Hands-on experience with RESTful APIs, microservices architecture, and third-party API integrations.

Advanced knowledge of MySQL (or other relational databases), including query optimization and schema design.

Proficiency in version control systems (Git) and experience with collaborative workflows (branching, pull requests, code reviews).

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

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

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

Excellent communication and leadership skills, with a proactive approach to mentoring and collaboration.

A passion for engineering excellence, continuous learning, and contributing to a culture of innovation and quality.
