Mywin.lk is a lottery buying service that lets customers in Sri Lanka purchase lottery tickets through the website, by SMS, or over a phone call — with subscription options that deliver lotteries automatically every day. It removes the friction of physical ticket buying while keeping every channel Sri Lankan customers actually use.
I lead the development of the platform for the client: a scalable React web application with a NestJS backend, integrated directly with the Sri Lanka National Lottery Board to enable real-time lottery purchases and subscription services, backed by PostgreSQL.
The solution includes an admin portal built on Strapi for content and operations, and is deployed on AWS with real-time transaction management and operational monitoring — giving the client full visibility over sales, subscriptions and delivery.
