I have participated in several projects covering financial, charging, customer relationship management and sales force automation. Actually I'm working in a project some colleagues and I have started, our goal is to deliver a high-available environment in the cloud, where users and also skilled developers, can build solutions in the cloud with a friendly interface, without having to worry about infra-structure, storage and complex technologies, such as web, application or database servers.I try to collaborate with the open-source community in some projects, specifically the ones I'm currently using in a daily basis with information and sometimes with solutions as well. As a full-stack developer and systems architect, I have acquired knowledge designing and building solutions in complex, high-available and scalable environments. The technologies and frameworks I mostly use are: - Amazon AWS (ELB/ALB, EC2, RDS, Route53, CloudFront, S3, Lambda and IOT); - Jersey, JacksonXML, JAXB and AXIS for SOA / RESTful APIs; - Spring Boot, Security and Data; - AngularJS, jQuery and Bootstrap; - JavaSE 8; - Advanced ECMAScript 5 and 6 (JavaScript); - SQL Server and Oracle as RDBMS; - MongoDB or DynamoDB as NoSQL Databases; - memcached and/or redis for application cache.

Listed skills include Java, Jboss Application Server, Java Enterprise Edition, Hibernate, and 46 others.
