ABOUT THE PROJECT

A global provider of viewer interaction and monetization technology for TV, mobile, and web platforms needed a dedicated QA partner. Their product — an interactive overlay solution — powers audience engagement and monetization for content providers worldwide, supporting use cases from children's educational content to live advertising.

Business Objectives

01 — Ensure platform stability and consistent functionality across all supported devices and operating systems.

02 — Validate interactive overlay content against design and requirement standards.

03 — Test server capacity under high user loads to confirm infrastructure meets acceptance criteria.

04 — Improve QA and development workflows through better documentation and cross-team collaboration.

Process Overview

Regression & Smoke Testing — Built test suites to validate app functionality before each release across all supported platforms.

Cross-platform Debugging — Set up and operated debugging workflows in Android Studio, Xcode, Tizen Studio, and WebOS IDE, including simulator support for faster defect isolation.

Performance Testing — Developed load testing scripts in JMeter and K6, deployed on Azure and AWS virtual machines to benchmark server behavior under peak load.

Documentation & Collaboration — Rebuilt product and technical documentation in Notion; established structured communication between QA, development, DevOps, design, and business teams.

Challenges & Solutions

Challenge 1 — Server stability under load The platform required consistent low-latency connections during high-traffic events. We modeled real-world peak conditions using JMeter and K6, running tests on provisioned cloud infrastructure until we identified the failure threshold and confirmed the system met acceptance criteria.

Challenge 2 — Cross-platform functional consistency Interactive content had to behave identically across a fragmented device ecosystem. We addressed this through systematic cross-platform test suites and expanded debugging tooling that reduced time-to-isolation for device-specific defects.
