About Me

Hey! I'm a software developer from Dublin. I've always had an interest in technology which is why after finishing up in school I went straight to college to study computing (specialising in software development). After finishing my degree I got a job as a software developer in the Fintech space, working for a challenger bank called Fire, 5 years later I then moved on to work for ICE, who owns the New York Stock Exchange. Last but not least, I'm now working for Mastercard. Interested in all things tech, fintech and cryptocurrency


Feel free to get in touch using the contact form at the bottom of this page. In the footer there's also links to my Twitter, LinkedIn, Github and Medium account if you prefer any of those!

Experience

Mastercard

Lead Software Developer

Currently working for Mastercard, developing a reverse proxy service which handles authentication and authorisation across the entire company, for both internal and external websites.


  • After a year working with Mastercard, I got promoted within the same team.
  • Actively involved in designing detailed design documents, architecting scalable and efficient system designs, leading and mentoring the rest of the team and ensuring that all parts of the SDLC are followed from start to finish.
  • Chosen to be part of a small group within Mastercard called "Bar Raisers" to ensure that we're hiring top quality talent by conducting interviews across the company.
  • Due to the nature of the product (a shared service used by hundreds, if not thousands of applications within Mastercard to handle their authentication and authorisation), security is top priority. This has always been the case in my career due to my previous roles being at a challenger bank and the New York Stock Exchange.

I've worked on lots of side projects in the past, almost too many to mention! From messing about with basic HTML sites and WordPress sites when I was a teenager to some more advanced projects like what's below. Below you'll see 1 project from a range of types of software I've dealt with including: cryptocurrency, an android app, an Amazon Alexa skill, a website with a backend built in Java and using SQL and finally; a Chrome extension.

The vast majority of things that I've worked on lately are also Open Source on Github so feel free to take a look!
