Rehn is a small medical device software company operating across Windows (.NET/C#), mobile (iOS/Android via Flutter), and backend (Python/PyTorch/TensorFlow) stacks. The balanced engineering-sales-support structure reflects a regulated hardware-software hybrid business model, while the project backlog—product launches, regulatory certification, adverse event management—shows the company is navigating medical device compliance workflows rather than building pure software infrastructure.
Rehn develops software components for medical devices, with active engineering work spanning desktop applications (.NET), mobile platforms (iOS/Android), and embedded AI systems (PyTorch/TensorFlow/OpenCV). The company operates in China with approximately 6 employees across engineering, sales, and support functions. Current focus areas include new product development, design iterations on existing offerings, international trade show participation, and managing regulatory compliance—including medical device registration certification and adverse event reporting systems that are central to their operational risk surface.
Backend: .NET/C# with Entity Framework Core and SQL. Frontend: Vue and web technologies (JavaScript, TypeScript, HTML/CSS, Webpack). Mobile: Flutter, iOS (Objective-C), Android (Kotlin). AI/vision: PyTorch, TensorFlow, OpenCV. Infrastructure: Linux, Git.
Medical device regulatory compliance (certification and registration), adverse event communication and reduction, quality system maintenance, customer satisfaction, and meeting international certification requirements.
