Summary
👤
Senior🎓
Top SchoolWeber Tsai is an Information Security Engineer based in Taipei with 11 years in software and security, including over seven years specializing in reverse engineering and three years in malware analysis. He combines low-level expertise in C/C++ and Windows/Linux internals with application development in C#, Java and web back-end frameworks like PHP/Laravel and Node.js, enabling him to trace issues from binary artifacts to server logic. At CHT Security he applies that cross-stack fluency to practical defensive and investigative work, while his open-source contributions—such as enhancing MapleLib for MapleStory file handling and WZ→NX conversion tools—show a knack for file format reverse engineering and animation data repair. Colleagues would note his curiosity for new techniques and an uncommon blend of game file tinkering experience with professional threat analysis skills.
