Senior mobile engineer with 7 years shipping production apps — React Native, Swift, Flutter. Currently building a multi-chain MPC crypto wallet (Fireblocks, WalletConnect v3, 50+ blockchains). Before that shipped 4 consumer apps at Pushflow with 400K+ combined installs. Co-founded a mobile agency delivering 10+ apps for EU & US clients. I own the full cycle: architecture → native modules → CI/CD → App Store. Practice AI-driven development (Claude Code, MCP protocol) to ship fast with small teams. Comfortable going deep into native code (Swift/Kotlin) when JS/Dart hits platform limits.
