Hi there 👋

📫 Looking for someone to audit your Smart Contract? 📫

Drop a line to @jcr_auditor in Telegram or email me at [email protected]

I have been breaking things professionally since early 2016. My whole career has been focused on offensive security with a strong background doing pen-testing of "traditional" stuff like web, mobile, or cloud, but since 2021, I have been working full-time as a Smart Contract auditor.

In addition, I lecture on Solidity/EVM security to 🌱blockchain students🌱 at some institutions and give workshops/talks on the topic occasionally.

Current expertise:

CosmWasm (Rust) [⚡⚡⚡⚡⚡]
Solidity/EVM [⚡⚡⚡ 🪲 🪲]

🔍🔓 Security engineer at Matter Labs/zkSync and available for "private audits" as a freelance security researcher as well.

👓📚 Teaching Smart Contract security at University of Malaga and IEBS bussiness school
