Worked at two projects, first one to BrasilTelecom, a telephone company responsible by wired clients over regions center-west, north and south in Brasil, contracted Neoris as one of the role players to create the infrastructure for their VOIP (Voice over IP) environment together with Lucent and Alcatel. Neoris was responsible to create and manage the instant message system of platform and customization of VOIP customer desktop application based in Xten API. The product known as VoipFone BrT was delivered to public at the end of 2005 the responsibilities was design, develop and deploy of the IM system and contact list in the server-side, using Apache under Linux as base and creation of a middleware at Oracle9iAS Application Server written in Java, also responsible for customizing the client softphone written in C++ based on technology from Xten (Eyebeam softphone) in MacOSX, Linux and MS Windows. Using tools like MS Visual Studio, gdb, shell script, codeviz, doxygen, wireshark, rational rose, etc The second project Neoris do Brasil was assigned to develop a new Media Planning system for British American Tobacco do Brasil (a.k.a. Souza Cruz) (being part as extension of their e-Business system). BAT requested that system would have to create media ads scenarios achieving the best relation between of their media implementation costs (minimizing) and marketing share of voice (maximizing) through pre-configured brands ads scenarios set along certainly time periods and based in marketing and economic data metrics of customers, outlets and brands, this system was designed to have an dynamic optimization core to deliver those results. BAT's new media group area was responsible for the requirements and budget of project and tagged the system an extremely necessary and innovative media decision tool for them. Actually the system is a decision-making tool to help media managers to simulate and create marketing scenarios for their ads in an restrictive tobacco law environme

Telemar/OI a telephone company located at Rio de Janeiro and is the greatest telephone company in Brasil. They required to create a new public message telephone system for their wired clients for such they hired ADG Systems to create a dedicated group responsible to delivery this new system as soon as possible. The new system was based in their production system at that time that was running in MS Windows NT 4. The new system was conceived to be run in a Linux environment in order to reduce the related costs of licenses and maintenance and to be more scalable than the original system, the scalability was achieved using CORBA technology at all. The system was projected to be capable to receive a huge amount of calls at same time in available hardware as well as to delivery a strong amount of calls for their direct media ads. The system was installed in all digital network telephony broker of all cover regions, totalizing more than two thousand installations running at 24x7 schema and high-availability architecture. Responsibilities: Design and implementation of the core architecture in distributed, redundant, high availability schema. Develop using C++ programming all modeled based in Design Patterns and Object Request Broker CORBA architecture (using c++ framework ACE/TAO), Qt GUI API for the graphic user interface of management application and with Firebird database (with real-time and memory db extension enabled) all running under Linux system. Also involved in the formulation of new IVR (Interactive voice response) with Linux using Dialogic telephony board. Common tools for design, profiling, debug and test were: KDevelop, umbrella uml designer, gdb, vi, Valgrind, creation of many helpfull shell script, source-navigator, codeviz, tora, wireshark, HeartBeat-HAL (High Availability Linux) tool and CVS as control source version.

Description : UOL is a bigger internet content and service provider in Brazil, UOL product manager team was required to create a system to improve the navigation performance and the perceived presentation experience of web sites accessed by their subscribers dial-up clients (all them limited by download band of 56Kb/s) for such the network and infrastructure teams purposed to assembly a set of grid systems acting as a transparent network element that were responsible to re encoding all texts and images of those clients in order to reduce the size of these HTML elements applying coherent heuristics as desired by each client, like per example the reduction of color space in the images. The system was conceived to be a loading balance grid where each element in system is a modify Linux version (within proxy reverse schema at kernel) with Apache web server that contains modules created to apply those codifications and the digital image processing implemented internally at UOL based in information delivered by web-browser client through new UOL toolbars extension as a set of specifically HTML header. Responsibilities: Design, conception and development in C/C++ programming of the server-side application of solution many running as modules in Apache (using c/c++ APR API to create them) and for Firefox web browser toolbar as multi platform client side (using XPCOM architecture and XML RDF schemas). Implementation of data compression methods and necessary algorithms and heuristics in text and digital image processing of supported HTML images types: JPG, GIF, PNG and TIFF in the new Apache modules. Extensively use of the development linux open source tools for profiling, debug and unit and performance test like shell script to create tools to help in performance and unit tests, dia for UML design, KDevelop, gdb, source-navigator, cscope, doxygen, perl, valgrind and the Rational ClearCase/ClearQuest package was used as control source version and bug track manageme
