Risk | End-to-end Fraud Management System

This is a React-based dashboard for fraud analytics. The app was slow and cumbersome to use and develop. I initiated a long-term incremental migration to React to systematically improve the platform's UI/UX, developer experience (DX), and speed.

Here is what I achieved after completing the migration:

• Decreased the app load times from about five to ten seconds to one to two seconds.
• Decreased the app bundle sizes from 7MB to 200KB and 100KB per page bundle size.
• Decreased the app build speed from five minutes to 30 seconds.
• Improved user experience with load times and feature clarity as well as added delightful and snappy interactions.

Hex | Global Developer Platform

A React-based platform that allows for international teams to create internal applications such as a dashboard that monitors Star Citizen's in-game entities using WebGL, developer build artifacts and pipelines, and more—all the while maintaining a cohesive design language.

Glossi

A Next.js-based dashboard for managing advertising assets, uploading models, and creating projects. It includes a real-time Unreal Engine-powered app for creating advertisements using predefined scenes and models.
