Alex Simas Braz

I am software engineer since 2002 and BlockChain software Engineer since 2015, especially smart contracts with Ethereum and RSK. I'm a professional certified in Ethereum, Hyperledger, Corda and Bitcoin. I'm NEM and RSK technical ambassador in Brazil. We are witnessing the birth of something really relevant and transformative, and I had not seen anything like this in the last 15 years working with systems development and innovation. I am very excited about the possibilities of BlockChain / DLTs technology. Finally we have the freedom we deserve to live in a better world. Also I study and I am thrilled with the Austrian school of economics, freedom for the people, decentralization, disintermediation. I am currently specializing in BlockChain, encryption, and some of the finest programming languages ​like Java, Solidity, NodeJS. Actually working with brazilian instant payments and open finance as Solutions Architect.

My first website was in 2005, when I developed a desktop system in Java, using java 1.5, hosted at locaweb, a former service provider in Brazil. From 2013 I started using the cloud, on AWS, using only EC2 (computing) and RDS (database system). In 2015 I started using SNS on AWS, in addition I started using AZURE for startups in 2016. In AZURE I used the azure data base with global replication. In 2016 I created a startup whose focus was the development using Blockchain, starting with Ethereum, Quorum, RKS and reaching the platforms of DLT (Distributed Ledger Technologies), Hyperledger and Corda. In 2018 I became an instructor of Blockchain and DLTs by Blockchain Academy. In 2018 I returned to the financial and benefits system, and then to a fintech, where I was able to work with a digital account, card issuance, APIs for availability to customers.
