About the project

Join the backend development team to build and maintain a large-scale web infrastructure on AWS, using Python, PHP, Node.js, MongoDB, DynamoDB, and MySQL.

Our team handles all stages of the software development life cycle—designing solutions, writing and testing code, and automating deployments. We collaborate closely with web, iOS, Android, QA, infrastructure, and product teams to deliver exceptional experiences for our users.

As our platform expands globally, we tackle challenges like distributed data storage and performance improvements. Besides developing new features, we are migrating from a monolithic application to microservices with Serverless Framework and AWS Services.
