Core Skills

Technical Lead

As a technical lead and mobile developer, I've helped large and small businesses across the world successfully deliver mobile applications.

I've run mobile development teams over three continents, and I'm an experienced technical lead capable of delivering software with developers in the UK and abroad.

I've delivered mobile software on a variety of platforms including iOS and Android, into the consumer marketplaces, into large corporates and into the public sector.

Mobile Payment Applications

My specialization is in payment card applications. My mobile apps have taken tens of millions of transactions, with contactless payments, EMV and swipe.

The applications scale into hundreds of thousands of merchants. I have expertise in PCI compliance, PED integration over Bluetooth (including devices from Miura, Verifone and Ingenico) and hardware integration into Android and iOS over USB.

API Design

Quick, accurate, detailed and precise designs of API to co-ordinate different development teams

My Business Hub

The application is available for both iOS and Android, and I have daily hands-on sessions with developers in both areas, providing guidance, support and getting my hands dirty with code where necessary. I work on source code every day, producing PCI-DSS compliant applications.

Currently being piloted on Android, My Business Mobile is the world's first mobile terminal implementation to be full approved and accredited.
