Work on prompt engineering, model selection and routing (Haiku / Sonnet / Opus), and workflow optimization.
Build evaluation and regression frameworks for AI workflows to prevent model-upgrade regressions.
Create lightweight dashboards for engineering leads to surface delivery patterns and bottlenecks.
Own initiatives end-to-end: scope → design → ship → measure → iterate.
