As a programmer with 12 years of experience, my journey began at a young age, fueled by a fascination with computers and the joy of creating my own programs. Over the years, I've taken on various roles - from hands-on coding to decision-making, team leadership, and organizing business processes. My primary focus has been backend development, where I've built a strong foundation in Java and related technologies early in my career. In recent years, I've shifted my focus to .NET, where I continue to push my technical boundaries. Challenges don't intimidate me; in fact, I thrive on them. I've successfully tackled projects that others avoided, and I find great satisfaction in delivering results in tough situations. Outside of work, I'm a dedicated father of two daughters and an enthusiast of nature and dogs. While my gaming days have passed, I still enjoy a good movie when time allows.Java
