To whom it may concern

            Patrick Jackowski was one of the better students I have taught on the foundation degree program. A very intelligent and driven student who I could see doing extremely well in any IT role he chooses to do. The modules he covered directly with me (Cisco and Linux) he scored extremely high. He also went on and did additional work covering Wireless and operating systems not covered directly on the course. Overall he was a high calibre student who did very well on the FdSc.

            I have no issues in recommending Patrick in any role in IT and Comms.

Dear Sir/Madam,


I am writing to confirm that Patrick has worked for us as Network Manager for the past 2 years. 

During that time Patrick has worked hard to ensure our 4 separate networks were efficient and working properly. He has maintained the systems for us efficiently and well. He dealt with the administration of the LINUX and Windows servers. He ensured that we had the correct equipment and we were advised promptly when equipment needed replacing.

We have been very happy with Patrick’s contribution to us and he has worked very well with us in often difficult circumstances. He will be very much missed.

Yours faithfully
