João, a data and software engineer at GitGuardian, is deeply involved in the internal monitoring product team, API development, and open-source tools. His interest in software development began in high school with creating bots for browser games using Python and C#, eventually leading him to explore Linux and low-level programming. João's venture into the open-source community is marked by his popular project "yay," an AUR helper for Arch Linux, which gained traction despite minimal promotion, showing his commitment to maintaining and developing projects. His cybersecurity interest was piqued during university, particularly through external activities and his involvement with HackerSchool, a student group focused on technology exploration, which eventually led him to pursue a master's thesis in cyber-security. João was drawn to GitGuardian by its challenging technical environment and mission, allowing him to work on impactful projects and maintain open-source initiatives, while his personal interests include playing rhythm games and hiking.
