  • Proficient with databases (MongoDB or relational) and schema/design trade-offs
  • Familiar with service design principles, APIs, and mobile-app backends
  • Strong problem-solving, ownership, and communication skills
  • Nice to have: Java experience, GCP exposure, prior freelancing/startup experience
Benefits
