Experience
Android App for Stagecoach UK
I was a lead programmer in this project and responsible for creating project architecture and foundations. The app was using reactive patterns and a number of standard Android libraries
iOS App for Greggs Fast-Food Chain
The app was built using MVVM architecture, using behavior pattern and extensive use of observers.
I was the only iOS programmer, building the app from scratch to the first released version until I was assigned to another project.
Android App for Canon Europe
The app featured content downloaded from the CMS with many different custom presentation types such as exercises, interactive maps, lenses comparisons, and more.
I was lead programmer of Android version of the app
CityBcon - Dublin City Guide with iBeacons
I developed this application from scratch, including the design of UX and advising the client on how to best implement the required functionalities. Two apps were created - a fully featured iOS app and a limited-in-functionality Android app. I also extended the existing back-end CMS app to provide API required by the application.
Unfortunately, this project was canceled due to business reasons.
Corporate Banking System for WBK
The objective of the project was to create a web-based front-end for corporate clients that would replace the existing stand-alone application and offer, at least, the same user experience as a native app. The secondary goal of the bank was to push as much processing, such as sorting or filtering data, as possible to the client app to avoid server strain. This meant we had to make sure that the app would be able to handle thousands of records without degrading performance.
We were using GWT and PureMVC for front-end, and Spring for the back-end. All the data and business operations were handled by bank core systems, exposed as SOAP WS, so it had to be processed before sending to the client.
I was the lead programmer and co-author of architecture in this project.
Document Flow Management System
My role was to propose the architecture - my main goal was to make it lighter and easier to develop, hence I proposed significant changes to the technology stack used - like using Spring and Dependency Injection instead of Service Locator (which was standard in J2EE), iBatis instead of pure JDBC, etc.
I was the technical leader and product owner, managing approximately 20 people, helping them to solve difficult problems and making sure that the whole work produced would be consistent and fit together.
Public Information Portal System for Local Governments
I managed a team of two other developers and several consultants and graphic designers.
During this project, I developed a custom HTML parser to clean HTML code produced by MS Word (most of our clients had their materials prepared in this format) that provided much better results than any available software at that time.
