Architected ArchiveMatter, an NFT marketplace and fractional-ownership platform, end-to-end, with Fastify/Node.js services, MongoDB schemas, Redis/BullMQ workers, on-chain event listeners, and release scheduling, from requirements to production.

Architected PinnaclePay, a fintech application backed by ClearBank APIs, and implemented the direct debit feature and all other account-related operations. Architected MyQi, an AI Crypto Financial intelligence application with custom AI model deployment, proper instruction engineering, and prompt engineering, which lets users decide which crypto to buy or sell in a competitive market.

Led blockchain delivery across 3 concurrent product lines: DeFi arbitrage, NFT staking, and a gaming marketplace, coordinating a distributed team across Dubai, Russia, and the US through sprint planning, code review, and release coordination. Built a high-throughput on-chain execution engine integrating multiple third-party DeFi protocols; the platform processed 48K+ transactions within 3 months of launch. Owned the transaction pipeline: pre-submission route simulation to reject unsafe or unprofitable transactions, retry and failure-recovery logic, and real-time on-chain event indexing feeding monitoring and reporting.
