4+ years
Academic & Practical

Education

B.Sc. Computer Science, TU Dublin

I’m a third-year Computer Science student with a strong foundation in web and app development, software testing, and cybersecurity. I thrive on turning ideas into responsive, secure, and accessible digital solutions.

My interests include full-stack development, cloud technologies, DevOps practices, and ethical hacking. I’ve completed intensive hands-on projects in web apps, AI, digital forensics, and secure software architecture.

Through Udemy courses and self-learning, I’ve acquired certifications in cybersecurity, file automation, digital forensics, and web development. These experiences have strengthened my skills in version control, deployment pipelines, secure coding, and troubleshooting real-world systems.

I’m constantly exploring new technologies, with a passion for building inclusive, scalable, and efficient digital solutions. I enjoy working on complex problems, contributing to collaborative projects, and continuously developing as a modern tech professional.

Projects

iPlanit Website Redesign

Led a team project, in collaboration with SJOG co-designers, to redesign the "Action Plan" section of the iPlanit platform. We focused on user-centered design, accessibility, and inclusivity, using feedback from real users and accessibility audits.

Used React, Next.js, and modular CSS to create an interactive goals interface with dynamic states, progress tracking, and persistent local storage. Implemented accessibility best practices using semantic HTML and ARIA.

Tech: React, Next.js, JavaScript, HTML5, CSS3, ARIA

Country Search App

A real-time, case-insensitive search engine for country names with a user-friendly and mobile-responsive UI. Users can search by full or partial country names, with search results powered by a MySQL database and server-side filtering.

Includes a fully structured backend using Node.js with Express, and interactive JavaScript DOM logic for seamless user input handling. Supports future upgrades like fuzzy search and caching.

Tech: Node.js, Express, MySQL, JavaScript, HTML5, CSS3

AI Neural Network Classifier

Designed and trained Multilayer Perceptrons (MLPs) for classification tasks such as XOR logic gates, Iris species prediction, and transport mode classification. Explored the effect of tuning hyperparameters and training rates.

Integrated cross-entropy and MSE cost functions for performance benchmarking. Project documented in Jupyter Notebook with annotated visualizations.

Tech: Python, NumPy, Pandas, Jupyter, Matplotlib

Cryptography and Cybersecurity Labs

Practical experience in encryption, password cracking, and network security using tools like Hashcat, Hydra, GnuPG, CeWL, and Wireshark. Simulated password attacks, RSA-based encrypted messaging, and digital forensics with real datasets.

Built secure communication pipelines and implemented brute-force testing, vulnerability scanning, and malware analysis using Kali Linux.

Tech: Bash, Python, Hashcat, GnuPG, Hydra, Wireshark, Linux

TunePal App Testing

Led comprehensive software testing of a music library app across the full SDLC. Designed unit tests, user-focused usability tests, and evaluation strategies. Created personas, test cases, and ran evaluations using SUS, heuristic checks, and scenario walkthroughs.

Reported bugs, planned test strategies in Scrum cycles, and wrote functional and non-functional requirement validations.

Tech: Python, pytest, UX personas, usability testing, Scrum
