A simple Tic-Tac-Toe game implementation in C# using window based components. The user is greeted with the game setup form to select the blue or red player. Then, the game starts off in a five by five grid of clickable elements, similar to the traditional Tic-Tac-Toe setup. The user is tasked to beat a naive computer player that is configured to make random moves by selecting empty spots on the game board. As the game progresses, we check whether our win conditions are satisfied by checking diagonal left, diagonal right, horizontally and vertically. Depending on each player's moves, the game can end in a win or draw state.

A simple console based airline reservation system written in C++. Users are able to select existing flights determined by unique flight codes, view the list of direct and connecting flights, create and manage flight routes and make passenger seat reservations. Sample flights are included from and to Athens, Thessaloniki and Patra cities. The project has been developed with data structures in mind, using object oriented programming and utilizing data structures such as Linear Lists and Linked Queues.

An advanced Android application that was developed as a university assignment for the subject of Software Engineering. The app is based on Google's Firebase platform. Users are able to easily authenticate with their Google accounts. Real time chat with a hypothetical licensed doctor, in-app and system wide alerts on major catastrophic events, a panic button for emergency calls, a driving mode that notifies of speeding violations and a disability mode for fall detection. This software was developed in phases based on RUP with detailed UML diagrams.

A simple Android application that was developed for the subject of Software Engineering. The app uses Google's services to determine the phone's location and creates a local database to keep track of speeding violations. The user is able to set the upper speed limit (km/h) and start or pause speed monitoring on demand. When a speeding violation is detected, the app notifies the user with characteristic sounds and text-to-speech messages. The longitude, latitude, speed and timestamp of the violations are stored locally and overlaid on a Google Map.

A Python project that was developed as a university assignment for the subject of Bioinformatics. The goal of this assignment was to process hypothetical sequences of nucleotides on seven different scenarios. The Biopython library is used for biological computation. The Needleman-Wunsch algorithm is utilized for sequence alignment along with Hidden Markov Models with the Viterbi algorithm.
