Allegro is the most popular Polish shopping destination with about 17 million users monthly and over 1.1 milion items sold on the platform daily. We are most of all a marketplace where companies can sell their products but auctions are available as well. In 2015 we started our own e-tail operations and they are constantly growing, adding more complexity and scale to our platform. Allegro is also getting more and more mobile, with over 47 million mobile searches monthly and over 130 thousand items bought on mobile devices every day.
Making a site like this work requires a lot of engineering and as the site grows, we learn and adopt new technologies. What started out as a huge monolithic application is now migrating towards an ecosystem of loosely coupled microservices written in Java and other JVM languages running in the cloud. Creating a scalable and distributed system at this scale brings about many challenges which make our work interesting.
On allegro Tech we share some of the interesting things we do, the issues we face and the lessons we learn (sometimes the hard way). Software development is not only about technology but also about people, so we have a Tech section and an Agile section as well. We hope you find these posts useful. Feel free to get in touch and comment.
