February 2014 – April 2015 Globant Argentina Sears Holding Corporation ShopSears Backend Developer StarReviewers Software Designer ShopYourWay Shadow Architect As associate architect in the Sears Sweepstakes team (+25 members), worked on the architectural design and development of “New Awesome Tool”. The tool backend was developed using Spring 4 (Boot, Data Rest, IoC, AOP, Security), Hibernate 4, Jpa 2.1, Jersey 2.14, MySQl 5.6, Memcached, ActiveMq, Tomcat 8, AngularJs and NginX making. This project keys to success where performance, accuracy and ease of use. As part of my leadership role, I made sure all the technical constraints were met, assigning tasks to team members, unblocking complex technical issues and monitoring the team performance. I also worked on technical analysis of new features like Paypal API integration. New Awesome Tool is a web administration tool for end users to create custom promotions for ShopYourWay Sweepstakes, a massive rewards and promotions system. On “StarReviewers Project”, worked as software designer side by side with the team architect. The technology stack consisted on Spring 4(Boot, Hateoas, IoC, AOP, Security, Social), Hibernate 4, Jpa 2.0, MySQl 5.2, Memcached, ActiveMq, Tomcat 7 AngularJs with Bootstrap and NginX making where performance, gamification and systems interconnection was the key to success. I created a flow manager that connected a set of APIs like USPS, Fedex, UPS and DHL to validate addresses and track packages sent to customers. Designed from scratch a dynamic and fully automated rules engine with timers and email remainders. This engine UI included 4 a wizard for administration and allowed to create reports with a minimal knowledge of SQL using the embedded reporting engine. The web application was developed using social gamification technique to motivate customers to write reviews for Sears/Kmart products. I also participated on the screening process taking interviews for other Sears projects such as MyGarage, ShopSears over the course of my stay in Globant. MyGarage is a web tool to remind Sears customers about car services schedule. ShopSears is a mobile selling platform for Sears associates and subsidiaries. April 2013 – January 2014 Arena Software Argentina Pan American Silver IBM Maximo Customs Developer During this 10-month-project, I built java custom classes that modified Maximo’s purchasing module to comply with argentine economic legislation. After successful deployment to production, worked to setup Maximo interface with “Bejerman”, a non-compatible ERP for SMEs. To achieve this, I worked for 3 months with Bejerman’s consultant to develop an interface for interoperability that enabled PAS to successfully reconcile GL accounts between the systems involved. After this stage, I taught courses of development and deployment of Birt reports in Maximo. As a result of this, PAS development team started making their own reports. This was probably the most challenging project I’ve taken part in, because of the project’s nature and the magnitude of manipulated data, not only in terms of millions of records but also in money amount. April 2013 – February 2014 Arena Software Argentina Celulosa Argentina Software designer While attending PAS requirements, worked part-time for Celulosa Argentina, performing functional analysis and supporting the development and deployment of “Celucargas”. This web application sat on Spring 3 (MVC, IoC, AOP, Security), Hibernate 3, Jdbc, DB2, Tomcat 7 AS/400 with HTML5 + JQuery and Apache. The key challenge in this project was to modernize front & back end systems without performance loose while reutilizing current infrastructure stack with a minimal hardware addition. As a technical leader, with strong knowledge of legacy systems and infrastructure, I had to develop complex bash scripts to automate deployments and sync between heterogeneous software ecosystems. Celucargas is a mobile & web application tool for transportation assignments that let Celulosa, not only improve transportation offer and quality of service received but also reduce overall transportation costs. 5 Litoral Gas (GDF Suez) January 2000 – March 2013 Argentina GDF Suez Oracle & Java Analyst / Developer. Maximo EAM 6.2 Analyst / Developer. As an Oracle analyst worked in a team of +10 members, not including third party members. Worked on development and maintenance of “SIC-LG” and development of generic fleet cost management software. The mentioned win32 applications were developed using Oracle Designer 10g with Oracle Forms, Oracle Reports, and bash scripts making where scalability was core to serve requests consuming data from DBs containing several millions of records. The solution included utilization of PL/SQL stored procedures executed from concurrent daemon processes to support billing, purchasing, and interoperation with SCM, CRM and Oracle Financials among other interconnected systems. “SIC-LG” is an Oracle utilities based ERP with an extra layer of business logic to meet argentine legislation for LNG distribution companies. As Maximo product manager I successfully deployed Maximo 5.2 in Litoral Gas. At that time, I was responsible of the coordination of an external team composed of 6 developers from “Solex” (IBM Maximo certified partner). Two years after going live, I profitably managed the migration to Maximo 6.2 with an external team of 5 developers from “Tecso”, we run on budget and met deadlines as planned. The outlined projects where tracked using tools provided by IBM, closely following the guidelines from “Maximo Development and Deployment Blue prints”. March 1999 – May 1999 Digital Word Argentina Hospital Italiano Software Analyst During this 3-month-project I worked as system analyst and helped the sales team with project effort estimates and high level designs for the RFQ response for a public bidding. Digital Word did not win the bid, but the lessons learned were huge and all the team acquired knowledge about hospital management. November 1998 – October 1999 Digital Word Argentina John Deere Software Analyst / Developer In the course of this project I worked as analyst and developer for John Deere’s Mutual fund. My number one responsibility was to analyze reporting requirements, build complex queries and stored procedures, design reports and publish them in the fund’s management 6 system. The key to success in this project was normalization and report tuning, because fund’s system was overloaded and the DB table structure was not normalized, as a result of this, queries took a long time to run and vertical escalation did not pay in gold. The Mutual Fund management system was a legacy system built on Ms Visual C++, Ms Sql Server DBs and Crystal Reports. November 1997 – October 1998 Enfoque Ingeniería Argentina Magret, Mackey, Finlar Software Analyst / Developer All along these projects I worked on architecture and development of “Orion”. This ERP was developed using Obsydian (a CASE tool, nowadays is named CoolPlex), Sybase SQL, C++ and Crystal Reports. At that point in time, portability was core to let us deploy Orion on any OS environment and choosing Java, C++, or another supported language of convenience was a clear differentiator from competence. As part of my role, I made sure every release run without problems in the selected environments and release dates could be met. I also instructed other team members on techniques to make effective deployments on clients. The system was profitably deployed on Magret, a manufacturing company that produces vacuum packed pork meat for the Argentine market. After first successful deployment of Orion ERP, leading a team of four analysts, Orion’s was successfully deployed on McKey and Finlar. McKey (Keystone Foods LLC) is a food production company that served McDonald’s operations. They implemented Orion to manage its packing plant in Buenos Aires. Finlar is a meat manufacturing company based in Argentina, that bought Orion to manage its slaughter plant production.
