Project Overview

VIAVI Solutions is a global leader in network test, monitoring, and assurance solutions. I developed a comprehensive web-based recording system for their optical measurement devices to streamline troubleshooting processes and enhance technical support capabilities.

The Challenge

Technical support teams needed a way to quickly reproduce client issues with optical measurement systems. The existing process was manual and time-consuming, making it difficult to provide efficient support and troubleshoot complex measurement scenarios.

My Role

As the lead developer, I designed and implemented both the web-based recorder interface and the file management API, creating a complete solution for recording, storing, and replaying measurement system actions.
