Balloons: Bitcamp Hackathon 2022 Winner

Balloons was my Bitcamp 2022 Hackathon project, it won multiple prizes including The Major League Hacking Special Recognition Award and Most Entertaining Project. Balloons is a custom built nerf turret capable of shooting items out of the air. We used OpenCV for locating the projectile then a series of regression models to predict its trajectory. Pyserial and C++ was used to interface and control the turret's Arduino.

Recaptcha V2/V3 Token Generator

Recaptcha V2/V3 Token Generator

My Recaptcha Token Harvester is a proof of concept project used for artificially triggering and solving Recaptcha puzzles so that the solve tokens could be harvested and saved for later usage. It utilizes a Flask API for storing tokens and managing concurrent harvesters, and Electron.js for HTTP request interception and modification. It works on both Version 2 and 3 puzzles as well as any website regardless of security.

SpeakEZ Web Security

SpeakEZ Web Security

SpeakEZ is my own take on creating a Web Application Firewall that takes inspiration from many WAFs I've reverse engineered and solved such as Akamai, PerimeterX, and Datadome. It utilizes an array of browser, hardware, and mouse movements fingerprinting which is then judged on its human-likeness by a neural network written with TensorFlow.
