🌍 About Me

"In an era of accelerated AI, adaptability drives innovation."

I am a systems thinker who architects and engineers intelligent systems, inspired by the principles of nature and cognition. My approach is rooted in a deep academic foundation of the most successful systems to ever exist: those found in biology, and the human mind. I leverage first principles from these domains to engineer AI & ML systems and software that is not only powerful, but also robust, intuitive, and meaningful.

This is not just a job or a career for me; it is the practical application of a lifelong curiosity, and years of formal academic studies, into the nature of: life & biological systems, complex systems, philosophy, psychology, cognition & learning, languages & linguistics, programming & software development, data science, artificial intelligence & machine learning.

As we enter the era of agentic AI & physical AI (robotics), my mission is to move beyond simply studying, developing my own projects, or building tools, and begin orchestrating intelligent workforces in companies and institutions, with likeminded individuals. I am driven to architect and govern these powerful new systems responsibly and am looking for a team that shares this vision.
