Experience

Shopify Website for a Mobile Accessory Company

A Shopify-based website with complete end-to-end checkout. I was the sole developer and developed the entirety of the website, from UI to animations and the email sign-up functionalities. The client wanted to develop this project as an independent theme that could easily be usable on similar company websites.

Super App for EV Enthusiasts

A React Native-based app built for EV enthusiasts with the following capabilities:
• Provides a way for users to view charging stations within India on the map.
• Users can also search for charging stations, with the nearest one showing up in the search results.
• A public chat group for users to interact, share feedback, and all things regarding EV.
• Users can ask questions and receive answers from fellow users who have dealt with the same problems.

Web Scraper for Scraping Data from Websites

A web scraper based in Python. The scraper gathers raw data from multiple websites and APIs, parses the data in the required format, and stores it in the database.

Since scraping is a time-consuming process, the scraper is optimized and broken down into multiple smaller tasks, each handling a part of the entire process and storing the output in an in-memory data store.

A Flask-based API Back-end Service

Developed and entire Flask-based API back-end service from scratch. The service is the main communicator for a React Native-based mobile app and a Next.js-based website. It also handles async tasks for dispatch emails and push notifications.

The project also had a permission-based admin dashboard for viewing, updating, and deleting records.
