Backend Developer specializing in Java and Golang, with full-stack and mobile development knowledge. With over 10 years of experience, I have worked on multiple projects using the most popular technologies (Spring, J2EE, Hibernate, JPA, JMS, Rest...) in various sectors (experience with clients like SAP, Deutsche Telekom, Seat, Readisson Hotels, Hospital Sant Joan de Deu, El Periódico, etc...). Relational databases (Oracle, Postgres, Mysql, Sql-Server) and non-relational databases (Cassandra, MongoDB, redis, Elasticsearch). I have also worked with specific tools, such as the Alfresco document manager, SAP SCP platforms (NEO, Kyma, and Cloudfoundry), or the LifeRay CMS (6.0 and 6.1). My primary experience is in backend application development. I also have training in Big Data, and in Blockchain (developed smart contracts in Solidity - Ethereum platform -, including the CatCoin token, and collaborated in the creation of a contract for generating lotteries and another for automated token trading). With blockchain, I have also developed the Java library JPascalCoin for the PascalCoin currency, as well as the app for managing said cryptocurrency.
