software developer. I build, tinker and break systems to understand them better — from memory allocators to cloud pipelines.

four domains, one address space

Most of my work falls into four areas: systems, machine learning, cloud & security, and the web. I studied Systems & Architecture at ANU and taught there until early 2026.

Each area keeps one colour for the rest of the page. The scenes below are rendered live in WebGL and resampled to characters.

$ lsmod | grep sys

systems & architecture

Low-level C for allocators, OpenMP and CUDA for HPC — and I taught COMP2310 at ANU.

machine learning

Radiance fields and 3D Gaussian splatting at Trellis Data, plus a TensorFlow.js style-transfer pipeline.

cloud & security

Agentic LLM pipelines on AWS Bedrock, with Terraform and Ansible deploying cyber-simulation infrastructure.

Next.js + TypeScript here, Remix + Supabase at Ohna. Postgres for modelling, Flutter on mobile.

Garage

Hot Wheels collection scanned as 3D Gaussian Splats

An interactive web showcase of die-cast cars reconstructed as 3D Gaussian Splats and rendered in-browser with the PlayCanvas engine (WebGL2), streaming compressed SOG bundles with neighbour preload.

Built the full capture-to-asset pipeline: video frames → COLMAP pose estimation → monocular-depth background masking → MCMC-based 3DGS training via the open-source brush trainer.

Picasso

Neural style transfer that runs in the browser

A web demo of Google Magenta's arbitrary image stylization network (Ghiasi et al., 2017) — a feedforward style-transfer net converted to a TF.js GraphModel and run client-side on WebGL.

Moved inference out of Python entirely: the FastAPI backend is now a ~80 MB static file server with no TensorFlow, while the float16-quantized model (~30 MB) ships from /model/ and runs in the user's browser.

NeoAuth

Your password is a sequence of objects

Graphical authentication: pick an ordered sequence of 6–8 everyday objects, then sign in by spotting each one inside randomly composited challenge images. Nothing is typed, so nothing can be shoulder-surfed or keylogged.

Challenges are single-use and expire in minutes, and secrets are stored as peppered HMAC wrapped in Argon2id. Started as a COMP4500 research proposal — the live stack runs FastAPI + MariaDB behind a Cloudflare Tunnel with no inbound ports.
