About Me

With over 10 years of experience developing business-critical applications, I specialize in systems that remain maintainable and scalable. My focus is not just on code, but on sustainable product quality.

From award-winning research projects (Intel ISEF Finalist) to technical leadership at startups and enterprise projects with Domain-Driven Design – I bring solid experience from diverse contexts.

I prefer working with companies that think long-term: Architecture that scales beyond the MVP. Code that's still understandable two years from now. APIs that partners can integrate without surprises.

My commitment: To advise you as I would want to be advised – honestly, pragmatically, and focused on your business goals.

SaRaaS - Scheduling & Routing as a Service

Alpen-Adria University Klagenfurt

Build! founders program project: Developing customized optimization solutions for scheduling and routing problems.

As part of the Build! founders program at Alpen-Adria-Universität Klagenfurt, I co-founded a project developing a Scheduling and Routing as a Service platform. We designed foundational algorithms for scheduling and routing optimization problems with emphasis on performance efficiency. The platform delivers solutions within seconds of processing time, crucial for real-world applications.

AD-HOC WLAN Routing Protocol

Alpen-Adria University Klagenfurt

Award-winning research project: Development of a reliable multi-cast routing protocol on Layer 2 for robot swarms.

During my time at technical high school, I developed an AD-HOC WLAN routing protocol on Layer 2 in C++ as part of my thesis. The project was conducted at the Institute for Networked and Embedded Systems at Alpen-Adria University Klagenfurt. The goal was to implement a reliable multi-cast routing protocol for autonomous robots, enabling decentralized communication without central infrastructure.
