The Strategic Architect

Janoš Žibrat

I am a Senior Software Architect with 18 years of experience specializing in taking complex, large-scale systems and transforming them into modern, high-performance engines. My expertise is rooted in architecting robust, full-stack solutions with C#/.NET Core and modern JavaScript/TypeScript.

My professional life is defined by the strategic focus, precision, and elite discipline I cultivated as a former international ATP-ranked tennis player. This mindset ensures that every project I touch—from greenfield development to high-risk project rescue—is approached with dedication to long-term architectural integrity and quantified results.

Impact & Expertise

My expertise My focus is on delivering concrete, measurable improvements and ensuring your systems are ready for the future:

  • System Modernization: I specialize in Monolith-to-Microservices Migration, successfully leading complex projects that boost performance and scalability. For instance, I spearheaded a migration that resulted in a 35% performance boost.
  • Performance Engineering: Whether developing real-time industrial automation systems with sub-millisecond latency or transforming a legacy UI into a high-performance SPA, I drive efficiency. I’ve reduced load times by 40% through frontend architecture refinement.
  • Reliable Delivery: As a consultant, I am highly disciplined in project execution, maintaining an exceptional 99% on-time delivery rate and frequently stepping in to stabilize and refactor high-risk projects for clients.
  • Leadership & Mentoring: I ensure modern architectural standards (SOLID, DDD) and methodologies (Agile, TDD) are adopted, mentoring teams to build sustainable, scalable codebases.

Let’s Build Your Next System

Whether you need a full-stack system designed from the ground up, a technical leader to guide your team, or an expert to solve your most pressing architectural challenges, my goal is the same: to deliver exceptional results with unwavering discipline.
