Behavioral STAR Interview Story Polisher

### The 90-Second STAR Script - **Situation (15s)**: At my previous company, our VP proposed rewriting 8 core services into Rust to improve service response times. However, our team had zero production Rust experience. - **Task (10s)**: As the Lead Architect, my responsibility was to ensure we did not derail our roadmap for marginal gains without empirical validation. - **Action (45s)**: Instead of arguing theoretically, I spent two days profiling our production traces and discovered that 85% of our latency came from un-indexed PostgreSQL queries, not language runtime speed. I built a prototype comparing an indexed Node.js service against a Rust service. The difference was under 3ms. - **Result (20s)**: I presented the telemetry to our VP. We canceled the rewrite, saving an estimated 6 months of developer time, and achieved a 40% latency reduction simply by refactoring our database queries.
