About
I like taking things apart to see how they actually work — code, curriculum, brand systems, it doesn't matter. Understand the system, then build it better. That's the whole job description, really.
Right now that means designing Australian Curriculum-aligned coding programs at EdTech Group — Minecraft block-coding through to Python, JavaScript, and full web dev, across a live portfolio of 48–50 concurrent projects. That work extends to writing curriculum for corporate partners like IBM, Lenovo, Shell Energy, and Microsoft — translating their briefs into something a classroom can actually run with, not just a nice PDF. Before that, it meant general WordPress maintenance and design work, keeping sites running and looking right.
I'm in my third year of a Bachelor of Cybersecurity, and what draws me in is cause and effect — how systems actually fail, not just how to patch them after. Right now that means building a network intrusion detection model on a Raspberry Pi, trained on the UNSW-NB15 dataset using a neural network, K-means clustering, and transfer learning — turning the theory of how an attack happens into something that actually catches one.
Experience
Applied Cybersecurity
In ProgressThird-year Bachelor of Cybersecurity student, focused on how systems actually fail — the cause and effect behind an intrusion, not just the patch.
Current project: a network intrusion detection model on a Raspberry Pi, trained on the UNSW-NB15 dataset using a neural network, K-means clustering, and transfer learning.
Front-End Development
7 yearsI build responsive, user-centric sites in HTML, CSS, and JavaScript — clean, fast, and actually usable by the people who land on them, not just nice to look at. That includes everything from client sites to the animation experiments and cyber-education tools in my Selected Work below.
Graphic Design
8 yearsI design for clarity first — clean, brand-aligned visuals in Adobe Creative Suite, Canva, and Figma that communicate before they decorate. From slide decks to full brand systems, the goal's always the same: make it look effortless, even when it wasn't.
Tutor
2 yearsI run hands-on workshops in Robotics, Block Coding, Python, C++, HTML/CSS, JavaScript, App Prototyping, and Maths, meeting students at whatever level they're at. They leave having built something real — an app, a robot, a working script — not just followed along.
Curriculum Creative
1 yearI design and rebuild curriculum across a national program — 48–50 concurrent projects, delivered in 5 states to students aged 5–18. That includes core programs like Minecraft Education, Python, and JavaScript, plus corporate curriculum for IBM, Lenovo, Shell Energy, and Microsoft, along with the tracking systems and Educator Guides the team now runs on.
