Yosemite is an advanced pentesting tool designed to help users protect their Instagram accounts from unauthorized access. Utilizing Python Django and DRF for the backend, and Flutter for the user interface, Yosemite mimics real-world hacking techniques to test security. It provides a streamlined recovery process, achieving a 98% success rate in reclaiming compromised accounts. The integration of Stripe API enables secure subscription management, offering various service tiers. With over 750 users and a substantial monthly recurring revenue, Yosemite has proven to be a reliable and efficient tool for digital security. This project highlights my skills in developing secure, user-friendly applications with financial integration.
