Hi!
I'm a professional embedded software developer with over 10 years of real-world experience. During my career, I've conducted numerous reverse engineering tasks, which also included dealing with recovering information from a number of embedded devices.
I've dealt with eMMC modules before (they are fairly easy to read). I can lead you through the process and explain the intricacies involved.
I've cofounded Warsaw's Hackerspace, I'm a member of London's one, frequent visitor to CCC (Chaos Computer Congress) which is Europe's leading security and forensics conference, gave a talk about in-depth Android, etc.
I live in London, I'm fluent in English, I've TA'd engineering courses before so I can express my thoughts clearly.
Best Regards,
Tomasz
