Skills / Tools in practice

A toolkit shaped by the work.

Commercial C++ engineering, Unity systems, operational web platforms and data-driven tools. Each capability connects to a project or a working environment.

Capability map

Seven branches.
Shared evidence.

Hover a branch to isolate it. Projects sit between the branches they prove: one system can be evidence for engineering, delivery and operations at once.

The full list

Every skill,
with its depth and its proof.

Core

I write and run this myself, day to day.

AI-assisted

I own requirements, design, review, integration and release; AI tooling writes most of the code.

Foundation

Studied or used before; quick to pick back up.

02

AI-native development

Core

Used in my development workflow every day; no autonomous agents run operational tasks in production.

Requirements, workflow modelling and production delivery with AI coding agents under my own review: I own the business rules, the tests and what ships.

  • Claude Code
  • Codex
  • MCP tooling
  • Prompt design
  • Code review
  • Build / lint / test gates
  • Documentation

03

Web & operational platforms

AI-assisted

Application code is AI-assisted; deployment and operations are core.

Operational web software from workflow and data modelling through review, integration and production support. I design, review and run it; AI tooling writes most of the application code.

  • ReactAI-assisted
  • TypeScriptAI-assisted
  • Node.js / ExpressAI-assisted
  • REST API designAI-assisted
  • SQL · SQLite / MySQL
  • Linux · PM2 · Nginx
  • Git / GitHub
  • FlaskFoundation

Evidence

04

Low-code & workflow automation

Core

Front-line tools built directly on hotel workflows: data modelled in Lists, screens in Power Apps, rules in Power Automate, revised in live use.

  • Power Apps
  • Power Automate
  • SharePoint / Microsoft Lists
  • Microsoft Forms
  • Microsoft 365

Evidence

05

IT systems & digital operations

Core

The only IT contact across three operating hotels: hardware, networks, hotel business systems, access and vendors, with documentation and training so fixes stick.

  • Meraki Wi-Fi & networking
  • Microsoft 365 administration
  • PMS · RMS Cloud
  • EFTPOS & payment reconciliation
  • Multi-site hardware support
  • Door-lock systems
  • Servers & UPS
  • Access & identity management
  • Vendor management
  • Documentation & training

Evidence

06

Data, mathematics & statistics

Core

Probability, statistics and data work grounded in a master’s with a Data Science major and in verified game mathematics.

  • Probability & statistics
  • Python / pandas
  • SQL
  • Monte Carlo simulation
  • RTP / slot mathematics
  • Excel
  • Machine-learning conceptsFoundation

Evidence

07

3D & visual design

Core

A smaller branch: the tools are core, motion and CAD are foundation.

An environmental-design degree and an ArtStation archive behind the eye for how interfaces and spaces feel.

  • 3DS Max
  • V-Ray
  • Photoshop
  • Premiere ProFoundation
  • AutoCADFoundation
  • SketchUpFoundation

Evidence

Working with AI

Faster iteration.
Deliberate ownership.

I use AI agents to assist implementation and iteration. I remain responsible for understanding the problem, choosing boundaries, reviewing code, debugging behaviour and accepting what goes into production. My deepest conventional coding experience is in commercial C++ game development.
