Professional Background

Backend engineer focused on transforming enterprise systems through strategic refactoring and clean architecture.

I’ve worked on maintaining and extending LiveAgent, a large-scale web application used by over a million users worldwide. My primary focus was on improving architecture, refactoring legacy modules, and ensuring long-term maintainability.

In addition to product work, I’ve completed several freelance projects — including internal tools and systems for a local camera security company, website maintenance for basketball club BBA Komárno, and backend work for a private transport company in Komárno.

Active Stack

  • Backend: PHP, .NET (C#)
  • Frontend: JavaScript, Razor, HTML, CSS
  • GameDev: Unity 2D
  • Persistence:
    • Relational: MySQL, MSSQL, PostgreSQL (OLAP), SQLite
    • NoSQL: ElasticSearch

I’ve worked with a broader range of technologies — this list reflects only what I currently use actively.

Personal Traits

My strongest experience is in web development, mainly with PHP and C#. But these are simply tools — I consider them a means of applying sound software engineering practices. I'm committed to continuous learning and to delivering scalable, maintainable, and testable software, whether building new systems or refactoring legacy codebases.

Software Engineering Principles

I design and implement software guided by proven principles and methodologies that ensure long-term maintainability, scalability, and clarity of the codebase. My work consistently follows:

  • Domain-Driven Design (DDD): Structuring code around the business domain, using bounded contexts, aggregates, and clear separation of concerns.
  • SOLID Principles: Writing modular, testable, and maintainable code that follows object-oriented best practices.
  • DRY (Don't Repeat Yourself): Eliminating duplication by extracting reusable components and logic.
  • Clean & Maintainable Architecture: Prioritizing clarity and long-term sustainability over quick fixes.

Most of my professional work involves refactoring and extending legacy systems, applying these principles to gradually improve architecture and deliver higher-quality software.
