About Me.

Driven by innovation, problem-solving, and user experience, I strive to create high-quality digital solutions with a lasting impact.

From engineering to code: a passion for solving complex problems.

With a background in civil engineering and project management, my journey into web development was born from a desire to build concrete and meaningful solutions. After completing my studies in Belgium and the United States, I dove into the world of code, perfecting my skills through practical experience and constant technological monitoring.

Today, as a Full Stack developer, I specialize in creating well-structured, high-performance applications that offer a seamless user experience. Whether designing intuitive frontend interfaces or developing scalable backend architectures, I focus on quality, efficiency, and continuous improvement.

Outside of coding, I enjoy sports and adventure. From mountain hiking to basketball, traveling, and exploring new places, I love discovering new things and staying active.
