About

With 7+ years in blockchain spanning Ethereum mining, smart contract development, and DeFi architecture, I build blockchain solutions that bridge the gap between crypto innovation and real-world utility. From smart contracts to fintech apps, I create systems that work for users in challenging markets.

At Mundo Wallet, I transformed a crypto wallet into a fintech application for high-inflation, restricted-currency markets. This included virtual card integration, blockchain infrastructure optimization that cut costs by 60%, and smart contract improvements for scalability.

My blockchain expertise spans Solana and Ethereum ecosystems, including payment integrations with Solana Pay, DeFi protocol design, and infrastructure optimization. I focus on building secure, cost-efficient solutions that deliver real business value.
