    Shortest Path Grid Traversal Program (C Programming and Data Structures / Algorithms, 2021)
    Nov 2021
    The final project of Purdue University's Data Structures course challenged me to independently develop a program capable of computing the shortest path from the top of a weighted grid to the bottom of the grid. This project required me to understand graph theory, structures, and most of all runtime analysis. Ultimately, my code ran flawlessly when tested with a large set of test cases alongside hundred of other student programs. Needless to say, what I gleaned most from the Data Structures course was an ability to debug for efficiency and accuracy.

    WebGen - Python Based UI Compiler (User Interface, Website Design, and Python, 2021/2022)
    Aug 2021 - Mar 2022 (8 months)
    WebGen is a custom Python to User Interface compiler with the goal of making website and app design cleaner and more efficient. WebGen uses Python classes to represent HTML elements, creating repeated structures much more reliably than copy/paste. Javascript, CSS, and PHP global files can be created and linked to pages, giving creators the ability to use the same pieces of code on every site. WebGen was used to build this Portfolio and was updated in the process. WebGen operates much more smoothly than programming from scratch in HTML, while still presenting the customizable flexibility of creating a website through code.

    GPS-Based 3-Dimensional Coordinate Plotting Program (Python, MATLAB, and Data Processing, 2020)
    Jul 2020
    While working for Leak Location Services, Inc., a geomembrane liner inspection company, I developed a system for geographically mapping large project sites. Using the basic GPS of a mobile phone, I was able to obtain the 3-dimensional coordinates of a site. These coordinates were then taken and plotted 3-dimensionally to produce a map of the project site. This system proved especially useful for determining the project site dimensions, tracking the location of liner defects, and producing client deliverables.
