Brian Barak developed an A/B testing experiment for the statsig-io/docs repository, focusing on optimizing the signup call to action through dynamic configuration of button text and destination URL using Statsig. He addressed a race condition in experiment data fetching by introducing a custom useExperiment React hook, which coordinated Statsig values and stabilized the initial render. This approach ensured reliable CTA rendering during loading states, reducing UI flicker and inconsistency. Working primarily with JavaScript, TypeScript, and React, Brian established a maintainable pattern for future experimentation, improving the potential for data-driven engagement optimization on the documentation site within a single month.

July 2025 — Delivered a data-driven signup CTA experiment for the docs site and hardened reliability around experiment data fetch and rendering. Key feature: A/B test with dynamic configuration of CTA text and destination URL via Statsig, enabling data-backed engagement optimization. Fixed a race condition in initial render by introducing a useExperiment hook to coordinate Statsig values, ensuring stable CTA rendering during loading. Impact: Improved potential signup conversions through a configurable, experiment-driven UI; reduced initial-load flicker and UI inconsistency; established a maintainable pattern for future Statsig-driven experiments on the docs site. Technologies/skills demonstrated: React hooks and custom useExperiment hook, Statsig experimentation and feature flags, A/B testing design, and reliable UI rendering in a live docs environment.
