Solana Developer | Rust | Web3 | Trading Bot

Experienced Blockchain Engineer specializing in blockchain development, with a focus on Solana, Rust, and Web3 technologies. I have extensive expertise in designing and deploying decentralized applications (dApps), writing efficient smart contracts, and building scalable blockchain solutions. My technical stack includes Rust, Anchor Framework, Solana Program Library (SPL), Web3.js, and Truffle, combined with full-stack tools like React.js, Next.js, Node.js, and GraphQL/Prisma.

I have a deep understanding of blockchain protocols, including Solana's Proof-of-History (PoH) and Ethereum's EVM, enabling me to create low-latency, gas-efficient systems. My work spans across DeFi platforms, NFT marketplaces, and cross-chain integrations, where I optimize smart contract performance and ensure robust security practices through techniques like fuzz testing, formal verification, and auditing.


With hands-on experience in integrating blockchain solutions into user-friendly interfaces, I excel in bridging on-chain and off-chain systems to deliver seamless Web3 experiences. I am passionate about driving innovation in the blockchain ecosystem by leveraging cutting-edge technologies to create secure, scalable, and efficient decentralized solutions.
