Experience

Cybersecurity Project

This project involved working on a phishing simulator that sent out phishing email simulations to detect users who clicked the link inside the emails or responded with personal details. Based on the data, users were required to learn more about phishing and how it can be detected.

Car Technical Verification Tracking Application

This Ruby on Rails application is designed to manage and track the technical verification status of vehicles for both individual users and companies. It maintains comprehensive records of users, organizations, and their associated vehicles. The system automatically sends notifications—via SMS or email—to alert users ahead of their vehicle verification expiry dates. Additionally, administrators have the ability to manually trigger notifications for vehicles due for verification in the upcoming month.

The user interface is implemented using Bootstrap and HAML within the Rails application itself, utilizing straightforward Ruby views without a separate front-end framework.
