About

I'm a software engineer with 10 years of experience across diverse sectors and roles. My career has evolved into a senior tech lead role where the projects I'm responsible for delivering are shaping the direction of the organisation. While I excel at leading technical projects and acting as a bridge between my engineering team and senior leadership, my true passion lies in writing code, obsessing over design details and shipping features.

Projects

Putting Pals

Putting Pals

React app

Started several years ago as a friendly competition among friends to bet on winners of major golf tournaments. It's evolved from a simple spreadsheet into an over-engineered web application. I've rewritten it many times as a playground to test out new technologies so it may be in a WIP state depending on the time. Most recently I've swapped out GraphQL for tRPC.

Inter Club League

Inter Club League

React app

My cycling club runs a friendly racing league with several other clubs each year. Weekly info is posted across multiple platforms and people often had trouble finding the relevant info for each race. I built this to consolidate all the schedule, race locations and results in a single place.

Stonks

Import your Fidelity data and automatically calculate how much capital gains tax you owe. For Irish tax residents only.

Dublink

Dublink

Android app

An Android app for public transport in Dublin which integrated with APIs from Dublin Bus, Irish Rail, Luas, Dublin Bikes, Bus Éireann and Aircoach. I offered a paid version with extra features which earned a grand total of €12 (twelve euro).

Dublin Bus Pal

Android app

The first side project I worked on which I got into a finished enough state to publish on the Google Play Store. It had over 10,000 downloads and was often mistaken for the official Dublin Bus app.
