Freelancer profile translated to English.

Description

I am an integration engineer with a passion for helping companies build clean, stable, and future-proof APIs, ESB landscapes, and business processes. My focus is on API management, modern interface architecture, and the automation of complex workflows. I bring many years of experience with Java/Spring Boot, Camunda, and API gateways, ensuring systems communicate reliably. I modernize legacy systems pragmatically and without disrupting ongoing operations. Ultimately, my goal is always to build integrations that simply work and provide tangible relief to teams.
