Academic Direction
My interests sit around mathematics, applied problem-solving and decision-making, with possible future routes including maths, actuarial science, finance, technology and engineering.
Mathematical Problem-Solving
Maths is my strongest academic area, especially problems that require strategy, modelling and deeper thinking rather than simply applying a memorised method.
Applied Coding Example
Built a Python program in Year 10 to search for the best possible solution to a “Government Game” optimisation challenge set by a teacher.

Court Marshal, Party Host and General Assistant
Customer-facing role combining safety supervision, rule enforcement, party organisation and communication with families.
As a Court Marshal, I supervise activity areas, enforce safety rules and help maintain a controlled environment for customers. As a Party Host, I organise customer parties by checking guests in, showing them to their room, coordinating food, engaging with children and handling allergy forms.

Custom performance, setup and progression.
Riding Style
Focused on jumps, control, confidence in the air and building a bike that feels playful but capable.
Progression with Sam
Riding with Sam has helped turn hesitation into commitment. The “if you do it, I’ll do it” mindset has pushed confidence on features where commitment matters.
Having someone there to push with makes progression more fun and gives both riders the confidence to try features they might avoid alone.
Upgrade Philosophy
I upgrade parts based on how the bike feels, what improves confidence, and what suits the riding I actually do.

Gym
Progression, control and consistency.
Weighted strength
+80kgWeighted Dip
Dips have been a consistent movement throughout my training, building pressing strength, control and weighted bodyweight progression.
New focus
160kgDeadlift
Recently started deadlifting and reached 160kg early on, with the goal of progressing towards 200kg through consistent, controlled training.
Feature lift
130kgBench Press
Achieved in May 2026 at age 17 after breaking through a long plateau.

Mar 2025100kg bench
2025 PlateauStayed around 100kg for most of the yearA long plateau around 100kg made progression slower, but also made the jump to 130kg more meaningful.

Progression Through Patience
Progress has not always been linear, especially during long plateaus, but consistency has mattered more than quick jumps.
Strength With Control
Numbers matter, but only when the lift is controlled and repeatable.
Training Partnership
Training with Adam H has made progression safer, more competitive and more enjoyable.
Having one consistent person to train with creates routine, accountability and the confidence to push close to limits without doing it alone. Adam is usually about a plate ahead on many exercises, which creates something to chase while keeping training fun and structured.
Testing Limits Carefully
I like finding my limits across different movements, while building the consistency and control to do it properly.
Transferable Discipline
The discipline from training carries into school, projects and sport.
Calisthenics Control
- L-sit to handstand
- 50+ push-ups in a row
Weighted Strength
- Bodyweight +80kg dip, 1 rep max
- Bodyweight +45kg pull-up, 3 reps
- Bodyweight +20kg muscle-up
