Tracfone

Senior Java Developer / Senior IT Manager          March 2010 – Present

I worked in the middleware automation of the Tracfone/Net10 cellular number portability service using a custom J2EE services framework, Spring JDBC Template, factory pattern and other traditional Java Web Application development techniques.

I was then assigned as tech lead for a large scale project aimed to adopt Oracle SOA Suite as the first SOA implementation in the company. During this period we developed, from the ground up, the required infrastructure (Solaris/Weblogic), software artifacts (BPEL, OSB and SOAP) and governance process  (continuous integration, taxonomy, policies, etc…) to complete a successful delivery of the technical solution.

My next assignment was again as a tech lead for the next large scale project of the company. The project aimed to incorporate IBM Websphere Portal (AIX/Websphere) as the next generation web application framework for our flagship brand portal www.StraightTalk.com. In order to support front end Portlet functionality, we developed middle tier components using the template pattern, decorator, object pools, object caches, EJB SOAP Adapters and more.

During these engagements I used a broad range of technologies including, Java programming, Design Patterns, DataPower MPG and WSP, Oracle BPEL and OSB, LDAP Integration with TDS/TDI, Websphere Portal and WCM, Jython, XSLT, xQuery, jQuery, Spring MVC, Maven and others.

Oversee.Net (DBA Moniker Online Services – Moniker.com)

Senior Applications Architect / IT Manager          March 2003 – January 2010

Back in 2003 Moniker needed a solution to stay competitive in the emerging domain registrar market. Their system was based on a disparate set of applications, both proprietary and third party. After a comprehensive analysis of viable options, I decided to port their entire enterprise systems to a uniform Java solution. The migration took a team of four developers (myself included) one year to complete, but the end result allowed the company to go from two thousand accounts to over twenty thousand on the first year alone. Their product inventory grew from about eighty thousand domains to over one million. Within the first three years, Moniker became a top 5 registrar, and a leader in the domain name industry.

Moniker.com is now a leading company in the Domain Registration and Domain Aftermarket industry. Being a 100% Java shop, Moniker development teams make ample use of design patterns, open source Java frameworks such as Spring, Ibatis, Velocity, Struts, XFire (CTX) and others.

Over the past seven years I’ve developed many java applications for Moniker, ranging from front end Servlets and Jsps to midtier interface systems and backend services. During this time I’ve made extensive use of core and mainstream libraries and procedures, development methodologies and design patterns.

Most recently, I worked on the following projects:

Designed and developed Moniker’s EPP compliant Java based middleware interfaces to domain TLD vendors using multithreaded designs, connection pooling, client/server architectures. All these applications are easily expandable and configurable via database configuration records.

Developed Java based data escrow management systems for all 140+ Moniker registrars (channels). This application collects domain transactional data from a MS SQL database, encrypts it using GPG and uploads it to IronMountain’s servers using SFTP connections.

Developed a Java based “whois” query application server to capture and parse data “whois” data fields from over 200 different TLDs. This application is fully configurable via database records, and was published as a SOAP web service to make it available across enterprise applications.

Sony Music

Applications Architect - Consultant          August 2000 – March 2003

Sony Music Latin needed a custom made solution for content management and data consolidation for the several web portals they have across a multinational system.  In order to minimize costs they required the solution to make use of their existing infrastructure and operating platforms.

The solution I developed includes: a centralized repository of data, accessible to all the portals and content managers; two web portal wizards to generate and deploy ready-made web sites, which work based on “templates” and “themes” to provide localized look and feel as well as branding for the different artists and offices across their region; a centralized news subscription services, which can generate subscription information of visitors based on a number of parameters (country, preferences, etc…); a video channel to play the latest full length music video hits, which can be fully managed online and is integrated with the data repository; several other tools for data mining, promotion management, etc...

Some of the sites running on this system are:

http://www.sonymusic.com.ar

http://www.sonyrocks.com

http://www.rabanes.com

http://www.shakira.net

http://www.chayanne.net

 

By using this system Sony Music Latin was able to: reduce the workload for New Media personnel at the regional level; eliminate duplicate data and save on storage space and data transfers; create and deploy new artist and/or localized web portals by running easy to use wizards and templates; easily manage promotional information and visitor subscription data; have a broader view of their system and more accessibility to consolidated data for analysis and metrics.  The system is being deployed throughout the different countries and departments which form Sony Music Latin America (USA, Mexico, Colombia, Venezuela, Costa Rica, etc…)

The solutions created for Sony Music are based on Lotus Domino R5 running on Windows 2000 and Solaris platforms, RealSystem Server 8 for media streaming.  Software development was done using Java, Formula Language, LotusScript (a subset of Visual Basic) and JavaScript.

The committee was formed as part of the State Wide effort – lead by State Senator Ron Klein and the Governor’s IT Task Force - to create a “NAP” in downtown Miami.  A NAP is a public network exchange facility where Internet Service Providers (ISPs) and other information carriers can connect with one another in peering arrangements. The NAPs are a key component of the Internet backbone because the connections within them determine how traffic is routed.
