Becton Dickinson Diagnostic Systems (BD), Sparks MD

Software Architect, Team Lead, Product Owner & Scrum Master

I architected the software for a medical diagnostic instrument that performed real-time Polymerase chain reaction. The instrument is highly automated with sixteen robots and 116 embedded Ethernet devices. The system performs multiple different assays to identify viruses and bacteria based on DNA sequences. The instrument performs pre-analytic work, DNA extractions and DNA amplification and detection. The instrument is designed for high sample throughput and high availability.

The project consisted of over twenty software engineers. I was overall software architect and I also led one of the scrum teams. My team performed the collection of optical readings, processed the time series into metrics and finally the metrics into diagnostic results. We developed using two week iterations tracked with DevOps (VSTS) to facilitate the scrum process.

The system contains 86 controlled motion axis and hundreds of input and output devices. The architecture uses a Windows server and many embedded control boards. The user interface was Angular, OData, REST and ASP.NET MVC. The instrument control is a highly multi-threaded .NET Windows service that executes JavaScript assay protocol using the V8 engine in-process. The data layer was built on Entity Framework and SQL server 2016. Metrics on instrument performance were collected using Azure IoT Hub.

Constellation Energy Group (Constellation New Energy), Baltimore MD

Architect, Team Lead & Scrum Master

I led a team of full-time & consultant developers that created a customer account portal. The site is aimed at their 17,000 commercial and industrial retail electric customers. We provided power to these customers at more than a million service locations. Its presentation layer is ASP.NET MVC3, C# and .NET 4.0 framework. The middle tier is a collection of WCF services, some with HTTP bindings and others with TCP NET bindings. The backend data layer access customer data from Siebel, usage & billing from LodeStar, and account positions from a data warehouse. My staff built the front end and middle tier.

The site allowed customers to view and pay invoices, chart electrical usage, chart gas and electric commodity markets, review customer information, maintain their profile, and self-administer other users. The site also allowed small and medium businesses to renew their contracts. The site cleared more than 6 million dollars in payments the first year. The site provided a light user interface for small customers and a professional user experience for large customers.

Educational Testing Service, Prometric (formerly Thomson Prometric & Sylvan Prometric), Baltimore MD

Architect & Team Lead

I led a team of full-time & consultant developers to create a computer based testing driver. The application is being deployed to over 3,500 testing centers throughout the world on more than 40,000 workstations. The software has delivered more than 2,000,000 exams to date. It is a combination of VC++ 6.0 and Visual Basic 6.0 COM components. I designed the architecture using Rational Rose (UML), and I proposed the axioms of the design and convinced management to back the radical approach. I led the development of a new computer based test definition language using XML, HTML, scripting and XDR schemas. My staff built the exam compiler, test driver core, active-documents, and plugins. I met with many Prometric clients requesting use of this test driver. They included Microsoft, Cisco and Education Testing Service (ETS).

Also, I architected a scheduling and registration system for booking exam appointments internationally. The application is being deployed to 13 registration centers throughout the world on more than 250 workstations using a central data repository. It is a set of Visual Basic 6.0 COM and COM+ components that use a MS-SQL data repository. It also provides a web-service using XML to book appointments from client web-servers (b-to-b). I designed the architecture using Rational Rose (UML). I led the development of the software until a full-time technical lead could be obtained and trained.

Further, I led a team of full-time & consultant developers creating a testing center administration system. The application is being deployed to over 500 testing centers throughout the world on more than 10,000 workstations. It is mostly Visual Basic 6.0 COM components that use a MS-SQL data repository. It uses DCOM communications and supplied remote monitoring using IIS & ASP. I designed the architecture using Rational Rose (UML).
