Ongoing Projects

Login Control GUI using Python and SQL

I developed this application using both Python programming and SQL together. I applied the Model-View-Controller (MVC) software design pattern concepts for the benefit of separation of concern. This was done by applying object-oriented programming with each MVC element separated into its own class file. I used Python's TKinter library for the GUI and SQLite module for the database.

Computational Electromagnetic Simulations

I used finite difference time domain techniques to model the interaction of electromagnetic fields with physical objects and the MRI environment. The simulation models were developed programatically with Python API's to be automated and the simulated results were used to develop verification & validation (V&V) protocols, which are critical components of a quality management system such as ISO/IEC 17025.

Temperature System Logger with Python using RS-232 Communication

I developed this application to interface laboratory hardware (i.e. a Temperature System Conditioner) using Python programming. I used an MVC software design pattern with OOP to separate each MVC element into its own class file. I used Python's TKinter library for the visuals and created my own methods with the PySerial module for the serial RS-232 communication.
