• Built the initial version of Zulip SaaS infrastructure comprising of billing and subscription system. Integrated Stripe with Zulip, implemented upgrade and card change flows, and added restrictions on message history and upload space. Developed a tool that automates the generation and maintenance of hundreds of Stripe fixtures.
• Proposed, built, and launched Zulip one-click app in the DigitalOcean marketplace. One-click app made it super easy to start a Zulip server up and running on DigitalOcean which boosted the number of Zulip production installs. I am the sole maintainer of this project.

• Reduced CI queueing time by ~10% and test failures caused due to CI issues by 80% by migrating testing infrastructure from Travis to a Docker-based infrastructure on CircleCI.
• Built tooling for migrating teams from Mattermost and Slack Plus to Zulip. The tool reduced the barrier to move data from Mattermost/Slack Plus to Zulip which resulted in an increase in the number of teams doing the migration.
• Built a GitHub action for the Zulip archive tool. This brought down the setup time of the Zulip archive from almost an hour to less than 10 minutes.
