- Deep understanding of database management principles, indexing, and query optimization for big data.
- Experience with asynchronous programming, concurrency, and task queues (e.g., Celery, Redis).
- Ability to write clean, logical, and reusable Python code, focusing on performance and scalability.
- Familiarity with containerization tools such as Docker and orchestration with Kubernetes is a plus.
- Proficiency in version control systems (Git) and collaborative development workflows.

- Excellent communication skills and ability to work within a team-oriented, agile environment.
Nice-to-Have:
- Experience with other Python web frameworks (Django, Tornado).
- Knowledge of data pipeline tools, ETL frameworks, or big data technologies (e.g., Spark, Hadoop) is a plus.
- Familiarity with cloud-based databases or large-scale database management (e.g., AWS RDS, Google Cloud SQL).
