DECENTERNETIT Infrastructure Engineer

Apr. 2017 - Nov. 2018Gangnam-gu, Seoul, KoreaDecenternet is the most powerful complete hyper-speed P2P decentralized internet infrastructure solution that blockchain technology can create. It doesn’t belong or report to any third-party organization except for its users. Its innovative browser technology allows you to experience a much faster, more secure, and more private decentralized internet along with the traditional websites you are used to. Data on the Decenternet can be searched and retrieved by the Decenternet Liberty search engine. Liberty does not have an intermediary company to report profits to. You can imagine the information on the Liberty search engine will eventually be more powerful because it is not suppressed by a third party. All of this will be experienced by simply installing the Decenternet wallet and browser application on your computer. All economic activity on the Decenternet is conducted in Spice obtainable through domestic mining. Spice is an appreciating currency that is interchangeable with most major cryptocurrencies, such as Bitcoin, Ethereum, and EOS, neutralizing the need for pointless competition among major cryptocurrencies. This naturally allows the invaluable technology each of them represent to coexist in harmony within the decentralized Decenternet exchange. Spyce is the essence of all trade and commerce on the Decenternet. Spice can be used to purchase hosting services, apps, or goods, or process micropayments with ease. This creates a free-market crypto economy where renting out hard-drive space and computational resources such as RAM, CPU, and bandwidth to support the Decenternet can be lucrative. There will always be a limited amount of Spice in circulation. Notice how the Spice economy is self-sustaining and productive in nature as opposed to the traditional fiat currency economy, which is inflationary and exhausting in nature.

ZBglobal, Inc.Web Server Administrator

Jan. 2017 - Jun. 2017Region XI - Davao, PhilippinesFrom simple, clean websites with bullet-proof secure hosting to online education, eCommerce, application connectivity, MarCom and logical, fully-responsive media, ZBglobal creates Custom Web Solutions that are alive, interactive and motivating. Technology Weaving in the Digital Workspace One of our most sought after custom solutions is getting one thing to talk to another, when they may not have been designed to do so, initially. Our core team of programmers is highly adept at analyzing and identifying the proper framework to link your vital applications… this can help you eliminate redundant input, consolidate data and streamline your workflow in an efficient and reliable manner. Making One Thing Talk to Another The inter-connected, online landscape is full of disparate systems and in-house applications that each speak their own language (known as an “application programming interface” or API). We are highly skilled at translating those APIs to create custom integrations so that data flows from one system to another, as needed, without user intervention. We can even create a custom dashboard allowing one-click access to all of your frequently-used applications. We can streamline these processes for you, in a reliable and intuitive manner, to control how they interact, and what each interacts with. This can radically increase user productivity, through the elimination of redundant authentications and manual input.
