About Me

A little bit about my background, skills, and journey as a developer.

My Journey

For over 15 years, I've been passionate about crafting exceptional digital experiences. My journey began with building simple PHP-based applications and hosting them on VPS servers, learning the fundamentals of web development from the ground up.

From those early days of managing servers and writing server-side code, I've evolved into building complex, full-stack applications using modern technologies. Today, I work with a diverse range of clients — from startups to established enterprises — helping them solve real business challenges through technology.

I specialize in modern web technologies, with a strong focus on security, user experience, reliability, performance and scalability. Whether it's architecting a robust backend, creating an intuitive frontend, or optimizing an existing application, I bring a commitment to quality and a problem-solving mindset to every project.
