Experience with Protocol Buffers and gRPC in Dart.
Track record of shipping and supporting large-scale mobile apps in production.
Fluency in RESTful API design, mobile CI/CD, and Git-based workflows.
Strong understanding of AI-driven development tools, including prompt engineering, LLM-based code generation, test writing, and code review automation.
