Research & Focus Areas


Over the years, I’ve cultivated a research-driven approach to software engineering, where every project becomes an opportunity to push the boundaries of design, performance, and creativity. My work spans from enterprise-scale platforms to experimental game engines, always guided by the same principles: clarity, modularity, and adaptability.


Java & Enterprise Systems

My core expertise lies in designing and implementing modular, scalable software architectures using Java. This ranges from custom web frameworks and enterprise applications to backend systems built with proven design patterns and robust testing methodologies. I focus on creating systems that are not only efficient, but also maintainable and adaptable as requirements evolve.


Game Engine & Graphics Programming

Alongside enterprise work, I explore game engine and graphics programming, developing 2D/3D renderers and interactive systems in Java. Using frameworks like LWJGL, LibGDX, and JavaFX, I experiment with real-time rendering, physics, collision detection, and simulation. This work allows me to blend engineering precision with creative freedom — whether prototyping indie games or building reusable engines.


System Design & Reverse Engineering

I am deeply interested in understanding and restructuring complex software systems, with a focus on improving maintainability and adaptability. Much of this thinking is distilled in my book, The Zero Point Laws, where I explore principles of resilience and clarity in both legacy and modern Java codebases. I believe that well-designed systems should survive change without collapsing under their own weight.


Data-Driven & AI Systems

Finally, I apply Java to AI and data-driven applications, integrating APIs, databases, and real-time sensor data to create contextual, intelligent behavior. From predictive models to conversational agents, I focus on bridging practical engineering with intelligent system design, always ensuring reliability and performance.
