Tools & Skills
Becton Dickinson Diagnostic Systems (BD), Sparks MD
Software Architect, Team Lead & 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 VSTS to facilitate the scrum process.
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.
