  • Parallel/concurrent processing (multiprocessing, threading, asyncio) and performance tuning
  • REST API development with Django/DRF or FastAPI (auth, error handling, pagination)
  • ML fundamentals with scikit-learn; experience deploying models to services
  • Testing/quality: pytest/unit test, CI/CD, Git workflows; clear communication and documentation
