A GPU-accelerated path tracing engine written in C++ using the OpenGL API. The engine is capable of rendering complex scenes with physically-based materials and lighting with built-in temporal denoising, anti-aliasing, and HDRI lighting support.

My journey into ray marching, a technique for rendering complex 3D scenes using signed distance functions (SDFs). Or, how a script I wrote on my calculator to pass time in class kickstarted my passion for graphics programming.

A research project exploring the use of generative adversarial networks (GANs) for generating high-fidelity textures from low-resolution images, completed as my final project for Columbia's Neural Rendering course.

My writeup for the 2Password challenge from the LA CTF 2025 cybersecurity competition, where I exploited a format string vulnerability in a C program to leak program memory.

My writeup for the Loadall.js challenge from the KalmarCTF 2025 cybersecurity competition, where I used Return-Oriented-Programming (ROP) to exploit a JavaScript engine.

My writeup for the "Lost Pyramid" challenge from the CSAW CTF 2024 cybersecurity competition qualifiers, where I used a JWT implementation flaw to gain access to a hidden flag.
