Rockstar🎓
Top SchoolFrancesco Tamagni is an Android/iOS security research engineer and seasoned reverse engineer with 11 years of experience focused primarily on iOS platform internals. At NowSecure he combines hands-on vulnerability research with tooling improvements, contributing deep fixes and features to high-impact open-source projects like Frida and radare2/rizin that power dynamic instrumentation and binary analysis. His work spans low-level system programming—handling Mach-O, dyld caches, hardware breakpoints, and Stalker instrumentation—demonstrating a strong grasp of OS internals and concurrency issues. Francesco often tackles subtle, brittle problems (race conditions, stack alignment, backtracing) that are critical for reliable runtime analysis on Apple platforms. Trained as a computer engineer at Politecnico di Torino, he brings both academic rigor and long-term practical experience in security tooling and reverse engineering.
