Software Engineer,
Physicist & Researcher
I operate at the boundary where theoretical physics meets systems engineering. Most of my work involves problems where the abstraction layers are leaking — where you need to understand both the mathematics and the metal to make progress.
Systems Engineering
Distributed systems, fault tolerance, and infrastructure where correctness is a hard constraint, not an aspiration.
Computational Physics
Quantum error correction, simulation methods, and the computational complexity of physical systems.
Research & Theory
Information theory, compiler correctness, and mathematical foundations of machine learning.
"I think about invariants before implementations and entropy before optimization. I write software the way I write proofs: with the failure modes stated up front."

Are you available for freelance or consulting work?
It depends on the project. I take on select consulting engagements in distributed systems, computational physics, and research-heavy engineering. Reach out via email and describe what you're working on.
What's your background — physics or engineering?
Both. I was trained in physics and drawn to engineering. The combination means I think about invariants before implementations. I approach software problems with a physicist's rigor and an engineer's pragmatism.
Do you collaborate on research?
Yes — particularly in quantum error correction, distributed systems theory, and the computational foundations of machine learning. If you're working on something in these areas, I'd like to hear about it.
What tools and languages do you prefer?
Depends on the problem. Python and Julia for research and prototyping. Rust and Go for systems work. TypeScript for web tooling. I don't have loyalty to tools — I have loyalty to correctness.
Can I use your writing or cite your work?
Published papers follow standard academic citation norms. Blog posts and technical writing on this site can be referenced with attribution. If in doubt, send me a message.
