Identified areas of improvement in our pre-submit pipelines that help in validating code changes.

End-to-end tests were split across multiple pipelines because they required different backend configs. Implemented a strategy to consolidate all end-to-end tests to be covered by a single pipeline. With this we were able to run same number of end-to-end tests as before but with far fewer compute resources.

Introduced a new pipeline to build reusable artifacts whereas previously each pipeline use to build artifacts before running actual tests.

Built tooling such that when validation pipelines are re-tried they only run tests that failed previously instead of running entire suite of tests.

It helped us reduce overall resource usage to save infrastructure cost. Failure rate for the pre-submit validation pipelines also reduced because of lesser load on the system which in turn helped in improving developer confidence in the system as the number of false negatives where pipelines use to fail due to unrelated issues have reduced significantly

Proposed and developed architecture to allow feature teams to decouple their code from rest of the Front End application by creating a Micro Front-End app for their feature.

This facilitates feature teams to have full control over their codebase and allows them to manage it better

The micro frontend app exposes react components that can be lazily loaded and simply plugged into the parent application

Developed CLI tool “create-ts-app” to allow developers to bootstrap a new micro frontend with all recommended tools

Started initiative to share work done by Front-End Infra team in form of monthly newsletters. This ensured that 70+ front-end developers at Thoughtspot always stay up-to-date with the improvements that our team is adding to make developer experience world class

Setup mocking of graphql responses during integration testing using apollo library

Developed frontend and Graphql layer for a feature to allow filtering of data from UI based on conditions added by the user.

Setup a new app along with development tools, react, typescript, vite bundler, dependency-cuiser, eslint, css-modules, etc

Proposed and implemented architecture for the new app to be used as a library inside the old AngularJs app which. Using this architecture we were able to slowly phase out components from the old app one at a time replacing them with components from new React app, fully migrating to the new app in the process.

Setup internationalization using react-i18n library and documented best practices on the topic for the rest of the Frontend team to follow.

Setup graphql in the app using apollo library.

Developed an architecture that decouples the Thoughtspot web application from other micro-services.

Even though every customer runs the application on their separate instance, this new architecture allows updating the web application for any customer cluster using a central release management tool.

Improved the loading speed of Thoughtspot web application by a factor of 5 and reduced the size of the application by 30% without sacrificing any functionality.

Designed and developed front-end and back-end for the help customization feature, which allows admins to modify the content displayed in Help Section inside the Thoughtspot web application.

Developed a monitor feature where users can opt to monitor certain business metrics inside Thoughtspot application and will get notified via an email once there is a change in any of those business metrics.
