Ad Moderation Tool

A single-page application (SPA) to moderate the ads posted by advertisers; a reviewer uses this tool to review an ad package and approve or reject them manually. Advertisers can appeal on behalf of any ad that they feel was incorrectly flagged. Reviewers can then review, add, and grant or reject the appeal.

The application has various personas like admin, manager, reviewer, and advanced reviewer. The users with the role admin, manager, or advanced reviewer can also perform bulk actions. They can directly approve or reject a whole package of ads or directly make a decision on fraud customers.

I built the UI and APIs for the application as well as the build and deployment pipelines. The UI was built using React and Redux with the Fluent library; the designs were done in Figma.

I worked mostly on building the UI components, writing the REST APIs, integrating APIs, E2E testing, and developing the build and release pipelines (CICD) using Azure DevOps. Apart from core development, I also led a team of four engineers.

Admin Analytics

A web application that shows a range of analytics to the admin user for several products—Power Apps and Power Automate. The analytics were built using Power BI custom visuals using D3.js for charts and jQuery data tables for the grid.

The whole app was built using React and Redux. Few examples of analytics modules are "Top Users of Power Apps in Mobile Devices," "Top Users of Power Apps in the US Region," and "Top Connectors Used in Power Automate," and so on.

I was involved in building the screens for all modules and worked on making the application accessible.

Car ECU Analyzer

A React-based web application where all different ECUs for a car were shown. After selecting an ECU, the features were then listed in the left-side navigation and the user could select a single feature or select all the features and see the context and structure view of the ECUs.

In the context view, a graph is displayed with box nodes and signals from ECUs were shown as directed lines connecting the nodes. In the structure view, a parent ECU box is shown along with the child boxes within them—it went n-level deep considering all the ECUs available.

I built the whole app; the UI was built in React, state management was done in Redux, and Bootstrap was the UI library. The graphs and charts were built using D3.js and SVG. We implemented unit tests using Jest and the APIs with Node.js and Express.js.

This application was built for one of the top automobile companies.

Ecommerce SaaS

https://webware.io
An eCommerce SaaS-based product that allows users to sign up and create an online store.

I created the web application from scratch along with the major modules, including the product page, cart page, admin side theme, and template customization.

Loving Tan

A Shopify store for a company with a top-selling tanning cream.

I built the store in Shopify and theme customization, including the "buy one get one free" private customized application for the store. I also developed a customized private bundles application for the store and a customized discount application for the store.

Loving Tan Wholesale

A Shopify store where the company can manage the wholesale sales for invite-only users and sellers of a brand of top-selling tanning cream. Wholesale customers can create orders in bulk after logging in.

I built the whole store and created a Shopify private app to customize it for users who received different wholesale discounts.

Sisters The Label

https://au.sistersthelabel.com/
I made a few theme customizations to the theme for the Shopify store "Sisters the Label," including the landing page.
