I build marketplace platforms from the ground up—custom vendor flows, split commissions, escrow logic, and role-based dashboards built around the exact business model, not plugin limits. I also develop custom NFT marketplaces with Web3 and blockchain integration, including wallet connections, smart contract interaction, and minting logic. When issues arise, I trace them to the source—fixing stuck withdrawals, commission errors, API conflicts, and database inconsistencies. I focus on clean architecture, stability, and long-term reliability.
