Hi, I'm João Antunes. I'm a passionate computer scientist specializing in cybersecurity and software development. Recently, I've been working as a Malware Analyst and Reverse Engineer at Cognizant in Lisbon, where I dive into Android apps to detect malware and help improve platform security. I also have teaching experience as an Assistant Professor where I guided undergraduates in Network and Computer Security labs. With a strong background in programming languages like Python, Java, C#, and C++, and skills spanning from reverse engineering to game development, I enjoy solving challenging problems in distributed systems and security. I’m eager to continue growing in roles that let me leverage my technical expertise and mentoring abilities.
