• Experience with cloud platforms (AWS, GCP, Azure) and containerization technologies (Docker/Kubernetes)
• Experience with testing frameworks
• Strong analytical skills and a data-driven approach to problem-solving
• Excellent problem-solving skills, creativity, and the ability to work both independently and collaboratively
