Project Sample

CMS Arts:  CMS Arts is a web based financial management application written to handle billing for the Department of Health and Human Services.  This system had an advanced reporting requirement and real time access to data for attaching and communicating with government officials.  System was built to handle thousands of simultaneous users.

 

FDA MAED:  Began project with a limited architecture where the system was only able to handle 3 simultaneous users.  I worked with the FDA to rework the architecture and build the proposal for a massive overhaul which resulted in the ability for the system to handle 100s of users.  MAED is a Java application with a SAS analytics engine back end.  I regularly worked to troubleshoot the legacy SAS macros to fix problems and help users with issues.  At the same time we greatly extended the capabilities to enhance the visualization of standard and non-standard data.

 

NCARB Architectural Qualifications Manager:  This application managed the 100,000 current architectural licenses in the country and the certification process which students must undergo to become a certified and licensed architect.  This system was also required to store historical records of students and architects since the time when licensing became a requirement in 1857.  This tremendous volume of data was designed for the Azure cloud and integrated into the Azure cloud framework with Microsoft SharePoint as the original front-end.   However, the company did move away from this solution and instead used a different web based platform.

 

Alumni Fidelity:  written as a contract with R2Integrated employed by that organization.  This system handled the collection and submission of fund raisers for the purposes of collecting money.  Alumni Fidelity facilitated highly complex algorithms for alerting users, collection donations, and managing fund raisers. This system also had social networking capabilities that would allow users to communicate inside the system.  Also, reports were created which clearly showed how these funds stood compared with the target and goal amounts.
