PORTFOLIO

Selected software projects

These examples show how I approach real business workflows: understanding the rules, connecting existing systems and building the software needed to make the process work reliably.

The client descriptions are anonymous. Each project explains what I built and the rules behind it.

Custom business software

Multi-store inventory optimization

Multi-store retailer

A multi-store retailer needed stock, sales and incoming purchase orders brought together across stores and a warehouse. I built a private application that produces transfer and purchasing recommendations.

The calculations account for protected stock, incoming supply and lead times. Users review the recommendations and download Excel reports.

E-commerce integration

Supplier and e-commerce automation

Online retailer

An online retailer worked with suppliers using different files, protocols and APIs. I built integrations around the existing store to process stock and purchase costs, support selected supplier-order workflows and return shipment tracking.

Operators can preview stock changes, while tracking updates include deduplication and retry handling.

Reporting automation

Automated traffic-data reporting

Traffic-reporting professional

A traffic-reporting professional needed repeatable reports from raw measurement files. I built scripts that generate per-site Excel reports and a combined summary workbook.

The calculations include direction and vehicle-class counts, interval summaries and speed percentiles calculated from pooled observations rather than averages of daily percentiles.
