• Cloud Video Storage Solution
• Proactively and solely researched, architected, designed, and implemented a proof-of-concept for a cost-effective, scalable cloud-based video extraction, storage, and playback service.
• Made significant progress toward the corporate strategy of Software as a Service (SaaS) and recurring revenue models while helping to position the company for potentially massive revenue from cloud based storage.
• Developed a deep understanding of estimating cloud costs, including compute power, data storage, and data transfer.
• Architected a solution to allow integration of new cloud services into existing product architecture without requiring system-wide changes.
• Co-hosted a Productization Workshop for product managers to discuss monetization strategies.

• Accounts Service
• Identified the need for a utility to allow administrators to enroll customers to cloud services
• Architected, designed and proposed a solution to stakeholders
• Implemented a cost effective web based solution that allows cloud services to authenticate API calls while remaining stateless and without overburdening a database with read requests.
• Rabbit MQ,.Net 7, PostGreSQLPOS Translation Service
• Pro-actively conducted an experiment to port a Windows based POS translation program to work in Linux allowing numerous translators to be reused in future cloud based deployments

• Cloud Recording
• Researched cloud based object storage for design of a cloud video storage feature in a video recording application
• Became proficient with the AWS S3 C++ SDK and investigated aspects such as cost, alternatives and API compatibility
• Visual Studio C++, GitTranslation Service
• Reverse engineered legacy transaction data system
• Gathered requirements and created detailed system and software designs

• Primary responsibilities included designing, implementing new features and providing bug fixes for a Windows based tactical battle management system (TBMS) within the last eight months of a ten year contract.
• Implementation included use of C#.NET with WPF and XAML. All code modifications must adhere to pure MVVM architecture with no use of code-behind.
• Unit tests were written using the Moq library. Design and analysis documents were authored for each feature and also several sections of the end user documentation.
• Wrote several ad-hoc utilities to reproduce very rare difficult bugs.IAC Interface:
• Implemented an interface for external control of TBMS through an IAC (Inter Application Communication) Windows service.
• This interface was designed for IFCSS (indirect fire control software suite) and used XML based messages. It enabled two new remote functions; center map on target and zoom map to target, which are crucial components.

• Project: Pub Sub ToolsThe purpose of Pub Sub Tools is to provide the QA team with a way to simulate operation of the company's main product, a message router. It provides users with a command line interface and XMLRPC.
• Implemented new features and fixed bugs as reported by the QA team
• Integrated open source libraries (Proton-CPP, QPid JMS) to enable the QA team to test the message router's new AMQP 1.0 support. Installed Active-MQ 5.8 and J-Boss AMQ for use as a test environment and also.
• Acquired in-depth knowledge of the MQTT protocol, acquired functional knowledge of the web socket protocol and designed and implemented a set of C++ classes to add MQTT and web socket support to Pub Sub Tools.
• Reverse engineered the undocumented XMLRPC interface and created a collection of HTTP requests using Postman. This allowed convenient and simple control of Pub Sub Tools which aided in troubleshooting the test scripts.
• Ported the C#.NET version of Pub Sub Tools to.NET Core 2. Wrote code to seamlessly replace two open source libraries that were not compatible with.NET Core 2; NLog and XMLRPC. The XMLRPC library replacement was.

• Project: Online Patient Surveys
• The purpose of this project is to provide patients with a convenient means of providing feedback via surveys
• Handled all technical aspects of the project as technical lead
• Aided in technical requirements analysis and helped research data privacy requirements
• Co-architected overall system
• Researched online survey service providers and created a feature matrix, cost comparison and glossary of survey terms

• Project: Central Control System (CCS)
• The project goal was to replace the text based front end interface of a legacy system with a custom made web based application and eliminate the need to annually renew expensive support licenses.
• Participated in reverse engineering, design and implementation.
• Made modifications to stored procedures, helped direct team effort by regimenting software components to a common design pattern and gave troubleshooting help to team members.
• Technologies: ASP.NET, C# & IIS, HTML, JavaScript, CSS, SQL, XML, Web Services and Tortoise SVNProject: Familiar Faces
• Designed and implemented a solution to allow users to programmatically send faxes by calling a simple web method. This solution was implemented as a series of Windows services (C#.NET), web services (C#.NET & IIS) and.

• Project: CMA (Clinical Mobile App)
• Contributed to the development of a mobile application used by hospital clinicians by implementing new features using Apple technology.
• Technologies: XCode, Mac OS X, iOS, Objective C, HTML5 and SVN Project: CMA-DRP (Data Readiness Plan)
• Added features to a native iOS mobile application (CMA), by integrating a web based user interface and using a native app/web app hybrid approach.
• Designed user interfaces in JSP, HTML, JavaScript and Dojo.
• Developed server side software to run on IBM WebSphere and Tomcat using Java.

• Analyzed requirements and wrote a high level design of a sonar audio system feature as part of the maritime helicopter modernization project.
• Performed root cause analysis on reported software problems.
• Technologies: C++, UML, Rhapsody, VxWorks, Solaris, Linux, X-Windows, Clear Case/Quest

• Sherpa
• Designed and implemented software for an automated parachute guidance system.
• Prototyped (in Matlab), designed and implemented (C++) software for wind velocity estimation based on chi-squared data fitting algorithms.
• Technologies: QNX C/C++, Matlab, PC104, DOS, Falcon View, Google Earth, XMLSMP
• Performed root cause analysis on software and released repaired software builds
• Wrote a software utility for post mission flight path visualization.

• CBRN
