    Software Developer/ Software Architect/ Web Developer

    New Zealand - Last active: 21 days ago - Tests: 14 - Portfolio: 12

    Having worked in desktop, mobile, automotive and web industries for 8 years gave me quite an experience in software development, architecture and design. This also resulted in me being too lazy to get up early in the morning for the sole purpose of getting to the place where the computer is located. So here I am, a happy down-shifter with a diverse skill set. Currently, most of my time is wasted on the web design and development. I also enjoy doing some graphic design, logo design in particular. You have some kind of a job needed to be done? Do not hesitate to contact me, and maybe (in case I am available) it will lead to a long and productive relationship resulting in prosperity for both sides. P.S. When I learn something new I usually update my skills above.
