Dublin, IrelandA personal introduction

Hi, I’m Hugo.

I build software, and look closely
at how it behaves.

I’m studying Computer Science at University College Dublin. My interests are in AI applications, backend development, data modelling and software reliability.

01 / Selected work

A closer look.

Two projects I’m still working on. Here’s what they do, some decisions behind them, and what remains unfinished.

AI learning companion

PaperScope

An AI learning companion for my own long-term study across multiple subjects, with reusable materials and answers I can check against their sources.

What happens when a citation is real, but doesn’t support the answer?

In developmentSince November 2025

02 / A little about me

From data science
to the software
around it.

Python · Java
My programming starting points

My background is in data science. I’m now studying for an MSc in Computer Science at UCD, exploring AI applications and the software around them.

Python is my main programming language, and I also work with Java. I studied C and C++ through programming fundamentals and algorithms courses. I’m interested in trying different areas and building on those foundations.

Education

A little industry context

Guizhou-Cloud

Data products · Internship

I contributed to two data products focused on policy matching and tender risk. My work included policy-matching rules, risk indicators, product documentation and architecture diagrams.

Beijing Jiqun Technology

AI software research · Internship

I researched AI software in accounting, legal services and document storage, comparing products, user needs and business models.

03 / Outside of work

Other things in the mix.

Learning to make music

I’m learning music production. I also take part in a music society — another way to make space for music alongside my studies.

A book, and a conversation

I like reading and attend book clubs in Dublin. I also take part in the Harry Potter society and the Mature Students Society.

Away from the laptop

I enjoy films and cooking, too. A film to watch or something to cook makes a welcome change from studying.

Get in touch

Let’s talk.

I’m looking for software engineering, AI application and data internships or graduate roles in Ireland. Questions about my projects are welcome, too.
