Proof-of-concept tool that exploits a weakness in Guilded's account creation, showing how its registration flow could be abused at scale.
hi.
i'm
simonx.
I'm a beginner programmer based in Italy. I am currently studying multiple languages, such as C++ and Python.
about me
ideas into real projects.
I'm a developer who likes to learn by building: always experimenting, always turning ideas into something that actually runs. I write Python, C, C++, JavaScript, HTML and CSS, and I work on both the frontend and the backend of the web.
Programming led me into cybersecurity, mostly penetration testing and network analysis: finding out how real platforms can be abused, and showing it with working proofs of concept. Away from the keyboard I'm a competitive debater, which is where I learned to research fast and explain clearly.
- 4+ years programming
- 2 years in pentesting & network analysis
- 3 years of competitive debate

selected work
security & automation
Fast message sender for NGL with a built-in, optimised proxy checker, used to stress-test the platform's anti-spam and rate-limiting protections.
Automation tool that drives the Odoo web interface with Selenium, taking repetitive tasks off people's hands.
My solutions to OLINFO training problems for the Italian Olympiad in Informatics: algorithms, data structures and a lot of edge cases.
