Solution ArchitectERP & System IntegrationMicrosoft Platform
Freelance, based near Hamburg, remote and on site
I build data and integration solutions that run reliably — and land with the teams who use them. I design the architecture, build it myself and bring people along.
My path began in a trade.
As an electronics technician I learned to take things apart, understand them and put them back together so they work reliably. That mix of practice, structure and technical understanding is what I bring to digital work as a Solution Architect today.
As a freelancer I support companies in introducing and evolving central systems: Business Central, CRM, integrations, data migrations, automation and AI agents.
I work where business teams, IT and partners meet, translate requirements into workable architectures, and use enablement to make sure solutions land with the team.
