Summary

What I did

• Replaced inconsistent manual YAML configurations for pages, templates, and components with a UI-driven workflow.
• Developed a system to provide users with UI visibility into the success status of their configuration pushes.
• Conducted user feedback sessions with product operations teams to diagnose workflow issues and transition them from manual VS Code editing to the internal tool.

Results

• Implemented server-driven UI where schemas were written on the backend and the frontend generated forms dynamically.
• Resolved GitHub sync issues by moving from direct commits to a queued user branch system with a pull request trigger.
• Implemented a retry mechanism with backoff for GitHub API calls to handle rate limits and timeouts.
• Integrated a live simulator preview directly into the authoring tool to provide real-time rendering of changes for product operations teams.
• Introduced human-friendly validation checks to clarify errors for non-technical users.
• Developed a synchronized dual-editing system allowing users to switch between UI forms and direct YAML editing without runtime errors.
• Eliminated engineering dependency for 90% of routine content updates.
• Reduced configuration errors by 70%.
• Cut average rollout time from days to under 30 mins.
• Reduced post-release UI bugs by 60%.
• Reduced time-to-launch by 65%.
• Supported 15+ campaigns per quarter across 5 regional markets.
• Managed configuration schemas for around 78 organisms, including widget-cards and image-carousels.
• Tool used to build or edit 97-98% of pages, templates, and components within the Careem app.
• Output of the tool reaches millions of Careem app users across 5 regional markets.
