the “SuperMax” facility is now able to efficiently transfer prisoners between cells, and provide even greater control and security of the inmate population.
