• Merrill's Roxy Cinema
  Website Final project for database class (CS 148) focusing on the back end managing adding movies & updating showtimes for a generic movie theater
• Invert Checkbox Selection (& deselect radio buttons)

  Website Final Project for web design & css class (CS 142)
• Pure CSS Dropdown
  Adapted existing tutorial to create mobile-friendly responsive menu. (Most work is not mine, but I added comments to help myself & simplify some CSS)
• Intro Web Design Final Project
  Very simple site for a fake graphic design company. Not my proudest work now, but it was a start when I was learning

Team Projects (Repositories Contributed to)

• Books 4 Equality repository and Live Site
  Website for a Student-run club that lends out free textbooks to UVM students
  Site runs in Node.js but I mostly worked on the front-end

Java

• GPA Calculator
  A GPA calculator in JavaFX attempting to use the Model View Controller (MVC) pattern
• Even or Odd Game
  Replicated a simple Android app using JavaFX & skills I learned from CS 110 at UVM
• Tetris Game
  Final Project for CS 110 at UVM
• Minesweeper Algorithm
  Simple iterative solution to counts mines in Minesweeper
• Mastermind Board Game
  Command line implementation of the board game Mastermind for a Software Engineering class
• Set Game Valid Set Finder
  Algorithm to find valid sets in the Game Set & potentiall provide hints. Iteratively implements n choose k for combinations & checks if any are a valid set.
• Fibonacci Algorithms Runtime Comparison
  Array Memoization, Recursive & Phi (Golden Ratio) formula
• Prime Factorization (Java)
  Cobbled together various existing algorithms for finding Prime Factors. I did not design the algorithms, but focused on creating a way for users to interact more easily
• Pascal's Triangle
  Used my knowledge of Java arrays to print out an arbitrary number of rows of Pascal's Triangle
• Java Rounding Improved
  A function that allows you to specify how many decimals to round to
• Java Random() Improved
  Several overloaded methods to allow you to specify an upper and lower bound for random numbers
• Loop Performance (i++ vs ++i)
  Runtime comparison between post and pre increment
• Algorithm Implementations
  • Graph Algorithms
    • Breadth First Search / Depth First Search
      Implementation of the common BFS & DFS algorithms
    • Bipartite Graph Testing Algorithm
      Modification of Breadth First Search to identify bipartite graphs
    • Strong Connectivity
      Application of Breadth-First Search to see if a directed graph is Strongly Connected
    • Topological Ordering
      Finds a Topological Ordering of vertices in a Directed Acyclic Graph
  • Greedy
    • Interval Scheduling
      Greedy Algorithm to find the maximum number of mutually compatible jobs
    • Interval Partitioning
      Java Implementation of the greedy algorithm for the Interval Partitioning Problem
    • Minimizing Lateness
      Greedy Algorithm to minimize lateness when scheduling jobs on a processor
    • Kruskal's Algorithm
      Finds a Minimum Spanning Tree from a graph. Add lowest weight edges unless doing so causes a cycle.
    • Reverse Delete Algorithm
      Greedy Algorithm to find a minimum spanning tree in an undirected graph by deleting heaviest edges unless it would disconnect the graph
  • Divide and Conquer
    • Counting Inversions
      Finds how similar 2 lists of rating are using the Divide and Conquer approach. Extension of MergeSort that actually displays the specific inversions as well as just counting the total number.
  • Dynamic Programming
    • Weighted Interval Scheduling
      The classic Dynamic Programming problem implemented in Java
    • Knapsack Problem
      Implementation of the classic 0-1 Integer Knapsack Problem
    • Sequence Alignment

    • Bellman-Ford Algorithm
      Shortest Paths from every vertex to a goal vertex allowing negative-weight edges
  • Flow Networks
