Experience Highlights

Raydium - Decentralized Exchange (DEX) on Solana

As a blockchain developer on Raydium.io, I contributed to smart contract development, Solana blockchain integration, liquidity pool optimization, and security audits. I optimized smart contracts for secure transactions, developed protocols for enhanced Solana interaction, and improved liquidity pool performance with stability algorithms for market volatility. Additionally, I conducted security audits to fix vulnerabilities, ensuring the platform’s security. These efforts reduced latency, improved scalability, and enhanced the user experience.

Optimism - Layer 2 Scaling Solution for Ethereum

Contributed to Optimism as a blockchain dev: wrote/audited Solidity contracts for L2 bridges, batching, and fraud proofs. Improved OP Stack (geth-based), built cross-chain messaging, and TypeScript tooling for deployment/tests. Upgraded sequencer and Bedrock migration. On frontend: built React UI, wallet connect, tx status, L1↔L2 logic, and governance flows. Solved calldata costs, upgradeability, chain switch bugs, and optimized dev/testing tools.

Aurory - Blockchain Architecture for Web3 RPG Game

Developed and maintained Solana smart contracts for Aurory, including NFT minting, $AURY staking, and marketplace logic. Built secure on-chain systems for dynamic NFTs, item fusion, and token rewards using Rust and Anchor. Implemented SPL-based trading with full validation and PDA access control. Optimized compute usage and wrote test coverage to ensure performance and security across the game’s blockchain features.
