After completing my Leaving Certificate, I spent ten years working as a barman. I had always had an interest in fixing computers and IT networking. I decided to enrol in the Computer Networks & Cyber Security course in BFEI. I found all the elements of the course very enjoyable and instructive. Having started from a position of having little experience with the inner workings of a computer, the course gave me great confidence in assembling and disassembling computers. The hands-on elements of building and troubleshooting IT systems were very enjoyable. Shortly after completing the course, I started work as a Technician with CompuB, I am now employed by Milestone Technologies as an IT Technician, currently I am sub-contracted to work in Facebook. The work is very interesting and varied. I am delighted with the choice I made to go to BFEI, it has opened many doors for me that otherwise would not have been possible.
