What I'm looking for

I’m available for remote, full-time, contract, or freelance work.

At a private technology company, I develop Android and iOS apps with Flutter and build .NET APIs for business operations. I connect mobile products to backend APIs and external services, and publish and maintain apps on Google Play Store and App Store.

I’ve brought GitHub Copilot, Claude, and Cursor into the development workflow and designed agentic workflows for code generation, automated tests, and incident resolution. I also optimize SQL Server queries and business logic to improve response times in critical processes.

At SIGEL, I developed web applications and backend services while contributing to technical training programs for young people in coordination with Swisscontact. Earlier, at SOTECSA Software & Technology, I integrated electronic invoicing into existing billing systems and developed software solutions for enterprise clients.
