Sr. Software Engineer/Tech Lead/Product Owner/Technical Consultant 10 Feb to 16 Oct BD Bio Sciences, San Jose, CA

BD Biosciences is a division of Becton, Dickinson and Company, which is an American medical corporation. The division sells tools for cell analysis and other laboratory products. I started off at BD as a contributor for PLA (Product Line Architecture). Gradually moved on to FACSuite™ which is a Clinical Diagnostic Flow Cytometry Software. Primary Responsibilities as a Technical Consultant/Senior Software Engineer

• Collaboratively design the FACSuite application using PRISM/Unity architecture utilizing its core components including BootStrapper, ModuleInitializer and, RegionManager as a Modular application implementing the MVVM pattern.

o Utilized Modular Core Concepts to separately Registering/discovering, Loading and Initializing modules either for RUO (Research Use Only) or Clinical application o Applied View-Based Navigation employing RegionManager to implement the 5 main modules of the FACSuite application, namely, User Management, Setup & QC, Experiment, Worklist and Library.

• The FACSuite Modules were developed using MVVM concepts achieving navigation interaction with views and with view models by registering the views with RegionManager and activating regions (via the DataContext property).

• Utilizing WPF, designed and implemented various UI elements (either wholly or partially) such as: o Cytometer Instrument Panel, Tube Settings, Tube Properties Dialog o Header/Footer Panel for the Reports

o Assay Properties Dialog, Audit Trail, E Signature Indicator o Keywords Model – organized as FCS, BD Defined, Custom Keywords;

• Utilizing Entity Framework, collaboratively implemented multiple options to store the various elements. o Worklists, Keywords, User Settings, and Reagents stored as Tables o Complex objects of Worklists such as Methods directly as BLOBs (Binary Large Objects)

• Applied async and await constructs to achieve async programming

• Collaboratively participated in the implementation of Experiment and Worklist Modules. o Applied several performance enhancements in Worklist Module related to

• Loading Worklist Entry

• Adding/Deleting Worklist Entries

o Applied several performance enhancements in Experiment Module related to

• SOV (Spill Over Values) updates during Previewing

• Involved as a key contributor to Gates in DataSpaces where the gates in the Plots responded to changes to RValues thereby maintaining a consistent Event Count for the affected gates Primary Responsibilities & Objectives as Product Owner/Tech Lead

• As a Product Owner, define user stories for FACSuite in consultation with stake holders. Put them in the Product Backlog. Participate in regular PO meetings assisting other POs in accurately defining the Acceptance Criteria.

• As a Tech lead, discuss various approaches with the onsite/offsite representatives.
