数据库开发 Jobs

In modern times, we are realizing more than ever that some of the most important and valuable information that a company can have is its data. We know that a company’s reputation can be compromised through a data hack or leak, and that often times, the right intellectual property can add millions, or even billions, of dollars, to the market capitalization of a corporation. As a result, companies both big and small should be doing everything that they can to keep their data safe.


Database developers work to make sure that databases where information is stored is as efficient and flexible as possible, to make sure that no matter what happens, companies can have their data safe, in any situation. The right database developer can make sure that this is done at the lowest cost possible, and also avoid storing redundant data, which obviously makes operations less productive and efficient.


No matter what, data is essential. We know that Big Data is one of the biggest technological trends in the world, because it helps to illuminate information, whether it’s regarding consumer trends or scientific research. A database developer understands the important of keeping information safe, which is essential in modern times.

I wish I could devote myself to this project, but so far it is more of an art project than a source of income. My expertise is physics and HTML/JS front-end coding (in the sense that the interactive apps are entirely "front-end"). I am looking for a person to help with the business/growth side of the website, and possibly backend development.
