Hi! I'm Oisín.

I'm based in Dublin but originally from sweet, sweet Cavan. I'm a front-end software engineer at HubSpot and a recent grad from UCD Computer Science in Dublin. I had a lot of fun there playing a big role in running UCD Netsoc for three years, as well as being an organiser for a student-run tech conference called SISTEM for two years in a row (including the 2020 edition in UCD).

I've tried my hand at a lot of different tech over the past few years, but I'm a big fan of JavaScript and front-end software development (especially React). I did an internship at HubSpot doing work in React and Java and working there again now as a front-end Software Engineer.

I'm also really into music. Check out my and Spotify to see what I'm into. I had a student radio show/music/show/podcast thing called Quinntessentials where I talked about some of my favourite albums with friends. It's a good listen, I promise!

I've a few random projects on here that might be interesting:

  • dBikes Planner is an Android app and Python API for generating smart cycling routes for Dublinbikes that takes into account bike availability at stations. You can grab the code, an .apk and my Final Year Project report (I got an A+!) in that repo.
  • Amhrán is a music site I built in React that showcased a new Irish song every day (or at least until I wasn't able to keep up with updating a website daily).
  • Paper Planes was a really fun project to make: it's a distributed messaging app (aka WhatsApp clone) that was really satisfying (and a lil painful) to build.

Also here are my socials:

Cool? Cool.
