Hello there!

My name is Aleksandr Litreev. I am an IT entrepreneur, software engineer, blockchain enthusiast & cybersecurity specialist.

How to get in touch with me?

Follow me on Twitter & Instagram. If you need to send me a message — send me an email to [email protected] or drop me a text on Telegram. If there’s something important you’d like to share — maybe you should encrypt it with my public PGP key.

Here are most social media I’m present in — feel free to verify my profile if someone is contacting you pretending to be me. If it is not there — it’s 99.99% scammer.

NB! I never do any sort of giveaways of crypto, and will never DM you first. Be careful.

What do I do?

Here is what I’m currently working on and where I am involved. The main subject of my interest are blockchain technologies, cybersecurity and digital human rights — most of my projects are all about it. By the way, if you like what I do — feel free to donate & spread the word.
