Chi sono
Python engineer and ethical hacker with 12+ years building automation, web scrapers, mobile apps and secure backends. I work as a Red Team Operator testing web apps, APIs and e-commerce platforms, and I once found a checkout flaw that let orders be placed without paying. I can help you: extract data from hard sites (anti-bot, proxies), automate browser tasks, build Flutter apps for Android and iOS, and find security holes before attackers do. Clean code, clear communication, on-time delivery. Message me before ordering. I reply fast.
