What I'm looking for

I'm seeking senior engineering roles where I can lead blockchain and web application development, optimize smart contracts, and mentor teams—ideally at security-focused, innovative, remote-first companies.

I am a senior full-stack engineer with 7+ years building web applications and blockchain solutions, having led technical projects and teams across startups and freelance engagements. I built an AI-powered web page builder, a Telegram Mini App for Garmin integration, and optimized smart contracts using low-level Yul/Assembly for improved gas efficiency.

As CTO I launched an options trading protocol for live DeFi markets, implemented Chainlink oracle integrations, and established deployment pipelines and security practices for smart contract infrastructure. I focus on pragmatic, secure engineering—combining frontend, backend, and blockchain expertise to deliver production-ready systems.
