Description

  • Own and evolve the iOS technical architecture for Aave App, balancing rapid development with security and maintainability.
  • Design and ship blockchain functionality including wallet creation, key management, transaction signing, gas estimation, RPC interactions, onchain reads, and account-abstraction flows.
  • Lead integration of onchain and offchain data across savings, funding, withdrawals, bridges, vaults, portfolios, notifications, and analytics.
  • Set standards for Swift and UIKit code quality, testing, observability, performance, release safety, and incident response.
