Designed and optimized secure backend services in Rust for a blockchain-based airdrop application featuring games, auctions, and lotteries. Implemented major system optimizations that decreased response times and curtailed bot attacks, enhancing overall platform integrity. Architected a high-performance PostgreSQL database layout supporting efficient query execution and processing for datasets of 5M+ rows. Developed and audited secure smart contracts for EVM, Solana, and TON blockchains, ensuring code security and reliability. Engineered a multiprocessing AI agent system for code generation, involving sophisticated prompt design and fine-tuning.

Designed and implemented features for spot and futures trading smart contracts on the NEAR blockchain. Participated in the architectural design of an EVM rollup (L2) to serve as the foundation for a scalable, off-chain orderbook system.

Engineered backend services for calculating key financial metrics, including PnL, and built custom blockchain indexers for efficient on-chain data retrieval. Developed a novel ETF smart contract on the EVM blockchain and created functional prototypes for arbitrage bots to interact with it. Conducted in-depth data analysis to model strategies, prove concept viability, and demonstrate product profitability.
