Work Experience
Web Security Researcher
Freelance
- Found multiple web vulnerabilities on apple.com and icloud.com, including XSS, CSRF, and token leakages, receiving multiple payouts due to the severity of these bugs.
- Used web debuggers effectively to debug AngularJS template injection vulnerabilities.
- Developed own tooling in Python to aid in vulnerability discoveries, in addition to tools such as Shodan, Nmap, and sqlmap.
iOS and Back-end Developer
Freelance
- Generated income and sales by releasing Autocart independently to the App Store.
- Consulted clients based on the success of Autocart on how to programmatically perform automated checkouts.
- Developed multiple apps and prototypes using Swift for iOS and TypeScript for Node.js. Deployed to the App Store and web.

Experience
Autocart
http://autocart.pageI developed the traversal and item manifest system to perform fast checkouts in an automated manner with Swift, JavaScript, and WebKit. The app uses Combine, PromiseKit, and SwiftUI. Modular MVVM design enables testability and changing different checkout execution engines in real time.
