ERC20 Token— Standard Token Development
Developed custom ERC20 token smart contracts with enhanced functionality beyond the standard implementation. I architected gas-optimized Solidity contracts incorporating features such as minting mechanisms, burn functions, transfer restrictions, and access control systems. The contracts were designed with security best practices, including reentrancy guards and safe math operations, ensuring robust protection against common vulnerabilities. Each implementation was thoroughly tested and optimized for deployment across Ethereum and EVM-compatible networks.

Swape — Cross-Chain Token Swap
Swape is a decentralized token swap protocol where I developed smart contracts enabling cross-chain exchanges between Ethereum and Polygon. I architected gas-optimized Solidity contracts handling token swaps with automated liquidity management and secure bridging mechanisms. The implementation ensures optimal swap rates while maintaining robust security for cross-chain transactions, creating a trustless solution for moving assets between ETH and POL ecosystems without centralized intermediaries.

Melonverse is a desktop metaverse gaming platform where I designed the complete blockchain infrastructure powering NFT-driven gameplay. I developed and deployed NFT contracts, marketplace contracts with auction mechanics, voting systems, and staking pools all gas-optimized and security-hardened. I then integrated these contracts into Unity3D, creating event-based on-chain interactions that improved player engagement while keeping blockchain functionality seamless and non-intrusive. The marketplace smart contracts and auction systems I built drove significant growth in transaction volume. By handling both Solidity development and Unity integration, I delivered an end-to-end Web3 gaming solution where digital ownership and gameplay are genuinely interconnected.
