About Me

I am a second-year student at Lehigh University studying Computer Science and Engineering. I am passionate about software engineering and cybersecurity. I am proficient in Java, Python, Excel, and C++, with experience in Swift, TypeScript, JavaScript, HTML, and CSS. I enjoy learning through personal projects and continuously developing my skills. I am currently finishing an ISC2 Cybersecurity course and plan to acquire more certifications.

Projects

Class Projects

Sample Netflix System
- Developed a simple alterable Netflix System incorporating a sample system of selectable options practicing creating and altering arrays of content, storing and altering large amounts of information for different users, and utilized multiple classes and functions to simplify the main code.
Sample Media List
- Developed a proof of concept program using multiple abstract parent and child classes to define different types of Media. With these objects, I read and wrote the sample list to a file, ran different types of searches and sorts over them all, and implemented various catches to improve my programming and problem-solving skills.
Many, many more
- Hundreds of proof of concept and test programs to practice and master various topics, such as object-oriented programming, creating and manipulating arrays, reading and writing to files, utilizing recursion, and creating and manipulating variables to store all types of input and accomplish any problem.

This website was entirely developed by me and hosted on GitHub. I learned HTML and CSS from scratch using online resources and trial and error.

Experience

Artificial Intelligence Course
- Used the basics of Artificial Intelligence and machine learning to operate a car that could autonomously drive while using detecting road signs, pedestrians, and stop lights. This car was programmed and trained on data comprised of pictures of our "road" to isolate the lines and relevant objects to accurately navigate situations.
Applied Engineering Computer Methods Course and Lab
- Used Python to solve Engineering problems, utilizing file reading and writing, regression and plotting graphs.
- Labs consisted of using a Raspberry Pi to develop a robot to solve a variety of challenges, ending with implementing machine learning to autonomously drive and steer the robot away from obstacles.
Introduction to Engineering Practice Course and Lab
- Utilized TypeScript to develop a basic racing video game which included a dynamic shifting background, different difficulty levels and settings, and many different objects which served as obstacles in the game.
Introduction to Programming Course
- Problem-solving using the Java programming language. I used data types, control flow, methods, arrays, objects, and inheritance to solve a variety of issues.
Introduction to Programming and Data Structures Course
- Used Java to design and implement algorithms and data structures. Built off prior experience using conditional statements, loops, arrays, and object-oriented programming. Developed algorithmic techniques such as recursion, algorithm analysis, and sorting and implemented data structures such as lists, queues, stacks, trees, and hash tables.
Foundations of Discrete Structures and Algorithms Course
- Learned basic representations used in algorithms: propositional and predicate logic, set operations and functions, relations and their representations, matrices and their representations, graphs and their representations, trees and their representations. Also learned basic formalizations for proving algorithm correctness: logical consequences, induction, structural induction as well as basic formalizations for algorithm analysis: counting, pigeonhole principle, and permutations
