Salonication for iOS and Android

Salonication for iOS and Android

Salonication is an entertainment app that offers daily information on what's up in the city of Thessaloniki, Greece. All events, live gigs and more can be found right away when you hang out with your friends and cannot decide where to enjoy the night out!

I implemented Salonication app for both iOS and Android platforms. Moreover, I implemented the backend and the intercommunication between the web and the device. Backend includes a fully featured article editor which is unfortunately private and cannot be demonstrated. It was a pleasant experience, since I also acquired knowledge, experience and a deeper understanding of the iOS platform, and now I am able to develop apps on both mobile operating systems.

Clean Thess - Municipality of Thessaloniki

Clean Thess - Municipality of Thessaloniki

I am in charge of the design and implementation of "Clean Thess" an on-line platform for reporting problems around the city of Thessaloniki. The project is named "Clean Thess" after the city of Thessaloniki. The platform consists of an Android application, which is the main reporting tool and a supportive web application.

Additionally, I designed the logo (shown above) and developed the Android application, which was released on 23 Dec 2013. The website, however, is still under construction (at the time of posting). I presented my work at the city hall of Thessaloniki on 20 Dec 2013. You can download the Clean Thess app presentation from the related links.

This app can fix stuck/broken pixels by flashing colors rapidly for a prolonged amount of time. Screen burning (burn) effects can be fixed too! You can control the frequency of changing colors, the base color and the screen brightness.

It is recommended that you run it for an extended amount of time and have your device charging as well. (The screen remains on automatically.)

Mozilla Firefox and Google Chrome Addons

Firefox and Chrome Addons

I have been experimenting with Firefox and Chrome addons and I created and released some useful addons to the public, for free!

My intention is to create helpful addons that mostly serve as time savers. The reason why I created most of them was that I needed them for myself, but it seems like the community enjoys them as well!

Below you can see two of my most popular addons. Make sure you check out the complete collections from the related links!

Facebook - Delete All Messages:

Facebook - Delete All Messages

Adds a 'Facebook - Delete All Messages' button that, when clicked, deletes all listed conversations. Fast, efficient, quick way to do the hard labor.


CleanQuit (Mobile and Desktop)

Clean up the mess and quit! Adds a CleanQuit button to Firefox in order to clean up your browser and quit! You can select what to delete via the addon options.
