Software Design Engineer

Responsibilities:

• I took ownership of the Winforms component of the Microsoft Windows .NET Compact Frameworks.
• Winforms originally implemented as a direct port of the Windows desktop code causing glaring performance problems that made Winforms unusable on devices.
• I proposed extensive rewrite of Compact Frameworks Winforms code creating very thin layer of managed code evident to the consumer of Winforms, with much to most of the internal Winforms code being moved to native code layer allowing for overall reduction of managed code footprint / reduction of invocation of the just in time compiler (JIT) / reduction of huge number of interoperability calls creating overall performance gains on devices which just didn’t have the horsepower to run the heavyweight managed layer.
• I contributed as member of a two-person team defining COM interface for DIP (Device Integration Package), a data transfer component for Visual Studio for Devices.
• DIP component accomplishes transfer of data for code replication to device as well as email, contacts, etc. using various transports including networking and USB.
