Previous projects

I've delivered web and mobile solutions to companies from all over, and independently launched my own commercially successful apps. Checkbot is the best example to look at of what I can do (all graphic design and development was done by myself).

Checkbot - Website auditor Chrome extension

I’m the creator of Checkbot, a Chrome extension that tests 100s of pages at a time against 50+ SEO, speed and security web best practices. Checkbot automates website optimisation audits that normally have to be done manually such as finding broken links, duplicate page content and insecure password forms. Everything was done by myself including the website graphic design and development, the logo, the UX design, the custom subscription payment solution and I wrote the web best practices guide that goes with the extension. Checkbot has a 4.9 out of 5 average user rating, 40K+ active users and 100s of paid subscriptions.

Skills: Chrome, browser extension, JavaScript, TypeScript, Vue, ag-Grid, Paddle, Netlify, Node, Express, Firebase, Firestore, Firebase Cloud Functions, SaaS

Fresco - Android digital painting app

I’m the creator of Fresco for Android, an easy to use yet feature packed digital painting app for Android phones and tablets. Fresco was one of the first Android apps to feature layers, and comes with configurable brushes, custom implemented image filters and robust undo/redo/autosave. The code was highly optimised to run on low-end devices: it has low memory usage, painting feels responsive with limited processing power and only requires 0.3MB to install. On release, Tested said Fresco was “the best drawing app on Android” praising its intuitive interface and the realism of the digital paintings produced. Fresco has sold 10K+ copies and has 500K+ free downloads.

Skills: Android, C, Java, JNI, UX, optimisation, computer graphics

66audio - Premium headphone brand

I was lead developer for the team working on the 66audio website, a premium wireless headphones brand. On top of backend and frontend coding, I managed the team to prevent defects going live during important product launches by introducing code reviews, a QA process, staging environments and automated testing. I helped with optimising site speed, making security improvements, introducing a multilingual solution, performing SEO audits, adding ecommerce analytics and integrating purchases using Shopify.

Skills: CodeIgniter, WordPress, JavaScript, MySQL, PHP, Google Analytics, Amazon, Shopify, Mailchimp, multilingual, Cloudflare

Triumph Motorcycles - map interactive

Working with Freak Films, I developed an interactive map experience for a Triumph Motorcycles visitor centre. The map was projected on to a 170 inch screen and displayed map pins for brand related Instagram posts and information on Triumph dealership locations. A nearby large touchscreen display let visitors pan, zoom and explore the projected map. I had to develop a custom CMS that let staff curate the Instagram posts shown and automate pulling in dealership data from an existing live database. The map display also had to function if it went offline. The experience this project was part of won a Scottish Design Award.

Skills: Chrome, PostgreSQL, Python, Django, D3.js, Dropbox, Heroku, Javascript, Windows

Cloudreach - Multilingual corporate website

I was the core developer responsible for enhancing and optimising the website for Cloudreach, an international cloud computing consultancy with 700+ employees with headquarters in 17 cities . My role included adding a complete multilingual solution, dynamic content that changed based on the perceived interests of the user, SEO auditing and optimisations, Salesforce integration, migrating to HTTPS, cloud hosting migration, analytics for visitor behaviour, theme customisation and landing page development.

Skills: Heroku, AWS RDS, WordPress, Django, PHP, jQuery, Salesforce, PostgreSQL, S3, Google analytics, SEO, HTTPS, Bootstrap

AV Search - iOS & Android apprenticeship search

I was lead developer on the team that made AV Search for the UK government’s National Apprenticeship Service. The publicly available iOS and Android mobile app lets you search and apply for apprenticeships. The project included writing a web service that lets you search through live apprenticeship data that were synchronized from another database. A core challenge of the project was managing the complexity of multiplatform and multidevice development. We used extensive automated testing to reduce defects and improve code maintainability. The app was successfully launched to the public without a single major bug needing to be fixed.

Skills: PhoneGap/Cordova, JavaScript, Backbone.js, Android, iOS, iPhone, Heroku, Python, Flask, CouchDB, Bamboo, Flurry analytics, Lucene, TDD

My background

  • Student: I grew up in Edinburgh and I’ve loved coding from an early age. I’ve been self-learning before high school and haven’t stopped since! In 2004, I completed a Software Engineering degree at Edinburgh University where I finished top of my year.

I then worked as a postdoctoral researcher on semantic web research and development. My time here improved my research, planning, writing and communication skills.
  • Software engineer: I joined a cloud computing consultancy in 2012 as a senior software engineer where I lead commercial projects from concept to completion. I was involved in presales, requirements gathering, architecture design, development, UX, team leadership, mentoring, giving training courses and recruitment.
  • Software consultant: I’ve worked as an independent software consultant full-time now for 5+ years where I’ve delivered software solutions to individuals and large companies from all over the world. I also work on my own commercially successful products where I take charge of design, development and marketing.
