🛡️ Smart Contract Security Engineer | Solidity Specialist
🎓 MCA Cybersecurity Student
✍️ Security Blogger | Competitive Researcher

I’m a Solidity & Smart Contract Security Engineer actively participating in:

• 🧪 Security competitions
• 🐞 Bug bounties
• 🔍 Smart contract vulnerability research

I enjoy breaking systems to understand them better — and then writing about it so others don’t repeat the same mistakes.

• Smart contract auditing & threat modeling
• Vulnerability discovery & exploit analysis
• Protocol-level thinking (EVM, transaction flows, edge cases)

Currently expanding into:

• 🧠 Zero-Knowledge Proofs (ZK)
• ₿ Bitcoin protocol fundamentals

Strong

• 🟢 Solidity (EVM internals, gas, storage, security patterns)

Comfortable

• 🟡 JavaScript
• 🟡 TypeScript

Security Stack

• Foundry
• Hardhat
• Slither
• Mythril
• Manual auditing & PoC writing

I regularly write security-focused blogs on Medium:

• Smart contract vulnerabilities
• Attack vectors & mitigations
• Deep dives useful for fellow security researchers

📚 Goal: make complex security concepts clear, practical, and reproducible.

• Deepen expertise in protocol & low-level blockchain security
• Transition Ethereum security knowledge into Bitcoin research
• Contribute to open-source security tooling
• Participate in Bitcoin & protocol-focused internships

• Smart Contract Security
• Zero-Knowledge Proofs
• Blockchain Protocol Design
• Open-Source Security Research
