I'm an Smart Contract Security Researcher and DeFi Developer focused on understanding, building, and securing blockchain protocols. I’m actively learning by auditing real-world code, reproducing vulnerabilities, and developing tooling for secure smart contract development.

I’m currently open to work and looking to collaborate with teams working on innovative DeFi projects or security-focused Web3 infrastructure.

• 🔐 Security Researcher: Focused on auditing smart contracts and uncovering vulnerabilities.
• ⚙️ Smart Contract Developer: Building and testing with Solidity and Foundry.
• 🔬 Hands-on Learner: Reproducing historical exploits and studying real audit reports from leading firms.
• 🌐 DeFi Enthusiast: Deep interest in AMMs, lending protocols, and economic attack vectors.
• 🧠 Constantly Evolving: I believe Web3 security is an ongoing challenge—and I'm here to keep up.

• Languages: Solidity
• Security Tools: Slither, Echidna, Aderyn
• Testing & Dev: Foundry, Docker
• Other Tools: Git, VS Code, Markdown
• DEFI: UniswapV2, UniswapV3, Curve, Aave V3, GMX
• Soft Skills: Fast learner, self-driven, collaborative

I'm always looking to grow and improve my skills. Currently, I'm deeply focused on blockchain technology and actively working on projects that enhance my understanding of this rapidly evolving space.
My goals include learning the inner workings of decentralized systems, including:

• Security protocols
• Feature development
• Real-world application functionality

You can check out my GitHub repository to see the projects I'm working on to transition into the blockchain industry.

Each project is focused on building secure, efficient, and innovative decentralized applications—leveraging my technical growth to create meaningful contributions to the ecosystem.
