  • Build GenAI features using LLM APIs, structured prompting, and orchestration frameworks such as LangChain, LangGraph, and DSPy.
  • Evaluate AI system performance using retrieval metrics, response quality assessment, hallucination analysis, latency measurement, cost analysis, and failure-case testing.
  • Understand engineering trade-offs across model quality, latency, cost, reliability, maintainability, and implementation complexity.
  • Own features end-to-end, from clarification and experimentation to deployment and initial support.
  • Translate requirements into user stories, provide implementation plans, and own features throughout the software development lifecycle.
  • Identify risks, dependencies, and data limitations early and propose workable solutions.
