Turn-In

TJHSST's Code Autograder

Previously, teachers in TJHSST CS classes had to test student code manually. For example, they would collect student code through an LMS, run the code on their computer, and then analyze the results. They would repeat this process per student, per period, per assignment. As you can imagine, this is both time-consuming and risky from a security standpoint (what if a student submits malicious code?).

Turn-In solves this problem by enabling functionality for code autograders. All a teacher needs to do is write the grader script for an assignment, and students will be able to submit their code to Turn-In for grading. Turn-In will run the grader and give students instant feedback, allowing students to learn from their mistakes while saving teachers time and effort.

TJUAV GroundStation

An Open-Source, Performance-Driven Implementation of Ardupilot

The go-to Ardupilot Ground Control Station (GCS) is Mission Planner, an application that supports a variety of features including configuration, mission planning, and live telemetry. However, it's a Windows-only application, and all attempts to run it on Linux have resulted in a buggy mess. Additionally, performance issues result in frame rates as low as 0.2 FPS, which is unacceptable for something as crucial as a GCS.

TJUAV GroundStation solves this problem by interfacing directly with MAVLink messages from telemetry radios, providing a lightweight, fast, and cross-platform implementation of a GCS. It supports almost all of Mission Planner's features, and arguably implements them better.

HackTJ Portal

A Privacy-Focused, FERPA-Compliant Hackathon Submission and Judging Platform

Previously, HackTJ, an annual student-run high school hackathon, used Devpost to manage its project submission and judging needs. However, just mere months before our scheduled event, our school district (Fairfax County Public Schools) banned the use of Devpost due to privacy concerns. This left the HackTJ team scrambling to find a replacement platform that was both privacy-focused and FERPA-compliant.

To help solve this problem, I spent the next few months developing and deploying the HackTJ Portal, a custom submission and judging platform that met all of our needs. It passed FCPS's security scans and privacy reviews with flying colors, and gave us the secure district-approved hackathon platform we needed.
