Designing and building AI/LLM-assisted product features
-
Integrating LLM APIs into Ruby on Rails systems
-
Combining AI approaches with business logic, tests, fallbacks, and production safeguards
-
Owning features from technical design to production
-
Improving reliability, accuracy, consistency, latency, cost, security, and maintainability
-
Writing and maintaining automated tests, including unit, integration, and E2E tests
-
Debugging production issues and improving system behavior over time
