Custom Software & .NET
Business applications, cloud services and robust backends built with C#, .NET and ASP.NET Core — designed for reliability, clarity and future growth.
INDEPENDENT SOFTWARE ENGINEERING · EST. 2005
For more than 20 years, we have designed, built and evolved reliable software — from complex business platforms to focused applications that solve a specific problem exceptionally well.
We turn demanding requirements into practical, maintainable systems.
WHO WE ARE
Mobi Mouse is a software engineering company based in Belgrade, Serbia. Since 2005, we have been building software that helps organizations manage operations, connect systems and turn data into useful tools.
Our work combines software architecture, hands-on development and long-term product ownership. We are just as interested in making an existing system faster and more reliable as we are in building something new.
Whether you need a large, integrated platform or a smaller custom application, we focus on clear requirements, thoughtful design and software that remains useful after launch.
The right solution is not always the biggest one. It's the one that fits the problem.
WHAT WE DO
We design and deliver the application, data and integration layers that modern businesses depend on.
Business applications, cloud services and robust backends built with C#, .NET and ASP.NET Core — designed for reliability, clarity and future growth.
Data modeling, SQL development, performance tuning, migrations and reliable data workflows with Microsoft SQL Server and MySQL.
REST APIs, integrations with third-party platforms, data exchange and modernization of existing systems — so information moves where it is needed.
Mobile applications with polished user experiences, native platform capabilities and cross-platform .NET delivery where it makes engineering sense.
Node.js services, interactive web interfaces and modern frontend development using JavaScript, TypeScript and Vue.
Architecture, deployment and ongoing improvement of applications running on AWS, Linux and modern web infrastructure, with attention to performance and maintainability.
OUR TECHNICAL TOOLKIT
Our experience spans the entire lifecycle of business software — from database schemas and high-performance APIs to mobile interfaces, deployment, monitoring and production support.
Scheduling, CRM, invoicing, inventory, communications and operational reporting.
