⚡ What I Build

🔐 Smart Contract Engineering

Designing & deploying production-grade contracts on Ethereum. Deep understanding of EVM internals, storage layout, opcode-level optimization, and contract upgrade patterns (Proxy, Diamond).

🏗️ Web3 DApp Development

Full-stack Web3 — React/Next.js frontends, Node.js backends, ethers.js/wagmi/viem integration, IPFS storage, subgraph indexing, and end-to-end production deployments.

🛡️ Security & Auditing

Checks-Effects-Interactions, reentrancy guards, access control, flash loan attack mitigation, and formal verification thinking. Writing exploit-resistant, battle-tested contracts.

⛽ Gas Optimization

Storage slot packing, custom assembly via Yul, unchecked math patterns, calldata optimization, and profiling with Hardhat Gas Reporter & Foundry snapshot diffs.
