Blockchain Developer
Blockchain Engineer specializing in Solana on-chain programs and Web3 infrastructure.
I architect and ship production-grade Solana applications, including DeFi products, NFT platforms, and cross-chain integrations, with real users on mainnet. My work spans Anchor-based program design, token and NFT minting pipelines, security reviews, and full-stack blockchain systems.
I founded and independently built Dropsome, a Solana dApp enabling walletless SOL transfers via magic-links, handling the full lifecycle from on-chain architecture to deployment and operations. I also led Solana-side engineering for a cross-chain RWA NFT platform, focusing on on-chain program design and token/NFT flows.
Earlier in my career, I worked across mobile, embedded, and backend systems, where I designed authorization systems, real-time data pipelines, and reliable device-integrated applications. This background strongly influences how I build robust, user-centric blockchain products today.
Comfortable with global remote roles and flexible compensation structures, including salary or contractor payments in fiat or stablecoins.
