• Leveraging message brokers like RabbitMQ and Kafka to implement efficient asynchronous communication between services.
• Integrating with and managing data storage solutions, with a focus on performance and reliability.
• Implementing observability best practices by using monitoring and logging tools to ensure system health, stability, and transparency.
