Founded in 2018 with its first office in the Paris region, Elruba builds custom mobile, web, and desktop applications for clients across finance, business management, and e-commerce. Development covers Android and iOS mobile apps, web applications built from A to Z, and desktop software for Windows, Linux, and macOS, with teams organized around these industry specializations rather than a single generic offering.
Web projects run on PHP, .NET Core, Django, and Node.js, while mobile builds use Kotlin, JavaScript packages, and Flutter. Software development draws on C#, Java, Electron, and Python, and game projects are built with Unreal Engine, Unity, Godot, and Blender. A separate cybersecurity practice handles malware analysis, digital forensics, and web penetration testing, extending the company's work beyond application builds into security assessment.
Based at 231 Rue Saint-Honoré in Paris's 1st arrondissement, Elruba has completed more than 40 projects for over 30 customers across four-plus years of operation. The range of technical stacks in active use, from .NET Core and Django on the web side to Unreal Engine and Unity for game work, points to a company built around several parallel technical teams rather than one standard delivery process.
