What I'm looking for

I'm looking to build scalable SaaS, real-time, cloud, and AI-enabled products where I can own architecture through production operations and deliver measurable performance, security, and user-experience improvements.

I've built and scaled software products at Spotium GmbH, XM, Motive, and StrategicSystemsInternational, spanning SaaS platforms, trading interfaces, fleet-management features, and enterprise tools. At Spotium, I delivered a greenfield Angular, NestJS, MongoDB, Redis, and Azure platform end to end, reducing average API response time from about one second to 200 ms while supporting 50 requests per second.

I've developed real-time Angular interfaces used by thousands of active users, integrated REST APIs and WebSocket streams, and shipped Dispatch features with .NET Core and C#. I focus on secure, maintainable production systems through CI/CD, caching, observability, RBAC, JWT authentication, and AI-powered product features with prompt guardrails.
