Our team was involved in the full-cycle development of the Lucky Day app from scratch – a free mobile gaming app that allows users to win money and earn daily rewards by simply playing lotto, scratches and raffle games. As the product was growing, our client found it challenging to deliver software and security updates on a timely basis. As a result, they felt the urgent need to embed DevOps into the software development lifecycle.

We took on the following challenges:
Apply DevOps practices to a large-scale, mature project.
Design and implement build automation systems.
Set up a CI/CD pipeline.
Automate the provisioning, configuration, and management of cloud-based infrastructure.
Manage application security and set up role-based access control.
Implement data migration from multiple sources to ETL solution for data aggregation and visualization.


Implemented automated software build and packaging processes and test runs.
Set up an automated deployment process to automatically promote builds through the development pipeline – from development sandboxes to testing environments to production servers.
Reconfigured the existing infrastructure to improve its stability, scalability and security by implementing autoscaling services, security keys, RBAC and monitoring tools.
Managed application security through assigning different levels of access and permissions to specific roles and implementing best practices in information and data security.
Took on the challenging task of transferring data between systems, migrating data to data warehouses, and performing database backups.


Lucky Day achieved 5x faster software delivery and feature implementation.
Improved team efficiency with higher production and better quality.
By embedding DevOps best practices into the software engineering process, we helped Lucky Day to reduce technical debt.
By automating the parts that developers used to do manually, we were able to drastically reduce the potential for human error.
