Rodrigo

• Design of J2EE architecture to be used in the construction of new systems for the company and customers.
• Design of web applications with synchronous and asynchronous behavior and interfaces with ERPs and other systems.
• Analysis of the J2EE system to identify bottlenecks and failures in architecture/modeling and propose improvements.
• Development of new frameworks to be used as a basis for the development of new systems.
• Proof of Concepts of market frameworks to define which ones will be the company’s official standards for new developments.

• Currently working on a web application that validates invoices issued in the corresponding Brazilian state and bookkeeping them in the ERP. The main characteristics are asynchronous web service messages between the application and the states and the integration with ERP.
• Functional analysis, and requirements gathering with users and clients.
• Creation of functional documentation and use cases for the developer.
• Full Stack Development in Scrum and Test Driven Development.
• Development of new features, unit tests, and, maintenance of existing ones.
• Development of Integrations between Java and various market ERPs like Oracle EBS, SAP, JD Edwards, and legacy systems.

Technical Lead and developer as an Independent Consultant for a project named SGOE developed on SOA architecture for Telefonica. The end customer was PRODESP (Data Processing Company of São Paulo State).

• Management activities of the development team.
• Focal point in technical meetings with Telefonica and other software teams negotiating solutions and delivery dates.

• Java Instructor at Sun Microsystems from 2001 to 2012.
• Over 100 trainings given to more than 2,000 people. Students’ approval evaluations were always above 90%.

• Java Instructor at Oracle from 2001 to 2012.
• Member of Oracle’s specialists’ instructors team (09/2002 a 12/2005): as a Java Specialist Instructor responsible for reading and analyzing new course materials, creating a guide with hints about new and/or complex topics for the rest of the instructors.

Unified Document Input Interface (10/2013 to Present)

Unified Document Input Interface is a software to help Brazilian companies in fiscal matters. Roles are Java Architect and Senior Java Developer.

• Main features of the software:
  • Downloads issued invoices (XML files) to a specific company in each Brazilian State Web Service and store them in a local database.
  • Bookkeeping invoices into SAP (ERP) automatically by reading XML files.
  • Reconciliation between issued invoices and bookkeeping invoices.
  • Allows users to register materials arrivals and departures.
  • The software has an asynchronous and multithreading behavior and the main technologies used are Java 8, Camel, Quartz, Eclipse MOXy, JPA, Hibernate, Spring, POI (reports), JavaScript, and jQuery.
  • It runs in Tomcat and with PostgreSQL, MS SQLServer, and Oracle.
  • For development we used Maven, JUnit, and Mockito.
  • Responsible for software architecture and some developments.

ERP Connector (10/2013 to 12/2017)

• Client needed to extract Brazilian invoices data from its ERP (Oracle PeopleSoft ERP, JD Edwards, Oracle EBS, SAP) to be delivered, via Web Services (REST), for the issuer software. I developed an application that was set as a  windows/Linux service that read some tables (inside some ERPs) and throw TCP (for SAP) to identify if there were some new invoices available to be read.
• Technologies: Java Quartz, Spring Framework, Spring JDBC, JCo, Apache Camel, Oracle Database, Maven, JUnit, Mockito, DBUnit.

SID – Delivery Information System (04/2005 to 12/2012)

• Sun Microsystems Educational Services had a static page with instructors and course information. They used that pages to find out which instructors were able for each course. Was hired to replace that. The replacement application (SID) was developed with Java, JavaScript, Hibernate, Velocity, JavaScript, Struts, MySQL, and PostgreSQL databases and was deployed in Tomcat. For development skills used were Maven, JUnit, and Mockito.
• The application allowed users to manage instructors (certifications, enabled courses, availability for classes, …), and courses (level, category, version, …) and search which instructors were able for each course.
• After the first release many others were developed. SID remained in use until Sun Microsystems was bought by Oracle. At the end, SID controlled the entire course workflow except for room allocation, which was: manage instructors data:  certifications, enabled courses, availability for classes, …manage course data: level, category, version, instructor kit, student kit, last release, last release printed course material workflow: manage last printed release, order process to
  print new releases. In 2010 I migrated some Struts features to Spring 2. x, like exception handling, URL mapping, transaction interceptor, message source, and view resolver.
