Summary

AppBaumeister Collective is a senior-only development team specializing in mobile applications that scale.

Every member has 10+ years of hands-on experience building apps for DAX companies, streaming platforms with millions of users, healthcare systems, and market-leading real estate platforms.

What sets us apart: We operate as a collective of equals, not a traditional agency hierarchy. This means you work directly with senior specialists who own their craft - no account managers, no juniors learning on your budget. Each project gets the exact expertise it needs, whether that's healthcare compliance, high-performance streaming, or e-commerce at scale.

Our three core services

• App Maintenance & Updates - Keep your app current with platform requirements, security patches, and performance optimization
• Feature Development Extend existing apps with AI integrations, modern UI/UX, or new business capabilities
• End-to-End Development - From concept through App Store launch, including backend, infrastructure, and ongoing support

Technical Excellence

We master the full mobile stack: Kotlin, SwiftUI, React Native, Flutter, plus backend technologies like Node.js, Python, and cloud platforms (GCP, AWS). Our code follows Clean Architecture principles, comprehensive testing, and security-first approaches that pass enterprise audits.
