What I'm looking for

I'm seeking a role that combines engineering quality with real impact on production systems, where I can build reliable backend and web applications.

I've built a complete multi-tenant SaaS platform at Mercedes Silver Star, integrating Microsoft Dynamics 365 Business Central ERP through GraphQL.

For my final-year thesis, I designed a metadata-driven engine that applies to any entity, replacing the need for dedicated controllers and services. I also implemented binary permissions and multi-account supervision for secure ERP account management.

During an earlier internship at Mercedes Silver Star, I rebuilt Vue.js interfaces, fixed bugs, and introduced Caffeine caching to reduce ERP load and improve response times. I identified the static architecture limitations that informed the platform redesign.

I've also developed an event management platform with Express.js and React.js, a blockchain-based medical consultation mobile app, a collaborative blog, and a 2D card game. I'm looking to bring engineering quality and practical impact to production systems.
