I’ve done various projects for a number of clients through my own
consulting company, and listed below are some of the more interesting projects
I have worked on.
WPF & XAML
with MVVM –
Engineered a C# video clip list player application that plays videos. The
player has Play, Pause, Stop, Browse and Full Screen buttons as well as sliders
for Volume and Seek To. There are also controls for messages, current URL,
current position and video length.
Videos can be local or streamed across the internet. The screen size,
location and state are persisted in the registry along with the current video
source, position and volume. Additional controls exist to Add, Open, Save or
Play a playlist. The playlist properties are source, volume, start and stop
positions which are persisted. The playlist is saved in an XML format. The
keyboard can be used to Quit, Play, Pause, and Show or Hide the controls or
Toggle Full screen mode. This application does not edit video; however it will
play back video segments in your preferred sequence and volume. This
Application and / or source code is available for licensing.
Engineered C# Automated Commodities Trading program HT-TWSAPP.
This C# multithreaded TWS App retrieves and processes live market data to make
real time trades and compute P & L which provides feedback to the
configured trade strategy. Trades are made via the Interactive Brokers Trader
Workstation API using the socket interface.
Tick by tick data is saved to a MS SQL Server for back test runs to test
new strategies. This Application and / or source code is available for
licensing.
Engineered C# Tic-tac-toe
game, play local or an opponent across the internet or against an almost
terminator like learning computer aka the AI
(Artificial Intelligence). The AI can learn from experience and apply that knowledge
to goal directed action, in this case to win or to avoid losing. The AI uses concepts of positive
reinforcement, negative reinforcement, detect bad move, and rotational
symmetry. The program uses ClickOnce deployment. Used TCP related classes NetworkStream,
TcpListener, Socket, and TcpClient
Project
completed. This Application and / or source code is available for licensing.

over a piece that you can legally move to. Drag the piece to move it. When you
left click and hold to make a move the piece moves up and follows your
mouse. Move the mouse to one of the
pinkish legal destinations. When the mouse is over the legal destination of
your choice the board color turns dark green. Release the mouse button to complete
the move. The program uses ClickOnce deployment. Client: Janet Coelho
