  • Strong capability in iOS architecture (end-to-end thinking, best practices, maintainability)
  • Hands-on experience with real-time systems on mobile (WebSockets, Streaming/live data processing, Reliability patterns (reconnect strategies, state management, error recovery)
  • Strong engineering judgment: knows when pragmatism beats perfection without sacrificing quality
  • Ownership mindset: can execute independently, anticipate edge cases, and raise overall engineering standards
  • Clear communication, including the ability to explain why decisions are made and document standards
  • Comfortable leading and mentoring freelancers/developers with clarity and respect
  • “Leadership without ego” — raises the bar through standards, coaching, and hands-on example

• Act as Swift Tech Lead (set the technical direction for iOS: architecture decisions, code quality standards, performance, scalability, and best practices, define and document coding paradigms and structural standards for the mobile codebase)
• Reliability and real-time connectivity (make the app resilient and reliable — especially around real-time workflows, WebSocket lifecycle (connect/reconnect, ping/pong, backgrounding, timeouts, streaming/ live data processing, robust error handling and recovery), ensure strong networking and authentication flows, including edge-case handling (e.g., 401/token refresh patterns)
• Scale the product (drive the next phase of growth: stability, performance, UX polish, and feature expansion — fast execution with high craftsmanship, build foundations that allow adding engineers later without sacrificing quality)
• Lead the mobile team (take over and lead an existing team of freelancers (and/or transition away from them as needed), providing technical guidance, clear direction and code review standard, hands-on leadership and delivery)
• Expand to Android in future (iOS is the priority; help lay the groundwork for Android with a coherent mobile strategy, if experienced, contribute to Android/Kotlin direction or enable faster Android ramp-up)
