  • Strong experience building production backend systems with Django and asynchronous python (asyncio)
  • Strong fundamentals in algorithms, data structures and concurrency
  • Experience in architecture design of highly loaded and scalable solutions
  • Hands-on experience with relational databases (PostgreSQL), including writing complex SQL queries, schema design, migrations, performance tuning
  • Experience with Redis for caching and state management in distributed systems
  • Strong understanding of the development cycle from requirements analysis and deployment to application monitoring
  • Willingness to participate in on-call rotations
