Your problem is my problem. My focus had been windows and Linux system applications, game engines and desktop applications for major software companies in US and Canada. Since 2009 I specialize in mobile applications and web site. During the course, I learned various mobile/website development frameworks, seasoned with experience and in-depth knowledge of the mobile/web applications.

    “First: whoever is behind this account is misusing the photo and the name. When I spoke with them on chat over first contact. I could hear at least 3 people in the background and all of them male. My bad for trusting them at all. I should have dropped the bid immediately right there. Second: the job description was very simple - 1h support debbuging some HTLML & CSS for a front-end site developed in MOBIRISE. They would receive the files in advance and then over chat they would point out at the code error so I could fix it. They worked well the first time even though they didn't know anything about Mobirise and didn't even download it. The next time they started arguing about the money. The third time they started stalling and waiting forever trying to extend the 1h to a longer period of time. ABSOLUTELY TERRIBLE TERRIBLE TERRIBLE Customer service. Even though the job was very simple most of my time was waisted arguing about money or time.”
