About Me

I’m a designer and software engineer with over ten years’ experience. Below is a small selection of my work — for more projects and information feel free to connect on LinkedIn, or take a look at my Dribbble and GitHub profiles.

If you want my help on a project, or just want to say hello, email is the best way to get hold of me.


Soundry Co.

Complete Brand Identity


Soundry Co. make bespoke audio software. To set the company apart from competitors and to reflect its focus on whole-product design and user experience, I created a bright and bold visual identity underpinned by Suitcase Type Foundry's Nudista — the perfect match for a modern engineering outfit.

An array of brand artwork pieces gives context to the simple mono combination mark, and luxury die-cut letterpress business cards show that quality is the company’s primary focus.


Earsoft Audio

App Design & Coding


I designed and built a unique audio player app for Earsoft that tailors sound to the listener’s environment and mood. The visuals are based around clean typography and strong iconography, and the two-tone colour scheme is algorithmically generated based on a hue chosen by the user.

The implementation had to be very low level to ensure good battery life while listening, so I wrote a C library to do the audio processing, and connected it using iOS’s AudioUnit API and Android’s NDK for playback.


Cantare Ladies’ Choir

Logo & Colour Guide


Cantare needed a strong, bold logo to use on everything from posters and concert programmes to bags and embroidered coats. They already had a strong black and pink colour scheme, so I worked with the group on a combination mark that would tie their brand together.

After several prototypes and lots of feedback, we settled on a treble clef mark shaped to depict a young woman. FF Schmalhans was a natural fit for the lettering — the tall, angled characters are intended to mimic the proud, singing women.


A Happy Couple

Wedding Stationery Pack


The couple wanted a modern, elegant stationery pack, with a few extras such as a map for the day and a list of local attractions for guests to browse.

I decided on mostly black and white detail with some dark red to highlight key items. To fulfil the stylistic brief I chose Futura for labels and Minion for prose, matching each face's character by drawing diagrams with bold lines and dividing text with thin ones.
