6. Solid understanding of server environments, deployment automation, and cloud infrastructure (AWS, Azure, or similar).

7. Familiarity with frontend technologies (HTML, CSS, JavaScript) and their integration with backend systems.

8. Strong problem-solving and analytical skills, with the ability to troubleshoot complex production issues.
