About Me

Three decades of passion-driven development, from desktop applications to cutting-edge mobile experiences.

My Journey

My career began in the early 1990s when personal computers were becoming mainstream. Over three decades, I've witnessed and participated in the evolution of technology—from desktop applications to the mobile revolution.

What started as curiosity about programming evolved into a passion for creating mobile experiences. I've been developing for iOS since the App Store launch in 2008, and have expanded to Android and cross-platform development.

Today, I focus on building practical, user-centered mobile applications. My experience spans from utility apps to complex enterprise solutions, always emphasizing clean code and reliable performance.
