Description

Mobile & Full-Stack Engineer | Android, Flutter, Web & AI | Building scalable digital products from idea to launch

I help startups and businesses build scalable mobile apps, web platforms, and AI-powered systems that are fast, reliable, and ready for production.

If you’re looking to develop an Android/iOS app, a Flutter cross-platform product, a web dashboard, or an AI-driven automation system, I can take your idea from concept to fully deployed product with clean architecture and long-term scalability in mind.

I specialize in building production-grade applications that don’t just work but scale. From MVP development to enterprise systems, I focus on performance, maintainability, and real-world usability.

What makes me different is my ability to work across the full stack mobile, web, backend, and AI allowing me to deliver complete end-to-end solutions instead of fragmented development. This includes everything from system design and API development to UI implementation and deployment pipelines.

I’ve delivered 120+ projects across freelance platforms and contributed to applications with over 1M+ downloads. My experience also includes working on enterprise systems used in large retail environments such as Lidl and Aldi through GK Software SE, as well as building independent products like SaaS platforms and AI-integrated mobile apps.

Typical projects I handle include:

Mobile apps (Android, iOS, Flutter)

SaaS platforms and MVPs for startups

Web applications and admin dashboards

AI-powered automation and smart workflows

Backend systems, APIs, and scalable architectures

Currently, I run a Berlin-based Software Company focused on building modern web, mobile, AI, and interactive digital products for startups and growing businesses.

I enjoy working on long-term products where I can contribute not just as a developer, but also in shaping architecture, technical direction, and product scalability.
