I work with Robert Half as a contractor, and I currently provide my services in a company called Telit IoT Platforms. In this company I work in the development of applications oriented to micro-services with the objective of satisfying the needs of the client, with which continuous integrations are made. This business is aimed at the interaction with a physical computing device HSM (Hardware Security Module), which protects and manages the digital keys that will be included in the new modules for a robust authentication and provides us with a cryptographic processing in said process.

Responsibilities:

• Implementing the service-oriented architecture integrates technologies such as Spring Boot, AWS, Docker.
• Developing micro-services to consumed Rest Services using HTTP/HTTPS methods a secure traffic (SSL/TSL) to the client with continuous deliveries.
• Using JHipster generation to creation and modeling a micro-services into Spring Boot.
• Extensive experience in micro-service development using the MVC pattern.
• Netflix/Hystrix to a Circuit Breaker integrate in the Gateway-Discovery and micro-service to give protection from and control over latency and failure from dependencies accessed.
• Using Gson to get the data from the client asynchronously by using JSON object.
• Responsible for creating database tables, procedures, functions using MySQL.
• Used Maven as a build and deployment tool, integrate with Nexus Repository Manager.
• Framework JPA has been used for the connectivity of database, and Liquidbase for database versioning. ? Netflix/zuul provides dynamic routing, monitoring, resiliency, security.
• Using of Nginx for security access control based on the IP address of the client, by password (basic HTTP authentication) and by the result of sub-abstraction.
• RabbitMQ to accepts and forwards message asynchronous in the system, and allow the integration between several micro-services.
• Using Jenkins for server automation and continuous integration with all micro-services.
• JDL -Study to JHipster is using in the entity creation.
• Generation to digital key (encrypt/decrypt) for the all modules in the system using HSM physical computing.
• Using IntelliJ in the all stage in the implementation.
• Postman and Swagger to integration testing.
• Jira as an agile project management tool.

Environment: Java8, AWS, Spring Boot, Hibernate, JPA, SSL/TLS, Docker, Angular, Netflix/Nginx, Netflix/ Zuul, Apache HTTP Server, Hystrix, TypeScript, REST, IntelliJ, RabbitMQ, Git, JUnit, TDD, UML, JDLStudy, Swagger, Maven, iText, Gson, JHipster, Postman, MySQL.

The solution also includes the definition and control of service level agreements (SLA), workflow ca- pabilities for assignment and warnings of incidents, reports, alarms, interconnection with other sys- tems and the generation of knowledge bases that help resolve faster way incidents based on informa- tion from previous records.

• Developed using Core Java and supported Java/J2EE applications with emphasis on OOP-based web forms, busi- ness logic, and database access components.
• Developed a web application for monitoring and control of SLA (Service Level Agreement) for electronic bank- ing.
• Worked on website at Enterprise level in Java/J2EE, Spring Framework, Hibernate, JavaScript technologies.
• Coding using Core Java in Eclipse RCP. Used JDBC for database connectivity.
• Designed, coded and configured server-side J2EE components like XHTML, Servlets, Java Beans, XML Parser API.
• Worked on Oracle10g database for storing and retrieving the application data.
• Designed table-less layouts using CSS and appropriate HTML tags as per W3C standards.
• Used Bootstrap UI extensively for developing the UI using the MVC framework.
• Involved in writing application-level code to interact with APIs, Web Services using AJAX, JSON, and XML.
• Implemented Transactions using spring framework.
• Used JSP Tag Libraries (JSTL) to implement the logic inside the JSPs.
• Used AJAX to get the data from the server asynchronously by using JSON object.
• Performed unit testing using JUnit framework and tested DAO's.
• Testing using SoapUI IDE for test WSDL and REST.

Environment: Java7, J2EE, SpringBoot, Hibernate, JavaScript, Bootstrap, jQuery, AJAX, REST, Eclipse, Sub- version (SVN), UML, JSP, JSTL, Servlets, iText, JasperReport, JUnit, SOA, SoapUI, Oracle, JDBC, Maven.

[Working from Office Implementation of a document management system that automates the process of sending documents be- tween institutions at the national level in Cuba. With the aim of automating processes of signature, revision, authorization, cancellation, and delivery of documents. Improve the user experience by exploiting the bene- fits of the spring framework and the Ext JS library on the web.

Responsibilities:

• Used Ext JS Framework: Asynchronous JavaScript technology used and XML (AJAX) for critical front-end vali- dations to reduce the load on the server side

• Used JavaScript for the web page validation.
• Implemented Model-View-Controller (MVC) architecture
• Design report with iReport and Jasper Server for report server
• Simulation of business processes for the change of status of different documents
• Electronic Signature with the use of SSL certificates (Secure Sockets Layer) using pairs of X 509 certificates (public key and private key), such as authentication mechanism
• Created Unit, Acceptance and Integration Test Documents and Code Review Documents.
• Used Tomcat Application Server for deploying various components of application.
• Persistence layer was implemented using Hibernate Framework.
• Involved in writing and executing stored procedures, functions and triggers for PostgreSQL to create a Database Management System.
