Some things I do for fun

One of my favourite hobbies is making hyperrealistic digital and watercolour paintings of animals and portraits of people. I also love just letting loose and editing videos of trips I've had, creating motion design concepts for songs and designing high-fidelity Figma prototypes of various ideas - mostly to get out of the box every once in a while!




Figma prototype: American Wellness App

This prototype focuses on converting American Wellness website visitors into App users, with the goal of providing a personalised experience and a chance to avail of a free trial to a premium subscription.

It also displays the use of a native iOS component showing accessibility options to readers, such as increasing and decreasing font-sizes, with a demo of the Dark Mode feature. Native components ensure an app can be shipped with ideal accessibility standards while preserving device performance.

Motion design: Lavery's "The Mist" lyric video

Using nail polish, water and After Effects I've edited this video for a dear friend so she can promote their single "The Mist".

Lavery is a jazz collective based in Dublin with influences from brazilian samba and psychedelic music. I was tasked with capturing their essence through this song and I went back to my crafty roots to get there!

Figma prototype: Save a Fox

A mobile landing page I've designed just because I have a soft spot for motion design and foxes - and I love the Save a Fox initiative!

I wanted to make a really beautiful landing page prototype concept for this american non-profit. Hope you enjoy it! If you do, why not actually give them a follow on Instagram? :)

Motion design: Imagine Dragon's "Amsterdam" short lyric video

I've made two videos of the same trip to Amsterdam a few years ago, and one of them is this stylized short video done in After Effects.

Video editing: 4 Days in Amsterdam (2018)

Using various video editing and shooting techniques I've learned over the years, I made this video to save a moving memory of one of my favourite places in the world. Hope you enjoy it!
