I build full-stack Web3, security, and high-load applications with TypeScript and Node.js and React.

I've built full-stack applications for dApplica, Boosty Labs, and NDA clients across Web3, security, and high-load systems. My work includes a 3D asset marketplace with Babylon.js, real-time blockchain listeners, scalable FastAPI microservices, and WalletConnect and Solana integrations.

At dApplica, I implemented smart-contract and play-to-earn staking mechanisms, automated AWS deployment workflows, and improved a 3D marketplace feature that increased asset purchases by 20% in its first month. I also rebuilt React UI flows with Zustand, contributing to an 11% increase in daily interactions and a 4.5% reduction in page abandonment.

More recently, I've migrated a high-load Rust backend into Nest.js, built a multibrowser fraud-prevention extension using transaction simulations, and developed an autonomous LangGraph workflow that turns OpenAPI specifications into reviewed documentation, integration tests, and TypeScript SDKs.
