"Code not just to build, but to empower. Learn not just to finish, but to lead."
I am a Full-stack software Engineer focused on building secure, scalable, and decentralized infrastructure. My work spans from writing low-level EVM opcodes and secure smart contracts to architecting high-performance backends and intuitive frontends.
- 🛡️ Focus: Smart contract security, defensive programming, and EVM exploit development (CTFs).
- 🏗️ Building: Modular Web3 protocols, localized fintech solutions, and AI-driven platforms.
- 💻 Environment: Strictly building and debugging in a Linux terminal.
- 📝 Writing: Occasionally breaking down complex Web3 concepts, React hooks, and EVM mechanics into digestible technical content.
