Background

I came to systems engineering from physics. That background is the reason I work the way I do: I want the structure to be legible, and I would rather implement something from scratch than trust a black box I do not understand.

Most of my time now goes into an independent research programme on liquidation cascades in leveraged crypto markets — two first-author preprints in 2026 — and into the software that measures them, because in this line the pipeline is the result. The rest sits at the intersection of cryptography and adversarial infrastructure: protocol-level tools in Rust, security research that involves reverse engineering things to see how they actually work, and cryptography studied by implementing it — SIS lattices, the number-theoretic transform, a Baby-Ligero prover.

Recently I presented a paper on a real-world Web3 supply-chain attack at the iSCSi 2026 conference, accepted for publication in an Elsevier journal — more on the research page.

Currently

  • Independent research program

    Critical phenomena in leveraged crypto markets — do liquidation cascades announce themselves, and in which state variable? Two preprints on arXiv (q-fin.ST / physics.soc-ph) — Part I found no univariate early-warning signal that survives across events and is under review at Physica A; Part II measures the order of the transition and the branching ratio of the engine itself. Alongside them, a private Rust workspace runs cross-venue strategies live — the same markets, from the other side. See research.

  • Web3 security research

    A supply-chain attack case study accepted at iSCSi 2026, an ongoing audit practice, and a first bounty submission under review — the write-up follows disclosure.

  • Execution engineering

    A cross-venue perpetuals workspace in Rust, written up in full — including the parts that lost money — and, on Solana, an atomic multihop executor in Anchor (CPI adapters, LiteSVM-tested). See work.

  • Foundations

    Cryptography from scratch in Rust — lattice-based primitives and IOP-style proof systems — plus dag_exec (a std-only sync DAG executor) and ultrafold-micro, which uses it to ask where parallelism actually pays inside a proof pipeline. The answer so far is a measured negative, which is still an answer.

  • Open to work

    Looking for research-engineer, scientific-software or HPC work in a research group, and open to freelance and research engagements. See contact.

Research interests

Complex systems and econophysics — phase transitions, cascades and early-warning signals in systems that are leveraged, coupled and adversarial — alongside applied cryptography and proof systems. The common thread is structure emerging from simple rules, and the discipline of getting from a clean idea to a measurement that could have come out the other way.
