Employment
Experience
- BookMyShow: Web App and Progressive Web App (PWA) | 2017https://in.bookmyshow.com
As a full-stack developer, I built a React Redux web app and PWA using Node.js/Koa middleware for booking movie and concert tickets, reviews, trailers, and events.
I designed a configuration-based workflow to integrate existing booking flows and maintain the old PHP and jQuery-based application. The pages were optimized for quick schedule access and easy bookings with minimal steps. - Payments and Checkout
I integrated a React front end with payment service providers (PSPs) in different countries.
I created self-service upgrades for current customers to switch to better packages. To improve conversion rates, I designed a monthly subscription flow. Additionally, I built an add-on marketplace that enabled existing customers to buy add-ons without upgrading their packages. - Microlending Web App
I developed a microlending and maintenance web application using React.
I created a shared architecture for multiple projects to provide clients in various countries with easy access to loan management. I led a team of five, responsible for designing the client-side application using React and Node.js middleware. Additionally, I implemented structured logging and reusable lambda functions for alerting based on logging metrics for microservices.
