Worked on the thoughtspot/visual-embed-sdk repository to deliver the ListPage V3 Default Experience, focusing on aligning the embedded analytics SDK with cluster-level feature flags. The update removed the hardcoded listpageVersion parameter, enabling the embed to default to ListPage V3 based on the LaunchDarkly flag, while maintaining an explicit revert path for backward compatibility. This approach improved cross-cluster consistency and reduced deployment drift, supporting safer incremental upgrades. The work demonstrated practical application of TypeScript, front end development, and testing skills, emphasizing feature flag-driven development and careful management of versioning within a complex, customer-facing SDK environment.
