HOW I WORK

  • ARCHITECTURE

    I design back-end systems that stay transparent, scale safely, and remain straightforward to extend years down the line.

  • SYSTEM INTEGRATION

    I connect APIs, services and business systems so that data flows securely, and processes run reliably and automatically.

  • AUTOMATION

    I build digital processes that connect systems together, cut down manual work and make day-to-day operation simpler.

  • EFFICIENCY

    Modern, AI-assisted tooling speeds up delivery, while I make no compromise on quality, security or long-term maintainability.

HOW I THINK

I don't build templates. I build digital systems that solve real business problems.

A LONG-TERM VIEW

Handover isn't the end of a project, it's the start of long-term operation.

TECHNOLOGY AND BUSINESS VALUE

Technology alone creates no value. It becomes valuable when it solves a real business problem.

How I think.

I've always been drawn to what happens beneath the surface. It wasn't the world of buttons, animations or colors that captured me, but how systems work together, how services communicate with each other, and how to build back-end systems that are fast, secure and reliable in the long run.

I learned the fundamentals of the craft in the Software Engineering program at the University of Szeged, where I gained a strong IT and engineering mindset. Later I complemented it with practical, project-based training at the Progmasters Coding Academy developer bootcamp, where I gained even more hands-on experience through real development projects.

In recent years I've worked as a Senior Backend developer, and I still design and develop back-end systems full-time. I specialize primarily in Java technologies and the Google Cloud Apigee platform, and I also have several years of professional experience in AWS environments.

In 2025 I started my own business, because I wanted to make this mindset accessible to small and medium-sized companies too.

Honestly, front-end development was never really close to my heart. Not because I don't consider it important – quite the opposite. A well-designed user interface is a key part of every digital product. I've simply always been more motivated by what happens behind the scenes: architecture, business logic, APIs, data handling and integrations.

Artificial intelligence, however, has changed modern development enormously. Today there are tools that let you quickly create modern, clean and professional user interfaces. This makes it possible for projects to be visually high-quality too, while I can put most of my energy into what I deliver the most value in: designing stable, secure and scalable back-end systems.

I believe that in today's rapidly changing technological environment it's not enough to know a single programming language or framework. To create truly future-proof digital solutions, you need system-level thinking. You have to understand architecture, performance, security, integrations – and how technology decisions affect the way a business runs.

This mindset defines my work too. I don't simply build websites or applications. I build digital systems that automate, simplify processes, reduce manual work, and create real business value.

For me, a project doesn't end at handover. My goal is to deliver solutions that still run reliably months or even years later, are easy to extend, and can grow together with the business.

I believe technology alone isn't valuable. Value comes when you apply the right technology to the right problem. That's exactly why I don't build templates, but digital systems that solve real business problems.
