πŸ‘¨β€πŸ’» About Me

I'm a Blockchain Lead & Full Stack Developer with 7+ years of experience architecting and implementing cutting-edge blockchain solutions across multiple ecosystems. My journey in blockchain began in 2018, and since then, I've:

  • Pioneered cross-chain applications connecting EVM networks with Flow and WAX ecosystems
  • Architected high-performance NFT marketplaces handling millions in transaction volume
  • Developed innovative DeFi protocols with advanced staking and DAO governance mechanisms
  • Implemented secure smart contracts following industry best practices and security standards
  • Led technical teams across multiple blockchain projects from concept to production
  • Mentored junior developers in blockchain fundamentals and advanced smart contract development

My technical expertise spans the entire blockchain development lifecycleβ€”from writing secure smart contracts and building decentralized applications to integrating wallet solutions and implementing cross-chain communication protocols. I'm particularly passionate about creating blockchain solutions that solve real-world problems while ensuring security, scalability, and user accessibility.

Beyond coding, I'm an active contributor to the blockchain community through technical articles, open-source contributions, and participation in hackathons where I've earned recognition for innovative solutions.
