About
Over the past 25 years in software engineering and system architecture, I've had the privilege of building solutions across diverse industries, from early web applications and nationwide educational platforms to modern enterprise environments. Today, I focus heavily on full-stack development with Angular and .NET, helping organizations modernize legacy systems, scale high-traffic architectures, and build secure, user-focused digital products. Most recently, I've served as an Angular SME and Senior Full Stack Developer for Repower AG in Switzerland, leading frontend modernizations and engineering resilient C# backend services.
I enjoy digging into complex data workflows, refining UI/UX performance, and keeping continuous learning at the heart of what I do, which currently includes active exploration in AI multi-agent systems and agentic engineering.
For me, success is always about delivering reliable, scalable code that makes a real difference for the teams and end-users relying on it. I bring a self-directed, pragmatic mindset to every project, whether that means rescuing a complex system, mentoring developers through architectural shifts, or building a new product from the ground up.
