Vaadin freelancer in Berlin

I am an independent Vaadin developer based in Berlin, trading as infraLeap. I build and migrate Vaadin Flow applications with Java and Spring, in English or German.

What I take on

• I build Vaadin Flow applications on Spring Boot with Spring Data, Spring Security and REST, and with Hilla where a JavaScript front end is wanted.
• I migrate Framework 6/7/8 applications onto Flow 25 while they stay in production.
• I build retrieval-augmented AI assistants into Vaadin applications.
• I step in where a project has stalled: single sign-on, real-time collaboration, threading, session leaks or accessibility.

Background

• I have worked with Vaadin since 2014, for end customers in automotive, medical devices, finance and crypto, public administration and pharma.
• For most of that time I was one of Vaadin's most experienced migration engineers, and I set up and ran its Berlin office.
• I am a Vaadin Certified Developer and a Diplom-Informatiker (M.Sc., Computer Science) from Freie Universität Berlin.

Working with me

• I contract through infraLeap, under my published terms of business.
• I carry IT liability insurance, confirmed by exali.
• I lead teams of up to 15 engineers, join yours as a team member, or come in as the one specialist.
