About Me
The person behind the projects.
Hi, I'm Marc, a web developer passionate about technology and the process of building products that are both useful and well crafted. I enjoy learning continuously, refining my skills, and challenging myself with new tools, ideas, and real-world problems.
I strongly value teamwork and collaboration. Working with people who share the same passion for technology pushes every project further, and I believe the best products are built through good communication, shared ideas, and a genuine commitment to improvement.
Outside of development, sport plays an important role in my life. I train at the gym from Monday to Friday, combining weight training and cardio. On weekends, whenever I have the chance, I go hiking with friends, explore mountain routes, and enjoy nature. That connection with outdoor activities was one of the ideas that inspired me to create DeltaRoutes.
I also like spending time playing guitar with my father. I am still a beginner, but it helps me disconnect from daily routines, stay creative, and maintain a healthy balance between work and personal life.
