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.

Made machine and sensor information accessible through a production interface used for operational monitoring, while improving the maintainability of the supporting software and operational workflows.

Helped make clinical imaging information searchable and usable through a maintained product while supporting controlled data access and audit-ready reporting.

Turned six separate app ideas into one codebase where authentication, theming, and configuration are solved once, the second product shipped without rewriting the first product's foundation.

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 free-text care notes with a typed, multilingual record where every logged event carries a category, a severity, and an author, so a handover between a family member and an agency carer no longer loses information.

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.
