About
Hi, I am Johnny, a passionate cybersecurity expert with over 12 years of experience working across both government and private sectors. My journey in the world of blockchain began in 2013, and since then, I’ve navigated through almost every crypto cycle. In 2020, I shifted my focus to DeFi and blockchain security, launching my YouTube channel “JohnnyTime” where I share educational content.
I’m the creator of the famous comprehensive Smart Contract Hacking course. I also founded Ginger Security, having secured protocols of such renowed companies as Starkswap and Revelator.
You can find my insights and educational materials across platforms like YouTube, Medium, LinkedIn, and Twitter. Let’s connect and explore the fascinating world of blockchain and cybersecurity together!

"Wow, what a game-changer! 🚀
I just completed Part 1 of @RealJohnnyTime's Smart Contract Hacking Course.
Over 20 hours of video in Part 1, and lots of hands-on coding exercises. Highly recommend for anyone interested in Web3 and smart contract security research or auditing.
As someone just starting into the Solidity Smart Contract Security world, I found the course to be a godsend and well worth the small investment. It's been easy to follow, even for a newbie like me.
What I love most? The hands-on approach! 🛠️ Not only did I get to dive deep into the theory, but I got my hands dirty writing Solidity code and running tests using the Hardhat Framework. It's like learning to swim by diving right into the deep end (with floaties, of course 😉). Johnny's detailed code walk-thru's were awesome.
This course is your golden ticket if you're keen on diving into Web3 and smart contract security. 🎫
Just a heads-up: having some experience with Solidity beforehand will help.
Highly recommend! 🌟🌟🌟🌟🌟

"Not sure if you saw but usage was so good this week that our servers went down for a bit today. Which in my view is amazing. So thank you again for the work!"
