I build backend services and full-stack applications with Java, Kotlin, Spring Boot, PostgreSQL, MongoDB, and SQL, with a strong focus on clean architecture, maintainability, testing, and reliable system behaviour. I also work on Android projects in Kotlin and Python-based services with FastAPI, including AI-oriented integrations such as RAG workflows and LLM-connected applications.
Full-stack travel discovery platform that collects live flight offers from Dublin, stores and normalises fare data in PostgreSQL, and uses an AI assistant with RAG-style retrieval to recommend trips by mood, dates, destination type, weather, events, and price. The system includes a separate ingestion pipeline running on a VPS, a Spring Boot API, a React frontend, and an assistant service deployed online.
Full-stack restaurant ordering platform with REST APIs, authentication, and database integration. Designed with layered backend architecture to simulate real-world restaurant workflows and user-facing order flows.
Real-time tracking and notification system that records boss kills, calculates respawn timers, tracks tomb locations, and sends Discord alerts to improve coordination through persistent state management and time-based logic.
Machine learning project analysing Census 2022 data across roughly 19,000 areas in Ireland. Uses K-Means clustering to uncover territorial socio-economic patterns beyond traditional urban-rural classifications.
Academic software engineering project covering requirements, UML design, implementation, testing, and documentation using a structured SDLC approach.
Small Android projects demonstrating Kotlin development, Android architecture fundamentals, UI handling, state management, and API-driven mobile interactions.
Normalised database project focused on historical migration data, schema design, data integrity, and query efficiency.
Concept project for an educational museum environment, designed to improve storytelling and visitor engagement through interactive mobile experiences.
I'm currently open to junior and graduate opportunities as a Software Engineer, Backend Developer, Java Developer, or Kotlin Developer in Ireland and across the EU.
