Engineering Impact, Building the Future
I’m Janoš Žibrat, a Senior Software Developer with a deep-seated passion for architecting and delivering high-quality, scalable enterprise solutions. For over a decade, I’ve specialized in driving the full software development lifecycle—from Domain-Driven Design (DDD) and architectural strategy to reliable, containerized deployment using Docker and message queueing systems like RabbitMQ and Apache Kafka.
My Technical Focus: Full-Stack Excellence
My expertise is rooted in the .NET Ecosystem and modern JavaScript frontends, allowing me to deliver true full-stack excellence:
- Backend & Architecture: I excel at developing robust backend systems using C#/.NET Core, focusing on highly available Microservices and effective data handling with Entity Framework (EF) Core and Dapper. I prioritize DDD and Test-Driven Development (TDD) to ensure code is maintainable, reliable, and built to last.
- Frontend Modernization: I spearhead UI initiatives, transitioning applications to high-performance Single-Page Applications (SPAs) using modern frameworks like Vue.js, React, and Angular, all powered by TypeScript for stability and superior user experience.
- DevOps & Scalability: I manage end-to-end development pipelines, implementing Docker for consistent environments and leveraging synchronous processing with RabbitMQ/Kafka to achieve superior scalability across client systems.
Key Professional Achievements
My career has been defined by leading strategic modernization efforts and delivering measurable performance improvements:
- Driving Performance: I successfully architected and led a strategic modernization from a legacy C# monolith to a .NET Core Microservices architecture, resulting in a 35% performance enhancement.
- Enhancing Efficiency: By integrating DDD and TDD practices, I significantly improved code maintainability and reduced deployment errors by 25%.
- Mentorship & Quality: As a technical lead, I guided design decisions, mentored junior developers , and implemented integrated automated testing pipelines that accelerated deployment frequency by over 50%.
The X-Factor: Discipline Forged in Sport
What truly sets my approach apart is the discipline and strategic focus cultivated through my past as a former nationally ranked competitive athlete. As a Multi-National Tennis Champion and ATP-ranked professional, I developed a unique ability to maintain elite discipline, show resilience under pressure, and possess superior time management skills—traits that directly translate to successfully tackling complex software engineering challenges and delivering projects with a near-perfect 99% on-time rate.
I bring this same commitment to peak performance to every line of code I write and every system I architect.
