I've been working as a software developer for over seven years, started my career programming in Visual Basic .NET and later switched to C#. I developed several software in the industry, the most prominent if I gave a data collector created by me in Java with Android Studio where I made the company' s customers reduce their equipment costs by 35%, every barcode scanner was performed with the cell phone camera, making it necessary to buy a cell phone and not more fully specialized equipment. In 2017 I reached the end of one of the largest hackathons in the world offered by NASA (link: [login to view URL]) and since that year I have specialized in blockchains, from writing white paper, integration among public networks of blockchains, to programming in Solidity (Smart Contracts), my main specialists today are blockchain Bitcoin, Ethereum, Ethereum Classic and Hyper Ledger.
