Throughout my career, I have designed and developed scalable software solutions using technologies such as C++, C#, Java, Python, .NET, SQL, and Unity. My experience spans backend development, full-stack applications, system architecture, database design, real-time rendering, and AI/ML-driven solutions. I enjoy solving complex technical challenges and building robust systems that combine performance, maintainability, and business value.
Most recently, I served as Chief Technology Officer (CTO), where I was responsible for technology strategy, software architecture, product development, and leading engineering teams. This role strengthened my ability to bridge the gap between business objectives and technical execution, ensuring that products are both technically sound and aligned with organizational goals.
One of the highlights of my career has been the development of advanced visualization and simulation platforms. I was responsible for the complete software architecture and implementation of the jDome BikeAround system, developing the entire software platform in C++ and OpenGL, including real-time graphics, hardware integration, and system design from concept to finished product.
I have also developed numerous VR, AR, and mixed reality applications using Unity, ranging from interactive product visualizations and training simulators to immersive educational experiences. These projects have involved creating engaging and technically sophisticated solutions for both desktop and mobile platforms, as well as modern VR hardware.
My experience covers the entire software development lifecycle - from requirements analysis and architecture to implementation, testing, deployment, and long-term maintenance. I thrive in environments where I can combine technical expertise, product thinking, and strategic leadership to create innovative solutions and deliver meaningful results.
