Work

Delivered core mobile-commerce journeys end to end across German and Austrian markets, from customer state and cart logic to checkout, CMS, and loyalty flows.

Shipped a production event platform where organizers could publish ticket shops, track sales, and run entry from the same system across web and mobile.

Replaced 30-second refreshes with live telemetry and explicit stale-state handling, so operators could act on the dashboard instead of walking to the machine.

Replaced manual spreadsheet analysis with reproducible pipelines and audit-ready reports that clinicians could regenerate and defend later.

Gave the product a data model that could represent partnered users, group consent, and matching rules without piling on special cases.

Kept late-wave simulation smooth by removing GC churn and bounding the work inside the hottest update paths.
