Senior Mobile Engineer @Cake Labs

Remote | April 2023 - Present

• Lead multi-chain integrations across the Cake Wallet platform, adding Solana, Tron, Polygon, Base, Arbitrum, and BSC. Refactored the EVM and L2 chain code into a reusable architecture so new chains ship in days instead of weeks.
• Own WalletConnect and dApp connectivity across EVM and Solana. Built session handling, expired-session recovery, deep links, and a full UI redesign; migrated to the Reown package. Three years of continuous ownership on a critical user-facing surface.
• Designed and shipped Solana from scratch: SPL token support, on-chain implementation, Token-2022 standard, passphrase support, NFT integration, and Jupiter DEX aggregator for in-app swaps.
• Re-architected wallets into a seed-based WalletGroup system supporting passphrase-derived sibling wallets, lead-wallet routing, and backup/restore compatibility. A major refactor that touched nearly every wallet feature.
• Built the production integration test suite using the Robot pattern, covering wallet creation, restore, send, exchange, transaction history, and credential confirmation flows. Runs in CI on Android and iOS.
• Shipped TOTP 2FA from the ground up (setup, rotation, preset toggling, bypass protection), plus scam-detection for ERC-20 contract addresses, EOA-vs-contract validation on send, and iOS bio-auth handling.
• Performance and infrastructure: migrated trade storage from Hive to SQLite, migrated to Etherscan v2 API, built automatic node-switching for slow-network conditions, and optimised Monero blockchain scanning.
