UX/UI Design

Based on Node.js and the Pug template engine, this software is a URL shortener with pixel tracking and an iframe overlay. Users can hide their original URLs with short URLs and add extra tracking pixels to the short URL for retargeting ads. The software is a helpful tool for marketers who spend a lot of money on social media ads. I designed the UI/UX and built the project with Node.js and the Pug template engine.

Software Architecture

Adspider is a web application based on React and PHP that shows users archived and active Facebook ads with detailed information like geography, likes/reactions, comment numbers, and gender distributions. This is a comprehensive tool that helps advertisers to evaluate the Facebook campaigns by analyzing competitors ad campaign. The software is created as a WordPress plugin, but most of the work done on the front end was React-based. UI Design: The UI design was done using Figma then converted into HTML/CSS for the implementation. Front-end Framework: I used React/Redux for the web application with lazy loading and performance optimizations. The client managed the Facebook Ads API.
