More about my backgroundUpdates
Professional changes, new projects and personal milestones – selected developments that are shaping my journey and allowing this website to grow over time.
What started as the idea of a digital professional profile has become my first personal website. It combines my professional background with selected practical projects, my way of working and my voluntary engagement – complemented by a more personal look at some of my interests beyond work. The website is not intended to be a finished project. It will continue to evolve alongside my professional journey, with new experiences, projects and developments.
With the contract signed, my next professional step is confirmed: on 1 October 2026, I will join Netto Marken-Discount as a Verkaufsleiter (Retail Area Manager). This new role will expand my previous focus on processes, analysis and operational support with significantly greater responsibility for leadership, store performance and results.
In preparation for my new professional environment, I explored workforce scheduling in grocery retail in depth. Over several development stages, this resulted in my own Excel/VBA-based AutoPlanner – covering staffing demand, peak-period logic and automated weekly scheduling.
View projectFollowing my previous work as an examiner for the IHK for Munich and Upper Bavaria, I have resumed my voluntary engagement in Germany's vocational examination system. Since 2026, I have served as a volunteer examiner for IHK Halle-Dessau, focusing on the retail qualifications Verkäufer/-in and Kaufmann/-frau im Einzelhandel.
After around 19 years in retail and a wide range of roles and responsibilities, a period of professional transition begins. My experience across store operations, logistics, IT & organisation and sales support provides the foundation for my next step.
Projects & Results
Many of my projects grew out of concrete challenges in day-to-day retail operations. Rather than simply describing problems, I used data, processes, and hands-on experience to develop practical solutions.

A weekly report containing up to around 100,000 data rows was transformed through a custom Excel solution into targeted, practical working lists.

Three separate reports from the merchandise management system were automatically consolidated, cleaned, and transformed into a central working basis for inventory analysis.

A dedicated analysis made pre-counts, inventory levels, and potential differences transparent, helping identify anomalies before the final inventory result.

Analysing KPIs, understanding root causes and turning the findings into concrete fields of action for day-to-day operations.

A dynamic evaluation model combines shrinkage, sales and store area to make different stores comparable through an automated ranking methodology.
A privately developed Excel/VBA learning project from 2026: an automatic staff scheduler for a fictitious food retail store. Not an employer project and not a company system used in production.
View personal projectWhether it is an analysis tool, an inventory process or new reporting, my approach usually starts with the same question: where does the real cause lie? Data provides the basis for that. What matters to me, though, is developing a solution that is understandable, workable and lastingly useful in everyday operations.
