Chief Technology Officer (CTO)
Information technology is my passion and my life’s work.
My training as an IT technician began with the fundamentals of digital signal processing and network technologies. Early on, I learned binary operations and programming at the hardware level.
Over the years, I have contributed to numerous projects — from developing modern websites to building more complex system solutions. I have always kept up with the latest technologies, diving into new programming languages and SDKs to apply them effectively. Thanks to high-level languages and frameworks, programming has become far more efficient today.
Project management methods such as Scrum and Trello support me in planning and coordinating tasks, while version control tools ensure seamless collaboration within a team.
Yet before writing the first line of code, it is crucial to answer some key questions: How will the software be deployed? What strategies will be used for backup and scaling? Which database model, programming language, and framework are most suitable?
Solid technical knowledge helps guide these decisions, but nothing can replace real-world experience. That is why I will never stop experimenting, exploring new technologies, and continuously learning.
