Summary

Civil engineer working on the numerical side of geotechnical engineering, and the author of the software he uses. Current MSc research covers offshore wind turbine foundations — floating foundation concepts, anchoring and mooring systems, and structural health monitoring for far-offshore installations — alongside the finite element methods and constitutive models that underpin them. Author of KATAI 2D, a verification-driven finite element platform for two-dimensional geotechnical analysis written in C++, and of Nerve, a zero-dependency machine learning library in ANSI C. Also writes low-level C for software rendering and audio synthesis, released as an open-source demoscene engine. Developing engineering software on contract since 2016.

Research

  • Offshore wind turbine foundations: floating concepts, anchoring and mooring systems
  • Structural health monitoring for far-offshore installations
  • Constitutive modelling of soils, and the numerical treatment of yield-surface singularities
  • Verification methodology for engineering software
  • Coupled consolidation and groundwater flow
  • Deterministic, high-performance numerical code in C and C++

Projects

KATAI 2D

Apache-2.0

Sole author and maintainer · C++, Python, Finite element method

Open-source finite element engine for two-dimensional geotechnical analysis, where every capability is pinned to a published benchmark or a closed form.

Nerve

Apache-2.0

Sole author · C, WebAssembly, TypeScript

A single-header ANSI C library that runs transformer inference, sentence embeddings and on-device learning with no external dependencies at all.

Demos from nothing but C

MIT

Sole author · C11, Software rendering, Audio synthesis, Win32 threads

A dependency-free C11 renderer and synthesiser: every pixel and every audio sample in three finished demos is computed at runtime, on the CPU, from code
