PROFESSIONAL SUMMARY:

• Over 14 years’ experience on IT projects, mainly, Software Development projects
• Have performed different roles like Business Analysis, Requirements Collection, Functional Analysis, User Experience Analysis, Test Planning. Though the one I enjoy the most is Software Design and Coding.
• I have even been a Project Manager, and later on a Service Delivery Manager, which were intense responsibilities I enjoyed at that time, but distracted my attention from learning new technologies.
• Regarding software design, I used to support my designs on Object Oriented Design Patterns, UML models made with MS - Visio or Sparx Enterprise Architect, StarUML, etc.
• Experienced designing ER databases and their corresponding ORM to ease their exploitation. I have also been involved on NoSQL databases consumption, though I disagree with current trending of abusing its capabilities of nesting documents to minimize the number of collections databases have.
• The databases I have used are Oracle, MySQL, MS-SQLServer, MongoDB and PostgreSQL.
• I started more than a decade ago building chats with sockets on VB, but most of the time I have spent my time on Web development, mainly with MVC and MPA, but I’ve been recently involved on the development of SPA applications. which I think is something many times natural due to some applications nature. I understand what reactive programming is trying to achieve and which Spring projects and DBMS databases are implementing it, but I haven’t had the chance to implement it professionally yet.
• The Java frameworks I have used are: Spring, Hibernate, Junit, Mockito, Quartz, Freemarker, Thymeleaf. And I would be able to understand legacy code build on Struts 1.1, Tiles; Jasper, iText and iReport, Axis services and JAXB. I have also used EasyMock, but I think Mockito is a better choice.
• On the front end, the libraries and frameworks I have used are jQuery, Bootstrap, AMD, HandleBars, AngularJS 1, ReactJS.
• On the backend I have used NodeJS and Express or HapiJS, but it feels they are reinventing the wheel and facing several issues that Java technologies have smoothly addressed several years ago.
• Familiar with Karma, Mongoose, Jasmine and Sinon.
• Regarding mobile development, I started checking out Android apps development and Ionic or React Native.
• Besides HTTP and AJAX, I have used SOAP services (with Axis 2), REST services (with Jersey) and GraphQL (with Apollo Client and GraphQL-Express). I never liked EJBs, but I have had to deal with them and transacted JMS messages. JMS and messages brokers are a pretty cool idea in my opinion.
• I have used several old versioning systems, I liked Mercurial the most (just because its shelved files are easier to use in my opinion), but I’m more used to Git and its command line. I have also used P4V.
• I have used Eclipse IDE, IntelliJ, Maven/Gulp/Webpack and a fast text editor as Sublime Text.
• For MongoDB I have used Robo3, but I have seen there are better options that allow to drop/insert/edit objects from nested arrays easily for quick testing. For relational databases I felt comfortable using Toad with the appropriate driver.
• For SOAP web services I have used SOAP UI; postman and curl for REST services; and Graphiql for Graphql.
• To deploy web applications, I’ve used next servers on the different projects I have worked for: Apache HTTP, Tomcat, Jetty, WebLogic, JBoss, Glass Fish, WAS, Nginx, But I do like the serverless initiative, which might help more people getting involved on software development and might help us to accelerate SDLC and costs.
• I am familiar with Windows, Linux and Mac-OS operating systems, and I feel more comfortable with Linux-alike.

Responsibilities:

• Fullstack web developer in charge of the migration of slow PHP/MySQL MPA to fast NodeJS/MongoDB modularized SPA/MPA.
• Instant sorting and filtering of records.
• Geolocation queries for finding nearest providers per region.
• Service providers images and logos to S3 with AWS client.
• Securing application with hapi-auth-jwt2.
• SSR to fasten page load, SPA to improve end user experience.
• Fixing issues on plugins the owners themselves were not able to figure out.

Confidential

Java Backend Developer

Responsibilities:

• Re-engineered Consumer Registration java module to be more maintainable and less error-prone with an elegant State Machine model that was already available in the platform but wasn’t used for that module.
• I even used such State Machine of their own in a way they didn’t use before, by taking advantage of their inheritance and the Strategy OO Design Pattern to simplify and isolate the different flows of the same module depending not only on different banks’ rules, but also on their different points of contact consuming the module. Later on, I worked on several less interesting change requests implementations and bug fixing.
• I worked on their GMPP 3.4 version demo automated setup so they could easily install small versions on the product and reset them to demonstrate potential consumers its capabilities.
• Implemented hot-refreshable JMX/Spring beans settings tree that could be manipulated in-line with JBoss Jmx Console but looked far better with any standard JConsole.
• Re-factored the architecture of plug & play add-ons between standard Billing Addon interface and Custom Billing to be capable to transparently implement further business logic like printing information on CDRs that was not possible in original architecture. The need for transparently plug & play add-ons allowed the connector to be replaced by a new standard CDR logger that was going to be developed in Argentina some months later.
• SSO web service session client implementation.
• Implemented dynamic keywords - commands wiring with Spring IoC.
• I fixed Apache Axis 2 1.5.1 client to avoid out of the box defect that prevents HTTP clients to use more than 2 HTTP connections.

• I migrated Documentum and FileNet; then I documented and mentored people from other teams the way to do it.
