This is a Native iOS writen in Objective-C, Core Data. I was responsible for end-to-end technical implementation of new features, deciding technical architecture, writing code, integrating with ING backend API, setting up CI/CD process using XCode Server, deploying to App Store Via TestFlight. I have also solved an interesting and challenging issue of the app, a bug that stopped some ING customers to log in due to expired auth information.
Working with product owner, UI/UX and other backend developers to develop the front end of the CRE iPhone app that let users to:
I was the lead iOS developer and worked with product owner UI/UX designers, backend developers to build Viator Tours and Activities app for iPhone and iPad.
The app provides users with more than 10,000 tours available in 900+ destinations around the globe. It sells about $5 million worth of tours annually and was rated top 10 travel apps in the App Store in 2012.
Some of the app features:
The app was a native iOS app and written in Objective-C, heavily relied on Core Data to store Tours and Destinations to provide users instant access to travel information without too much network requests. The entire app IU including the comprehensive checkout process was written in native code manually with minimal use of Xcode Interface Builder to maximize flexibility and performance. The most interesting challenges were to use Core Data with multithread and alway thinking about writing efficient code to optimize performance on old iPhone 3G, 3GS due to limited hardware capabilities.

I have worked with business stakesholder, UI/UX designers and other developers to build the front end of TAB iPhone app with Objective-C and its API web services in C#.Net.
Some of the app features that I have helped to develop:
One of the challenge was large and complex datasets. Build an API to process and transform data from multiple sources to provide a clean dataset for the app. Using TouchXML library for parsing XML data in an efficient way that doesn't consume much device memory.
I have worked with product owners, UI'UX desingers and other iOS and backend developers to maintain and refine the Luxbet iOS universal app. I have also helped to develop the new Cash Out feature of the app.
Developed a Web Portal with a CMS system and integrated racing data information for RVL. With more than 30 year history of racing information, it accumulates rather large amount of data which makes it challenging to extract and present racing information in real time to a vast number of web users, espscially during racing seasons.
My job was to be a technical personel to analyze and optimise the racing data platform to improve perforamnce, data ingegrity and most importantly to increase the system capacity. The production of this website has received a great feedbacks from RVL as well as its users and other racing organizations in terms of usability, productivity and especially data accuracy and responsiveness.
