Some of the Projects completed are:

UK's Cultural Events Knowledge Graph and web-based app

Final dissertation project for MSc. at St. Andrews. The main objectives achieved from this project are:

• Created an ontology using data models for events and places for representing the information in the data set.
• Created a Knowledge graph (KG).
• Designed of SPARQL queries to query the KG.
• Then developed a web platform to interact with this List Knowledge graph for extracting and displaying information visualizations and graphs.

PySpark project for a Movie recommendation system

The movieLens dataset was used to allow the user to search different movies according to year, movie ratings and most watched. A movie recommendation system was also developed using K-means clustering to give recommendation according to the user's taste.

COVID-19 Global Data Visualization project

A heat bubble map using d3.js and mapbox showing the affected areas of the world by bubbles or circles since the start of the pandemic. The visualization is interactive and can be used to view the spread since the start of the pandemic. It also allows a user to hover over the map to get the exact number affected and deaths in the countries.

Vector Drawing app

A simple vector graphics drawing program using Java Swing. The program used the Model–View–Controller (MVC) design pattern to give the features such as:

• Free hand writing
• Drawing straight lines
• Drawing rectangles
• Drawing ellipses
• Drawing diagonal crosses (see the figure below)
• Undo/redo
• Different colours

A simple Java web server which can respond to some HTTP requests

The server takes two command-line arguments: the directory from which your server will serve documents to clients; and the port on which your server listens.

Features include:

• The server supports and respond correctly to HEAD requests.

• The server supports and respond correctly to GET requests.

• The server returns HTML documents requested by a client.

• The server responds with appropriate error messages when non-existent services or resources are requested.

• Returns binary images (GIF, JPEG and PNG).

• Multithreading – supports multiple concurrent client connection requests up to a specified limit.

• Logging – each time requests are made, log them to a file, indicating date/time request type, response code etc.

• Supporting other methods OPTIONS and DELETE.

MSc. Research Project: Terahertz for diagnosing Cancer

Researched the use of Terahertz for diagnosing Cancer, and also developed a business model for bringing it to the market.
