Software portfolio for early-career roles in software engineering, test automation, and platform / cloud engineering.

I am currently completing a Postgraduate Diploma in Software Development, Cloud Computing and DevOps at the University of Galway, building on prior experience in healthcare, clinical research, data, and regulated environments where accuracy, traceability and delivery discipline mattered.

Early-career software engineer focused on backend development, distributed systems, cloud, CI/CD, automation, and test automation. This portfolio highlights hands-on projects across Java, Python, Flask, Firebase, Spring Boot, React, Jenkins, GitHub Actions, Docker, MySQL, and AWS.

HiveWatch Lite (hivewatch-lite)

Full-stack Spring Boot and React application for managing hives and temperature readings, used to demonstrate layered testing across the back end, front end, browser smoke checks, and supporting reviewer-facing test artefacts.

What it shows

• Full-stack development using Java, Spring Boot, React, and TypeScript
• Layered back-end design with controllers, services, repositories, DTOs, and JPA
• Domain behaviour including CRUD, search, filtering, relationships, aggregation, and API-driven UI flows

Distributed Flask Wiki Cache App (distributed-flask-wiki-cache)

Three-tier distributed Flask web application with a front end running on an Ubuntu virtual machine, a remote Wikipedia lookup executed over SSH on Amazon EC2, and a MySQL cache running in Docker on a separate Ubuntu virtual machine.

What it shows

• Python and Flask back-end development
• Distributed application flow across host, local virtual machines, and AWS EC2
• Remote script execution over SSH using Paramiko
• Dockerized MySQL caching with a cache-aside retrieval pattern
• Environment-based configuration for machine-specific values
