At Mauve Mailorder Software GmbH & Co. KG, I worked on System3, a long-running ERP and e-commerce platform for German pharmacies. I extended its payment configuration end to end, contributed to the WinForms-to-WPF/MVVM migration, and built automated UI tests with a CI pipeline.

On freelance projects, I architected a multi-tenant biometric attendance SaaS and led the engineering team for Mutabbib, a healthcare platform. I also delivered .NET APIs and Angular features for government and institutional systems at egabi Solutions.
