Product Analytics SQL Queries
Translates product questions into battle-tested SQL for funnels, user retention cohorts, DAU/MAU stickiness, and event analytics.
The Product Analytics SQL Queries skill transforms business and product questions into precise, production-grade SQL across major dialects including Postgres, BigQuery, Snowflake, and DuckDB. Rooted in Lean Analytics methodologies, it specializes in the four foundational product data patterns: conversion funnels, cohort retention curves, active-user stickiness ratios, and event volume aggregations. By enforcing structured Common Table Expressions (CTEs), strict denominator anchoring, safe handling of incomplete cohorts, and automated sanity-check protocols, this skill prevents common analytical bugs like inflated user counts and recency bias, making it indispensable for product managers and analysts auditing metrics or building trustworthy dashboards.
