• Design, develop, and maintain scalable backend services using Python and frameworks such as FastAPI or Flask.

• Build and integrate RESTful APIs to support mobile application features, fan engagement functionalities, and digital service delivery.

• Implement AI-powered features by integrating services and models from providers such as OpenAI, Hugging Face, or similar platforms.

• Develop efficient asynchronous data flows and ensure reliable communication between application components and external services.

• Design, optimize, and maintain SQL and NoSQL databases to support performance, scalability, and data integrity.

• Implement secure authentication and authorization mechanisms, including OAuth2 and JWT, while following data privacy best practices.

• Containerize applications using Docker and support cloud deployment, preferably on Microsoft Azure.

• Contribute to CI/CD pipeline development, deployment automation, testing, and continuous improvement of development workflows.

• Collaborate with cross-functional team members to deliver reliable, user-focused solutions aligned with project objectives.

• Proven experience in Python development, ideally in building production-ready backend systems and scalable applications.

• Strong knowledge of FastAPI or Flask and experience designing and implementing RESTful APIs.
