What I'm looking for

I'm looking to build secure, reliable software and cloud systems while continuing to explore AI, cybersecurity, and game-engine technologies. I value opportunities to mentor others, create useful technical learning content, and solve meaningful engineering problems.

I'm maintaining cloud storage and mission-critical cybersecurity software at itrust consulting for more than 30 companies, helping sustain 99.999% availability and customer data security.

I've supported legacy systems across VBA, Python, and Java, and built a Java data-translation API connecting an in-house web application with a government-certified application. I also help tutor trainees and onboard new hires.

Alongside engineering, I've written programming tutorials for Razeware, modernized learning content, and produced more than 100 hours of material on programming practices, design patterns, Unreal Engine, Unity, and Godot.

I've taught computer science, created self-learning materials that improved academic retention by over 20%, and completed a Ph.D. focused on virtual reality for professional training. I continue exploring AI, cloud infrastructure, cybersecurity, and game engines.
