Design, implementation and installation of an autonomous, portable and customized dashboard platform for the client Atap Surya Nusantara to provide data-visualization for one of their solar panels VIP customers – Bank Danamon Indonesia. The solution runs on a PC stick, collecting all necessary technical information from the administration interface of the solar panels via REST API, storing it in a compact and temporary database. The front-end uses React.js, the data management, Python and SQLite in agile development methodologies, running in Linux Mint to keep the requirements of limited resources of a portable device.Design of a more sophisticated expansion of the previous solution to provide a platform to administrate data-visualization for not only different VIP customers, but also internal departments, each of them with their own customizations to fulfill the expectations of each user. The system will run in a cloud architecture, gathering data from distinct sources and types.Viability analysis and design for various monitoring systems using IoT mesh networking solutions to overcome Indonesia's challenging and complex archipelago infra-structure. Data management (preparation, integration and analysis) associated with Artificial Inteligence models Design and implementation of a cloud-based productivity suite that provides various tools for communication, collaboration, and productivity for the client Deka Wilma Advisory.

Expert Core Network Consultant for Nokia's customer Indosat Ooredo Hutchinson, focusing on crisis mitigation with long-term solutions for various IP elements in the network. During these years, we improved network performance and stability by following telecoms best practices. Comprehensive route cause analysis, technical solutions, preventive actions, reports, and analytics were presented to a highly qualified audience of managers and technicians on a wide range of topics relating to business subscribers, IMS (IP Multimedia Subsystem) network, 4G/LTE, and international gateways. During critical dates and situations where traffic tests the network's stability, the entire system was under monitoring in real time.Working directly with Sales, System Architect Teams, and Delivery Project Managers on proposals, planning, and execution, assisting them in deepening the technical analysis with details combining customer requests and the features and constraints of the platforms involved in the solution. As a result, this effort reduced the risks of an upgrade or the inclusion of new elements in the live network while adhering to tight deadlines.

Worked on Customer Service activities in platforms such as IMS, MBB (Mobile Broadband) packet core, and fixed network around the world; clouding and core virtualization studies using VMware-based VSP (Virtual Server Platform) architecture and applied to Packet Core, IMS, and OSS (Operation Support Systems).Setup, integration, and troubleshooting of a CSCF (Call Session Control Function) in their various roles - Proxy, Serving, and Interrogating CSCF over IPv4 and IPv6 in multi-vendor VoLTE test scenarios (Ericsson, Huawei, Nokia, Samsung) for the Mexico-based customer America Movil, providing, in addition, assessment KPIs for project follow-up in each of the rounds.Bring up, integration, and troubleshooting of HSS (Home Subscriber Server) for a sensitive swap for the client Algar Telecom.Setup, integration, and troubleshooting of Flexi NS (SGSN - Serving GPRS Support Node) and Flexi NG (Serving Gateway/Packed Data Network Gateway) platforms in ATCA (Advanced Telecom Computing Architecture) hardware with eNB (Evolved Node B) in a 4G LTE mobile packet core Nokia lab for internal job training, trials, customer service training, and offline fault analysis.I was solely responsible for the installation, integration, and acceptance testing of the entire NGN (Next Generation Network) with multiple elements for the client MTN Nigeria.Worked end-to-end with the Fixed Network Development Team in Greece on the translation of Argentinean Standards, embedded software coding, system verification, and handover to the local team for service acceptance.

Technical coordination for NGN embedded systems, involving projects for several customers in different countries, including Angola, Argentina, Brazil, Chile, Colombia, Mexico, Peru and Venezuela.Viability and estimating analysis of technical solutions for required features with call processing, protocol and signaling impact, PSTN or convergence network, intelligent platforms and specific features for subscribers and operators.System verification, diagnostic tests and quality assurance of access and media gateways, softswitches and media servers in accordance to the project specific requirement and country-related regulations. Outlined test methodologies and established test plan.

Responsible for IT infra-structure of a new office in Recife – MS imaging deployment of the user hosts; configuration of MS Exchange for corporate email; Cyber-security (automatic deployment and update of antivirus on the user hosts; proxy configuration).NGN projects development (analysis, coding, testing, maintenance) of soft-switch signaling/call processing related features, including trunk or subscriber adaptations.PBX billing call control interface application development in Java and CORBA.
