Solidity Developer

Built an AI-driven on-chain execution engine enabling automated blockchain operations across multiple EVM networks through a unified interface. Designed and implemented end-to-end transaction workflows for token swaps, cross-chain bridging, transfers, and smart contract interactions. Developed Solidity smart contracts with full lifecycle support including generation, deployment, verification, and upgrade handling. Architected multi-chain system supporting Ethereum, BNB Chain, Polygon, and other EVM-compatible networks with modular execution layers. Engineered AI-based intent parsing system to convert natural user inputs into structured on-chain transactions. Integrated secure wallet management, transaction signing flows, RPC optimization, and gas-efficient execution strategies. Built scalable Node.js + TypeScript backend for orchestration, transaction routing, and distributed state management. Focused on production reliability, failure recovery, and secure execution of high-value on-chain operations.

Architected and developed a full-featured DeFi swap platform (Ryoshi Swap) within the Cronos ecosystem. Designed and deployed smart contracts for AMM-based token swaps, liquidity pools, staking, and reward distribution systems. Implemented liquidity add/remove flows with optimized gas usage, secure pool logic, and real-time on-chain updates. Built staking and incentive mechanisms with dynamic reward distribution based on liquidity contribution and token holdings. Developed cross-chain bridge integration enabling asset transfers and improving interoperability across networks. Integrated Web3 frontend (dApp) with wallet connectivity, transaction signing, and live interaction with deployed smart contracts. Improved protocol reliability through secure contract design, transaction validation, and failure-safe execution flows.

Designed and deployed over 20 ERC-20 and ERC-721 smart contracts on Ethereum, Polygon, and BNB Chain, optimizing gas efficiency by up to 35% through Solidity best practices and upgradeable proxy patterns. Conducted end-to-end smart contract security audits for 10+ client projects, identifying critical vulnerabilities including reentrancy attacks, integer overflows, and access control flaws, delivering detailed audit reports with step-by-step remediation guidance. Architected and deployed DeFi protocols handling multi-million dollar TVL, including liquidity pools, staking mechanisms, and yield farming contracts with automated reward distribution logic. Led cross-chain Solana development using Rust and Anchor, shipping production programs covering NFT minting, token vesting schedules, and PDA-managed account systems across a 4-person engineering team. Served as the primary technical point of contact for international clients, translating complex blockchain requirements into scalable, auditable smart contract solutions delivered on time and within scope.

Engineered the full smart contract architecture for an NFT Esports League on Solana, supporting on-chain match verification, verifiable asset ownership, and automated reward distribution across thousands of players. Deployed 10+ production-grade smart contracts using Rust and the Anchor framework, covering NFT minting, token management, competitive game logic, and player ranking systems, maintaining a near-zero critical bug rate post-launch. Designed and implemented a token-based reward economy for the esports ecosystem, including on-chain prize pool distribution, staking incentives for active players, and automated royalty mechanics for NFT creators. Built a real-time Web3 frontend integration connecting Solana smart contracts to a React-based UI, enabling seamless wallet connectivity, live transaction signing, and instant on-chain state updates for end users. Represented the team at the Solana Hackathon (August 2022) with the Keila project, architecting and delivering a fully functional blockchain prototype end-to-end within 48 hours, competing against 350+ international teams. Collaborated closely with a cross-functional team spanning smart contract development, frontend engineering, and game design, serving as the sole blockchain lead responsible for all on-chain architecture decisions.

Took on blockchain development responsibilities as an early career move into Web3, contributing to the core technical foundation of Poly186 from day one as a founding team member. Wrote and deployed the P8 token smart contract on Gnosis chain, gaining hands-on experience with ERC-20 token standards, tokenomics design, supply mechanics, and on-chain governance integration. Implemented and launched the P8 liquidity pool on a decentralized exchange, learning and applying automated market maker logic, liquidity incentive mechanisms, and price feed integrations in a live production environment. Contributed to the early architecture of the Polyverse platform, a multi-chain Web3 ecosystem, working across smart contract development, wallet integration, and cross-chain compatibility under senior technical guidance. Developed NFT minting contracts and metadata standards for the Poly186 collection, ensuring on-chain provenance, royalty enforcement, and compatibility with major NFT marketplaces as a first hands-on NFT project. Participated in internal smart contract review processes, building foundational security awareness around common vulnerabilities and pre-launch audit routines that shaped a security-first development mindset going forward.
