Case study

GreenAir

Overview

GreenAir operates digital services for electric-vehicle and charging stakeholders, with workflows spanning CO₂-certificate management, customer information and partner operations in Germany and Austria. The product needed a secure, adaptable platform that could handle changing data, external partners and transaction-driven processes.

Elite Station’s contribution focused on cloud-native service design and delivery automation—giving the business a clearer foundation for evolving regulated and partner-connected workflows.

Technologies

Application services: Node.js and Express.js
Cloud and data: MongoDB and AWS services including EC2, Lambda and RDS
Platform engineering: Docker, Terraform, API Gateway and CloudWatch

Our contribution

Cloud-native service delivery: Designed API Gateway-managed service endpoints and Dockerized Lambda workloads to support independently deployable capabilities and demand-aware operations.
Service boundaries: Implemented private service-to-service communication patterns that keep internal traffic separate from public-facing interfaces and support clearer security controls.
Flexible data management: Used MongoDB for diverse operational data such as vehicle and customer records, with an architecture suited to evolving business data models.

Our contribution

Automated delivery: Implemented GitHub Actions workflows integrated with AWS tooling to make deployments more consistent and repeatable.
Infrastructure as code: Used Terraform to define and provision the cloud resources that underpin the service architecture, making environments easier to reproduce and change safely.
Operational visibility: Integrated AWS CloudWatch monitoring and alerting so the team can observe service health and respond to issues with more context.

Client benefits

A cloud-native foundation for evolving EV and partner workflows, with clearer boundaries around operational services.
Repeatable infrastructure and deployments that reduce friction when introducing product changes.
Better visibility into service health and diverse operational data, supporting more informed day-to-day decisions.
