Experience
Classified Web App
A Python/Django-based application that allows end users to publish their advertisements digitally to millions of people. The users maintain control of the entire lifecycle of their ad from first placing it to the product being purchased.
Hyperlocal eCommerce App
Worked with a hyperlocal eCommerce startup that aggregated all local shopkeepers on its platform and allowed end-users to buy from the nearest shop online. I created APIs for mobile apps and web apps to consume. I got the opportunity to work on this project end to end, which involved designing, developing, and deploying the system on production.
Marketplace for Home Products and Experts
An eCommerce for mobile. I worked on developing content and a community-powered eCommerce app for home products. The app would serve as an online content-driven interior designer and furniture marketplace. This company is inactive.
Using Web Scraping to Get All Meta Information About Cars and Dealers
A web scraping tool that I built to extract comprehensive meta information about cars and their associated dealers. This tool gathers details like car make, model, features, and dealer contact information by systematically parsing relevant data from various websites. This scraped data is then stored in a structured format within a MySQL database, creating a centralized and organized data repository. Finally, I created a user-friendly Django dashboard that visualizes the data, making it easily accessible and explorable.
Developed an Automation Test Framework for a Group of Sites
A test automation framework that I built using Selenium to streamline testing across a group of similar websites. This framework enables the selection of random options throughout various pages within each site and verifies the resulting responses against predefined expectations. This approach ensures consistent and efficient testing, minimizing manual effort and increasing test coverage of critical features.
