Simulation & AI Engineer

I build systems that
model reality.

From constraint solvers, digital twins to LLM-powered agents — I turn complex, messy real-world problems into production software for defence, energy, and finance.

SimAgent

Describe what you want to simulate in plain English. An LLM agent configures and runs the simulation, then visualises the results.

About

I'm Samuel — a Senior Simulation & AI Engineer at Deloitte. I embed directly with client teams in defence, energy, and financial services, scope their hardest problems, and ship full-stack production systems.

My background is uncommon: I've spent years building agent-based models, discrete event simulations, and constraint solvers — systems that model complex real-world behaviour. Now I'm applying that same thinking to LLM-powered agents and AI applications.

I studied Physics at Durham and Artificial Intelligence at King's College London. I hold SC security clearance and have delivered systems that inform multi-billion pound decisions.
