Ship to Android, iOS, and Web from One Kotlin Codebase.
Tired of maintaining separate codebases for every platform? Ernst & Conte is a Swiss consultancy that helps teams consolidate their mobile and fullstack development with Kotlin Multiplatform. We handle architecture, engineering, and project bootstrapping — so you reduce duplication, cut costs, and deliver faster.
Engineering Services for Your Project's Success
Whether you are launching a new product or modernising a legacy stack, we bring the technical depth to move your project forward:
Kotlin Multiplatform
Stop paying for two separate mobile teams. We architect and build shared Kotlin codebases that target Android, iOS, desktop, and web — reducing maintenance overhead while keeping native performance.
App Development
From greenfield builds to feature extensions, we deliver production-ready Android and iOS applications. Native when it matters, cross-platform where it saves you time and budget.
Fullstack Development
Backend APIs, frontend interfaces, cloud infrastructure, and CI/CD pipelines — we own the full delivery chain so nothing falls between the cracks.
Swiss eID Integration
Prepare your platform for the Swiss eID framework. We provide architecture consulting and hands-on implementation so your business meets compliance requirements on schedule.
