  • Flutter (Android & iOS)
  • React.js / Next.js
  • Node.js backend architecture

This role requires someone who can think architecturally, execute independently, and deliver within tight timelines.

Key Responsibilities

1. Backend Architecture & API Development (Node.js)

  • Design scalable REST APIs
  • Build booking engine logic (seat inventory, availability sync)
  • Implement concurrency-safe seat reservation system
  • Develop OTA integration architecture
  • Integrate payment gateways & refund logic
  • Implement reconciliation module
  • Design role-based admin APIs

  • Logging, monitoring & error handling
  • Performance optimization

2. Mobile Application Development (Flutter)

  • Performance scaling configuration

5. AI-Assisted Development

  • Use AI tools (ChatGPT, Copilot, etc.) to accelerate development
  • Rapid debugging
  • Code optimization
  • Automated documentation
  • Intelligent testing support

We expect smart usage of AI — not dependency without understanding.
