Profile

Full-Stack Developer with 8+ years delivering production-ready digital products. Strong across the entire stack — from scalable backend systems and REST APIs to polished frontend experiences in React and Next.js. Deep expertise in WordPress and WooCommerce, including complex plugin architecture, performance engineering, and third-party integrations.

Rare combination of Web2 and Web3 capability: equally at home building high-traffic web platforms as architecting smart contracts, NFT systems, and blockchain-integrated ecommerce. Operates effectively at both technical leadership and hands-on execution level, with a consistent focus on clean architecture and long-term maintainability.

▸ Rare hybrid Web2/Web3 capability — production experience across both worlds
▸ Proven track record integrating blockchain with traditional platforms at scale
▸ Comfortable across architecture, backend systems, and frontend delivery
▸ Experienced working independently and within collaborative team environments
