Biography

Software Architect & Goalkeeper Coach | Constraints-Led Methodology & Systems Design

I am a pragmatic problem solver operating at the intersection of software architecture and modern goalkeeper development. Whether re-architecting complex legacy systems or designing training environments, my philosophy is defined by a single objective: bridging the gap between isolated theory and high-fidelity reality.

As a Software Architect, I specialize in transforming complex infrastructure into scalable, modern solutions. My background includes a Master’s in Computer Science and extensive PhD coursework with a focus on old-school AI. I excel in balancing technical rigor with business reality, utilizing root cause analysis and performance engineering to drive zero-downtime migrations and significant cost optimizations.

As a Goalkeeper Coach (UEFA C, United Soccer Coaches Advanced National), I translate this systems-thinking approach to the pitch. I utilize a Constraints-Led Approach (CLA) and Representative Learning Design (RLD) to move goalkeepers away from isolated technical repetition and toward “repetition without repetition”. Mentored by former Manchester United GK Coach Eric Steele, my sessions prioritize perception-action coupling, ensuring that goalkeeping actions emerge naturally from tactical decision-making and live-play scenarios.
