Experience
iOS Tablet and Phone Application
An application used by a client's personnel to plan their daily visits and routes and manage information about their customers while visiting venues. Other functions include task management, map-based tracking, extensive reporting, and an information library. I built the application UI using Ionic Framework and an API and administration panel using PHP/MySQL.

I coded the UI, built the WordPress infrastructure with many custom types, and built a custom plugin that allows the administrator to import new movie hours via Excel.
Mobile Application for a VIP Club
A cross-platform hybrid mobile application. I coded the UI using the Ionic application framework for the app, built a REST API on the server to manage the data in the application, and built an administration panel where the client can manage the members' bookings, reservations, and more.

http://www.sivilsayfalar.orgA complete rebuild of a news website that had many problems. I coded a responsive layout and the custom WordPress theme and built the necessary infrastructure using premium plugins. The new website achieved much higher performance and usability.

An Android tablet application that displays 40+ pages of pharmaceutical content in a rich media format with animation and user interaction. I created the application and built an API that stores the actions of the field personnel who use the application in their daily operations.

A custom add-on to the redbull.com CMS, where a user can create a customized scene photo and enter it into a photo contest. I built the application's server-side code and the UI, including a Canvas-based image manipulation tool.
