Freelancer profile translated to English.

Description

As a Full-Stack Developer and Product Manager, I combine technical implementation strength with product understanding.

This means for clients:

no overhead from coordination loops between development and product.

Both from a single source.

My projects range from Keycloak SPI implementation for an IoT product to planning and managing native mobile app development, to independently implementing a complete web and mobile platform, from architecture to deployment.

I work remotely and am focused on structured, asynchronous collaboration.

Decisions are documented, progress is communicated without micromanagement.

I am particularly suitable for projects with requirements for technical depth combined with product complexity:

iIoT & Mobility

Auth Infrastructure

Mobile Apps or scalable web platforms.

Industry field of expertise

Languages

German
Native or bilingual
