Christian Vari's Portfolio Resume on the Web
Software Engineer, Blockchain Auditor, Blockchain Consultant, Codezen Founder, Owner and Lead Engineer

About Me

Hey there

I’m Christian Vari, a 28-year-old Italian software engineer and security researcher passionate about blockchain technology and distributed systems.

I’m the Founder & CEO of Codezen SRL, where I lead audits and research focused on blockchain security. I also serve as Lead Security Researcher at Oak Security, Security Researcher at Zenith Security, and Chairman of Altairith Capital Holding SRL.
As a mentor at DeFi Talents (Frankfurt School of Finance & Management), I enjoy helping the next generation of professionals grow in the Web3 space.

My work centers on securing smart contracts, chain code, and protocols across Solana, Cosmos SDK, Polkadot/Substrate, and EVM ecosystems. I spend most of my time analyzing complex systems, uncovering hidden vulnerabilities, and improving security processes through deep code understanding and research.
My technical toolkit includes Rust, Golang, Solidity, TypeScript, CosmWasm, Cosmos SDK, Substrate/Ink!, Solana/Anchor, Move, Soroban, Docker, and Kubernetes.

Beyond security, I’m deeply interested in microservice architectures, developer experience, and how AI-driven tooling can assist security audits without compromising code quality or confidentiality.

When I’m not working on audits or research, I like exploring new places, building side projects, and helping teams design systems that are both scalable and secure.

If you’d like to get in touch, head to the contact section below, I’d love to hear from you.
