Build and maintain growth-focused product features and analytics. Own data stack (PostHog, BigQuery, DBT, Metabase), run experiments to improve funnel and activation, ship full‑stack improvements across frontend and backend, and create growth loops to increase adoption and expansion.

Own and ship full-stack product features end-to-end for an open-source LLM observability platform: design specs, implement frontend and backend work (TypeScript/React, ClickHouse, Python), talk to users, write docs, and improve developer experience while collaborating in a small engineering team.
