Professional Journey

With over two decades in software development, I've evolved from a passionate programmer to a seasoned tech leader and mentor. My journey began in the late 90s, working with early web technologies and witnessing the transformation of the digital landscape firsthand.

Throughout my career, I've led development teams at startups and enterprises, architected mission-critical systems, and helped countless developers advance their careers. My experience spans from building high-performance web applications to implementing cutting-edge AI solutions.

I pride myself in not just being a "coder" but understanding the importance of efficiency and revenue generation. I can work fluently in photoshop, illustrator, animator, blender, and many other creative tools and apps.

I can code web, desktop, systems, ai models, and more. I am far more than a full stack developer or a one trick pony. I am like a guided missile, point me at your biggest problem and I will find clever ways of solving it.
