• Familiarity with caching mechanisms (Redis, Memcached) to optimize performance.
• Experience with Docker and microservices-based architectures is a plus.
• Good understanding of API design, authentication mechanisms (JWT, OAuth), and security best practices.
• Experience working in Agile environments and using Git-based version control.

Nice to Have:
