Senior Flutter developer architecting secure mobile crypto wallets, marketplaces, and scalable blockchain-backed apps.
IndiaWhat I'm looking for
I’m a Senior Flutter Developer who architects production-ready mobile experiences, especially where security and blockchain mechanics matter. Recently, I architected and deployed a secure self-custodial crypto wallet app as a solo developer, including wallet generation, token/NFT management, DApp transaction signing, and cross-chain bridging—reaching 10k+ users in production.
I also build full-stack systems that move fast without sacrificing reliability. I authored a pure-Dart blockchain SDK used across 3+ internal projects, led a Polygon meme-coin marketplace with live analytics and buy/sell flows (optimistic UI + commit polling), and served as technical lead on a social content-to-earn app handling 100k+ daily interactions with OAuth/webhook verification, ERC-721 tokenization, and fiat payouts.
