Taught by Ms. Taricco, Computer Science (CS) involves learning the computer programming and the problem-solving skills necessary to succeed in the field. As a student in the advanced section, I work on my independent CS project and create advanced algorithms to solve problems.
Cryphor is a 3D capture-the-flag game I am developing in Unity (C#) with two other students (Medhansh Choudhury & Anshu Adiga). Players on opposing teams try to reach the other side without getting their flag broken by other players. The game is still in development, but you can view a video of our progress here.

Earlier in the year, I worked on an algorithm called Chmod, a Java parser that takes an octal input and returns the permissions of the file. The algorithm is based on the Unix file permissions system and was simulated in Java. You can preview the code for the project here and download it here.
Apps For Good (AFG) is a program that allows students to create their own mobile apps to solve problems in their communities. My project, in collaboration with Harshil Hari and Maria Mishechkina is an anti-procrastination app called Not Later, which seeks to build good study habits for students early on by discouraging procrastination. The app is a gamified to-do list that allows students to set tasks and earn parent-determined rewards for completing them. Overtime, as the due date approaches, less stars are earned for completing a task based on a linear function, encouraging students to do their tasks ahead of time. This algorithm halves the amount of stars earned if the student completes the task late. Parents approve tasks and create rewards and determine task star values. The app uses React Native, Firebase, and Expo, and is supported on all platforms. This app aims to help Middle School to Elementary students and their parents.
