Review a migration, diagnose failed refreshes or plan a lakehouse and its reporting layer.
Microsoft Fabric →Eyüp Türkay · Software engineer · Istanbul & Bratislava
Data platforms, reporting and business automation.
I build Microsoft Fabric data platforms, Power BI reports, n8n workflows and custom software. I also repair and maintain existing systems. Based in Istanbul and Bratislava, working with businesses across Europe in English and Turkish.
How I can help
Power BI
Define measures, build semantic models and fix inconsistent figures or slow reports.
Power BI →n8n and integrations
Connect business systems, automate a task or repair a workflow that is failing.
n8n and integrations →AI project recovery
Started a Claude or AI project, but now it is stuck?
I help business owners make sense of unfinished AI-built software and automations: review what exists, identify what is failing, and agree a practical recovery plan before more time is spent.
- Review the code, workflows and integrations
- Find reliability, security and handover gaps
- Repair or simplify the parts that matter
Reporting & dashboards for logistics companies
Don't wait for the analyst hire. Your first dashboard can be live in two weeks, at a fixed price.
Your TMS, ERP, telematics and spreadsheets already hold the answers. I review the data you have, decide with you which reports matter, and turn them into dashboards your managers actually open.
- Works on your existing software. Nothing to replace.
- Read-only access or exported files. Your live systems stay untouched.
- Weekly summaries with plain-language commentary and alerts can follow, on figures we have agreed.

Working together
What happens after I send an enquiry?
I reply within one business day. We discuss the problem and the systems involved, then agree the scope, deliverables and price before development starts.
Where do you work?
I work from Istanbul and Bratislava, remotely with clients across Europe. My business is registered in Slovakia. I work in English and Turkish.
Can you work on an existing system?
Yes. I first review the application or workflows and their known issues, then agree the repairs or maintenance needed.
Tell me what you need help with.
A short description of the problem and the systems involved is enough to start.
