Hi, I'm Blockchain expert

Senior Blockchain Developer & Web3 Architect specializing in DeFi protocols, smart contracts, and decentralized applications that shape the future of finance.

About Me

I'm a Senior Blockchain Developer from Obrenovac, Serbia, with deep experience building secure and scalable decentralized systems. Over the past 5+ years, I've designed and deployed 50+ smart contracts, securing $5M+ in TVL, and architected blockchain solutions across DeFi, NFTs, crypto bots, and Web3 gaming.

Whether it's launching yield strategies, optimizing gas fees, building custom bots, or crafting Web3 mini-games, I bring a full-stack mindset with a security-first approach. Let's build the future of blockchain—securely and creatively.
