We recently have been unfortunate to experience an accidental "CHOWN /" event on our centos7 server. We have recovered and have working all production facing pages (php, apache, client side session/php session and mysql) all up and working. We still have file permission issues on a number of packages causing a few issues (that we can see): * phpmyadmin not working * security flaws due to permission mismatch This job is to return the server to a usable state, and then quote for ongoing SYS Admin work (ie. this has brought this problem and dependancy to the FORE, we need to move to a dedicated person to help with SYS admin). ON hand for any questions - between 7am and 11pm AEST preferred for work, so I can engage via chat etc when needed.

【BACKGROUND INTRODUCTION】 Have you ever thought about "cracking" the visa/ticket application system using your technique? Do you see a huge and profitable market in it? Many people in developing countries chase after popular visas in developed countries. However, places for some are limited. Take Silver Fern Visa in NZ, for example -- only 300 places each year. Such visas are great opportunities for those who want to migrate to another country. They snap up sought-after visas once the applications are opened. The ones who do faster in the applications win at last. That's why there is a great opportunity in it. You must apply for a place on Embassy's website, and machine is no doubt faster than applicants themselves. What if you develop a software to help them with the applications? What if a software takes care of everything by automatically filling in information, proceed and submit the applications? You can earn a lot just by selling the places you grab. People are willing to pay, as long as you secure them a place under the quota. Some companies are already doing this job. The price for one place varies from 800 USD to 3000 USD. A lucrative business, isn't it? Imagnie that you have 100 customers... 【WHO WE ARE, WHAT WE WANT】 We are a startup based in Hong Kong. We have a great marketing and sales team. We are looking for a partner who can develop a program, e.g. a software, to help our customers grab places for these visas! 【REQUIREMENT】 1. Proficiency in coding, software developing and network operation. 2. Fast learner. 3. English literacy. Good communication skills. 4. Sense of responsibility. 【PAY】 AT LEAST 7000 USD for the first term (Australia visa system. September 2016, 20 customers). We expect three terms until Feb 2017. This is a long term cooperation -- the more systems you "crack", the more you earn. You can organize your own tech team, if necessary. 【HOW TO APPLY】 Please apply through Upwork. Tell us why you are a good candidate.
