I offer app development skills based on standard process methodology as an experienced iOS App developer building beautiful things for the app store.

My Services

What I Can Offer


  • I Build Apps & Web Experiences

    I have been creating apps since 2012, beginning with Objective-C before moving to Swift. I enjoy solving technical problems and building reliable, polished experiences for Apple platforms and the web.

  • I Design UI/UX

    Though my skills are concentrated on the build process, I do know what good UI and UX looks like. I definitely know how to spot bad UX, and happily work with designers to plan a good user experience overall. I can make simple image edits, like all images on this site.

  • I can incorporate whatever Typography, Icons & Illustrations that you like

    Google Material Design is my go-to site for icons, but I have also purchased from Glyphish and other sources.

  • I Try to Snap Beautiful Photos

    I've been told that I have a good eye. I took every photo on the site, resized and dropped a gradient layer to pop the text out.

My Process

How I Work


Plan

The more time spent planning, the better. Wireframes, prototypes and team discussions can help steer a project away from later problems. I also use playgrounds to explore solutions and follow Apple's Human Interface Guidelines.

Build

I build with Swift and Xcode, using the architecture and interface tools best suited to each project. I create adaptable layouts for different devices and have experience with approaches ranging from MVC to VIPER.

Test

I test a lot. Usually distributing builds for test through Testflight or Firebase Distribution. I have written some automated unit-tests too, but never really get the time to completely cover everything with automated tests. Still, the QA team were happy with the quality of my releases.

Ship

I have already shipped several apps to the Apple App Store, which includes the preparation of marketing content and screenshots. I have also liaised with Apple to resolve issues that have occasionally arisen through the App Review Process.

My Portfolio

These are the apps for WheresGay, Fireproof, Dugout, and Diagnostics that I built and worked on.
I also built an Apple TV app, for Dugout and am familiar with product design practices such as wireframing. View All Items
