Building things that ship

Senior Full-Stack Engineer with a mobile-first background and deep expertise in Flutter and Dart. 7+ years across mobile apps, backend services, APIs and production fintech systems.

Currently at Block Labs, I work on Best Wallet, a multi-chain non-custodial crypto wallet with 100K+ active users: Flutter features across wallet, transactions, swaps and staking; Wirex card payments; backend contributions; and production debugging.

Before that, I spent four years shipping blockchain products at CoDeTech: CorePass (decentralised identity), XCB HODLER (official Core Blockchain wallet), and WebRTC-based communications. I use an AI-assisted engineering workflow (Claude, Cursor) for architecture, testing and documentation. Fluent in English and Persian.
