Hi, I’m James Stevenson

I’m a Software Engineer and Security Researcher – I’ve worked in roles from penetration testing, low level development, vulnerability research, and more. Checkout the below to see what I’m up to!



Public Speaking

From around 2017 I’ve been speaking at security conferences across the UK, on topics from security operations, predicting cyber crime and terrorism, and on how to break into the computer security industry!


In 2021 I released my first book with Apress publishing, Android Software Internals Quick Reference. If you work with or find programming and Android interesting please consider picking the book up for yourself!

Later in 2022 I also self-published a ‘Mobile Offensive Security Pocket Guide‘ for Android and iOS reverse engineering and penetration testing!


Training Courses

I’ve released an Android reverse engineering course inspired by my interest in game design. This course walks through the fundamentals of reverse engineering and uses Android games as a fun and practical starting point.



Free and premium resources, available on everything from Android and iOS security fundamentals, reverse engineering basics, and study guides for my Udemy courses.
