For most teams that reach out to me, the problem isn't a lack of tool budget. It's tools that don't talk to each other – and a person who manually reconciles this daily.
I make these systems work. Not as a consultant who delivers a plan and disappears. Not as a developer who needs a perfect brief. I dive into the problem, define the scope myself, and build what actually runs afterward – tested, documented, maintained.
What this means in practice:
I connect systems that don't natively speak to each other – that's system integration in its true sense. I transform manual handoffs into workflow automation that runs on its own and doesn't let anything slip through the cracks. CRM logic, lead lifecycle processes, back-office routines.
Tool landscape: n8n, Make, Zapier, ActiveCampaign, Pipedrive, Affinity, Attio, HubSpot, and many more. API and coding skills where necessary. AI only where it truly adds value.
I'm not a specialist in one tool, but in the problem behind it. Tools change. The pattern usually stays the same: handoffs break, people compensate, systems grow uncontrollably. That's why I quickly get up to speed in new stacks and why the hourly rate doesn't grow with the tool list, but with what I achieve with it.
Fits if:
– your team is small and under operational pressure
– you have many tools, but too much manual work in between
– you're looking for someone who understands the problem before proposing a solution

Automatic Inbox RetrievalREAL ESTATEMay 2026 - June 2026 (1 month)Hamburg, GermanyFor a property management client, I developed a fully automated solution that retrieves new documents daily from the Deutsche Post E-POSTSCAN portal (dp-ds.de) and transfers them directly into the Immoware24 document management system.The workflow runs daily at 11 PM on a self-hosted n8n server and connects three systems: Deutsche Post's SFTP portal, Immoware24's WebDAV endpoint, and Microsoft Outlook for notifications.Technically, the SFTP structure of the portal was interesting: the documents are not directly in the root directory but in date-based subfolders (e.g., /20260608/), which required a two-stage directory query. The workflow first lists all date folders, filters for today's deliveries, and then processes the PDFs contained in each folder — XML files are automatically ignored.Each PDF file is saved with its original filename in the Immoware24 document inbox. In the evening, the client receives a structured summary via email: how many documents were transferred, their filenames, and if any errors occurred. In case of SFTP connection errors, a prioritized error email is sent immediately to allow for manual intervention.The project exemplifies how classic manual office processes — daily downloading and filing of mail — can be fully automated without the client having to switch their familiar system (Immoware24). - 7FridaysHead of Marketing & E-CommerceTRAVEL AND TOURISMFebruary 2024 - July 2025 (1 year and 5 months)Hamburg, Germany
