  • Write clean, modular, and testable code following OOP principles.
  • Diagnose and resolve production issues efficiently.

  • Working knowledge of JWT, OAuth2, and backend security.
  • Basic understanding of GraphQL, gRPC, and CI / CD pipelines.
  • Experience with Docker Compose, Nginx, or GitHub Actions.

    • Preferred Qualifications :
