Client background
Kreios is a Luxembourg-based outsourcing company with a strong track record in delivering custom software solutions for both government and commercial sectors. Since 2006, the company has been bridging local business needs with high-level global tech talent.
Project goals
The aim was to support Luxembourg’s digital transformation by building modern, efficient platforms for public services, such as employment portals and professional directories, tailored to specific administrative and end-user needs.
Business challenge
Public sector projects often involve complex requirements, strict compliance standards, and integration with legacy systems. Kreios needed to deliver flexible, scalable, and secure solutions while ensuring a smooth user experience for both citizens and administrators.
Our solutions
We developed and maintained several Django-based applications using a powerful tech stack including PostgreSQL, ElasticSearch, and AWS. Key features included advanced search functionality via Django Haystack, secure file management, robust API design with GraphQL, and asynchronous task handling with Celery. The infrastructure was containerized with Docker and deployed using AWS ECS for better scalability and uptime.
Value delivered
The platforms created by Kreios enhanced public access to employment information and professional guidance. The architecture allows for efficient data management, powerful search, and smooth integration with government systems, improving service delivery and administrative workflows.
Result
Kreios successfully delivered reliable, user-friendly solutions that are now actively used by government bodies and citizens across Luxembourg. These platforms support critical public services and demonstrate the company’s capacity to handle large-scale, regulation-compliant software development in the government sector.
