Education: Master’s degree in Computer Science, Engineering, or a related field (or equivalent professional experience).
Microservices & Architecture: Deep understanding of system design and architecture, particularly with microservice architectures, and the ability to make decisions that ensure scalability and reliability.
DevOps & CI/CD: Hands-on experience with modern DevOps best practices – including version control, automated testing, and CI/CD pipelines – to accelerate development and deployment cycles.
Containerization: Proficiency with containerization and container orchestration tools, especially Docker and Kubernetes, for building and managing scalable applications.
