Your Gateway to Next-Gen IT and Software Solutions
Oronts is a Munich-based AI and software engineering company focused on building production-grade systems that run reliably and scale with real business needs. We design and deliver backend platforms, cloud architectures, and AI-driven systems across industries. Our work covers microservices, API platforms, event-driven architectures, and complex system integrations. We help companies structure, rebuild, and scale their technical foundation to support growth without creating long-term technical debt. Our services include fullstack development, backend engineering, DevOps, and cloud infrastructure on AWS and Azure. We build and operate containerized systems using Docker and Kubernetes, implement CI/CD pipelines, and ensure systems are secure, observable, and performant in production environments. A key part of our work is building intelligent systems. We design and implement RAG pipelines, document processing platforms, automation workflows, and data-driven decision layers. These systems are built with clear separation between data, permissions, logs, and model integration, making them suitable for sensitive and business-critical use cases. We also work with PIM, CMS, and commerce platforms, integrating them into unified architectures. This includes headless CMS setups, structured content delivery via APIs, and complex data synchronization between systems. Our approach is architecture-first. We focus on clean system design, clear boundaries, and maintainability. We don’t just deliver features. We create systems that can evolve, scale, and remain stable over time. We operate as a senior engineering partner, not as a pool of developers. We take ownership of architecture, backend systems, integrations, and platform stability. We often step into projects where systems need to be stabilized, restructured, or extended with new capabilities. We build systems that work in production, scale with the business, and deliver measurable impact.
