My projects

Mass Shootings 1982 - 2020

Using Python, I analysed the data on US Mass Shootings provided by Mother Jones from 1982 to 2020.

In order to get answers for the research questions, the data needed to be cleaned, prepared, updated, explored and visualized.

Python | Pandas | Jupyter Notebooks | Numpy 

Speed Analysis (Tableau)

Created an interactive Tableau dashboard in just one hour, analyzing the top Spotify songs of the year. Focused on delivering fast, visually striking insights—highlighting trends, genres, and artist popularity with clean, intuitive design.

Tableau | SQL  

Real-World

I created a Honeypot and waited for attackers to fall into the trap.

In this project, I implemented Azure Sentinel, a Security Information and Event Management (SIEM) tool, to monitor a “honeypot” I created—a deliberately vulnerable system designed to attract and analyze malicious activity. 

 

Azure | Sentinel | Virtual Machines | Firewall Setup | Powershell 

Threat Hunting (Elastic)

I investigated the intrusion of malicious software called “Stuxbot” using the Elastic Stack.  Using the provided IOCs, I looked for any signs of compromise using KQL queries and the logs provided.

KQL | Elastic | Sysmon Logs 

This is my project

I created a ransomware program in Python using the cryptography library in Python called Fernet.

The program adds the targeted files to a list, and then encrypts them all.  

The decryption happens only after the input of a “secret phrase”.

Python | Bash | Linode

Weather on project

I created an app with React using the NASA Weather API that feeds real-time data with temperatures and wind on Mars.

VS Code | React | Javascript | HTML | CSS
