  • Good knowledge of version control tools (Git) and CI/CD workflows
  • Exposure to DevOps tools and cloud deployment (e.g., Firebase, AWS, Fastlane) – basic level
  • Excellent communication skills and fluent English (Upper-Intermediate or higher) – must be able to interact directly with clients
  • Familiarity with security and compliance standards in healthcare (HIPAA, GDPR) is a plus

Nice to have:
