    United Kingdom - Last active: 12/08/2014 - Portfolio: 1

    Hello I am Jeremy (some prefer to call me Jez, my informal name), I have at least 5 years of industry experience in Ecommerce web administration and user end development (both customer facing and back office support). I take a high pride approach to my work, I would confess yes I am a perfectionist, though always get what a user wants on time and to their liking through constant (sometimes over) communication. So any shortfalls of any prospective systems are resolved as soon as possible. I previously worked for Cartridge World British Franchise Support loved my time there before unfortunately (or fortunately for me?) got left redundant last November, came as a massive shock for me, my first idea was to start and embark on a freelance career for my own making and here I am. I have a Higher National Diploma in Computer Science, can be a bit pedantic at times even with web design at my own admission (really I see this as a positive I have huge attention to detail (in fact that's my major strong point). I shudder at the people who don't have this skill which allot of freelancers lack I have come to know in the past (through my own experience with them). Basically I love setting my goals high, I feel learning is what I love about what I do, if I don't have a challenge I get not so much bored (don't want to make it sound like basic tasks for me are a bore, which they aren't (they really aren't). I like the feeling of being wanted and I like to feel wanted by my clients. I have a proven track record of getting Cartridge Worlds fist ecommerce site up off the ground and working (as referenced by my former boss Gavin Askew [now] the Distributions Manager for Britain and France. I would love to discuss your project needs and requirements and let me add something to your project and above all I have huge enthusiasm for my work (why be a freelancer in a job you hate is all I say!) Take care and I look forward to hearing from you soon. Jeremy.
