Enrico Teotti

Most recently, I built ensemble classifiers combining heuristics, TF-IDF ML, and multi-step LLM chains that increased recall from 0.69→0.95 and F1 from 0.78→0.90 with no added LLM spend, reducing manual review from 1,000 jobs/day to 90. I re-architected an inherited 80-prompt LLM pipeline with evals, auditability, and per-attribute error tracking, and reduced p95 latency from 32s to 600ms using Sentry, PostHog, and production-replica diagnostics.
