About Me
Blockchain Developer & Security Researcher building trustless protocols on EVM chains.
I’m Thomas Sorza (Sh4dEx), a Blockchain Developer and Security Researcher with a strong focus on smart contract development and auditing. I’m currently pursuing a degree in Systems Engineering and Computer Science at UPTC (Universidad Pedagógica y Tecnológica de Colombia).
My passion lies at the intersection of decentralized systems, cryptography, and security. I believe that building secure and trustless protocols is one of the most important challenges in modern software engineering.
What I Do
- Smart Contract Development — Writing and deploying secure contracts on EVM-compatible chains (Solidity, Foundry, Hardhat).
- Smart Contract Auditing — Identifying vulnerabilities such as reentrancy, integer overflow, access control issues, and more.
- Security Research — Exploring attack vectors in DeFi protocols, on-chain forensics, and exploit analysis.
- Systems Engineering — Building robust backend systems with a focus on performance and reliability.
