About me

More to Life Than Code

Outside of coding, I'm into live music, pop punk, gaming and travelling to new places. Blink-182 and Sum 41 are regulars on my playlist, and I follow Spurs when it comes to football. Always up for a new experience and making memories along the way.

Beyond the code

Life outside the editor

Gaming
Enjoying highly competitive games like Rocket League and FPS titles like Overwatch.
Gym
Building strength, muscle, and overall fitness.
Travel
Discovering new places, experiencing different cultures, and seeing more of the world.

How I work

Four steps, one continuous process

1
Understand the problem
Understand the requirements, challenge assumptions and identify constraints before deciding on a solution.
2
Design with intention
Shape flows, data and architecture deliberately so every screen and every service has a clear reason to exist.
3
Engineer for quality
Write clean, type-safe code backed by automated tests, clear boundaries and reliable error handling.
4
Refine through iteration
Deliver working software, learn from feedback and continuously improve through small, meaningful changes.

What matters to me

Core Values

Clean architecture
Clear boundaries and honest abstractions that keep codebases calm as they grow.
User-centred design
Decisions grounded in how real people think, move and get things done.
Performance
Fast first paint, smooth interaction and respect for every device and connection.
Accessibility
Accessible by default, with keyboard navigation, screen reader, and reduced-motion support.
Continuous learning
Exploring new technologies while making thoughtful choices about what to adopt.
Maintainability
Code written for the next engineer, documentation that stays true.
