A European aggregator company came with a request to create a platform where users can receive electricity tariff change suggestions based on their payment data. The app should be available for iOS and Android. An admin functionality for user management and a chat for support requests should be implemented
Our team successfully completed all the tasks assigned to us. In the first phase of the application development, we implemented the client and administrator APIs, developed the mobile application, set up CI/CD processes, and deployed 3 environments using the infrastructure as code approach
The new system helped businesses and individual clients cut their electricity costs by an average of 15–20% thanks to real-time usage tracking and smarter tariff recommendations. Push notifications and automated alerts boosted engagement rates by over 30%, while the provider reduced manual support requests and positioned itself as an innovative leader in digital energy services







A B2B platform was developed for analyzing current electricity payment data and generating tariff change suggestions if a more favorable option is found
A user verification and identity confirmation service was developed for the platform
A mobile application for iOS and Android was developed
Notification services (email, push) were implemented


We engineered the solution from scratch, creating a robust API and data structure to support tariff analysis, developing mobile apps for iOS and Android, and building a web admin interface for account management. Service communication ran through Azure Service Bus, with APNS and FCM powering push notifications and an SMTP provider enabling email integration. The infrastructure was provisioned with Terraform, ensuring secure, scalable deployments and seamless operations
