Interviewed by The Irish Times
The Irish government officially launched their COVID-19 Recovery Certificate request service today. However, they made a spelling error in registering the domain name.

Upon realizing this, I quickly registered the correct spelling to prevent scammers from phishing Irish citizens. A friend — who pointed out the misspelling — joined me in creating the website we deployed.

Covered in The Journal, The Irish Times, Newstalk, and The Daily Swig.

I interviewed electronic musician Marcus Woods (aka. Ryan Cullen) as part of my role as Staff Writer with Byline, University Express. It was promoted to the cover page of the magazine by the Editor-in-Chief.

It was a humbling experience to sit with a creative of Cullen's caliber, touching on subjects such as mental health, the music scene in Ireland, and what the future held for his musical endeavors.

The interview can be read over here.
