# Heather Thacker
Making performance testing practical and approachable for modern engineering teams.

## About

Heather Thacker helps teams build resilient systems by bringing performance testing into their everyday workflows. Drawing from her background writing code, she builds content at Gatling that compares textbook DevOps theory with the messy reality of production software.

She focuses on turning system reliability into practical steps. Breaking down non-deterministic LLM architectures, her talk on [load testing AI](/videos/1914-load-testing-ai-aiming-at-a-moving-target) showed why traditional API methods fail and how to properly measure token generation latency to prevent runaway costs.
