source equivalents like Kafka and RabbitMQ.

  • Design and optimize data models and database interactions.
  • Ensure application quality through testing, code reviews, and best engineering

practices.

  • Integrate AI/ML models into production systems, working closely with data

scientists and AI engineers.

  • Collaborate with cross-functional teams to translate business requirements into

technical solutions.

  • Participate in architecture discussions, technical decision-making, and

continuous improvement.
