  I was in charge of a portfolio of 07 to 08 projects with around 90 professionals. These projects included interoperability, ship monitoring (LRIT, VMS, fishing and rivers), support to the decision-making process, and business intelligence.I was responsible for supervising the management and technical solutions for the projects under my portfolio, including budgets approval. Also, I handled interpersonal conflicts and contacts with clients and other actors to solve disputes when needed.As Head of Division, I participated in all selection processes, considering the candidates' technical knowledge and evaluating their suitability to the organizational culture.In parallel, I was one of the leading researchers in the organization. Some achievements: - Responsible for implementing the initiatives to incorporate Business Intelligence and Data Science concepts for current and new projects.- During 2015, I have participated in a working group to discuss and suggest a solution to the enterprise services architecture in the Brazilian Navy. - As a technical advisor to Brazilian delegation in IMO and Inmarsat meetings, I have suggested and drafted Brazilian submissions to IMO for LRIT and related issues (e.g. ship reporting systems). In 2016 I performed the Brazilian role in a testbed with Singapore and Norway. This testbed has originated internal research about maritime single-windows interoperability.- I led the project to design a solution for tracking the water traffic in the Amazon basin, with more than 8,000km. The solution included amendments in regulation and the architecture for collecting, analysing and summarising the data, in a distributes architecture.- Following an invitation, I presented in an IMSO international symposium held on the International Maritime Organization (UN agency) the data analysis from 10 yeas of merchant ships positional data and search and rescue operations around all the world. A similar analysis supported policy decisions in Brazil.

• Project Manager

  • May 2017 - Mar 2018

  The BI-Corp was a pilot project for implementing a data warehouse and business intelligence infrastructure (using Kimball methodology).The team had 4 PhD, 2 MSc and 2 analysts, with expertise in data science, business intelligence, statistics, operational research, software engineering and domain knowledge.An initial infrastructure was put in place with the Pentaho suite and ETL solution, and the Saiku for online data visualization. Experimental analysis was done in R (RStudio). An instance of PostgreSQL was used for the data warehouse and the datamart. Once the infrastructure was ready, the client indicated the processes to be initially monitored, together with the metrics. The ETL pipelines were designed and the data was stored in a dimensional model (star model).I left the organization and the project at this stage.

• Head of the Department of Systems Engineering (Interim)

Even so, I informally supervised the project and the system architecture remotely. In March 2015, after returning to the research centre, I was again designated as the LRIT Project Manager. I remained in this position for six months while training my substitute. I stayed as a technical supervisor for the LRIT and until 2018, representing Brazil in UN-related technical meetings due to my expertise and background in architecture the business rules.The LRIT Brazilian RDC is developed using JEE specifications, using the PostgreSQL database and GIS support from PostGIS. The software uses SOAP/XML 2.0 web services over TLS 1.2, and the XSD specification is provided in the IMO technical documentation. The deployment environment consists of Glassfish AS on Oracle Linux, running on a cluster of VMWare virtual machines.During this period, we updated the billing system, which concepts are slightly similar to the telecommunications billing – based on messages types.

These projects involved around 10 researchers.Some of the outcomes are: a study for spatiotemporal data fusion where the positional information has different levels of uncertainty, simulations, participation in international forums to improve the global specification for the LRIT. Under this project, I participate in several international forums as Brazil representative or adviser, and I went to Namibia, Peru, Uruguay, Cape Verde to provide training and to negotiate their participation in the system.

• Technical leader - Long-Range Identification and Tracking of Ships (LRIT)

  • Feb 2008 - Nov 2008

  The LRIT is a system designed by the International Maritime Organization (IMO). The Brazilian project implemented the data centre to track Brazilian merchant ships through satellite. I started as deputy manager and technical leader, in charge of architectural decisions on the GIS database (Postgres+PostGIS), refining the requirements, test plan and component architecture (JEE5 + JBoss).The system was to be deployed in a cluster and to provide 99.9% of availability.The outputs from our project were discussed at IMO and influenced the global architecture of the LRIT. This was the first distributed system with GIS support in Java developed in the research centre. I enforced some innovations in testing, such as unit and system automated testing, cluster deployment, use of simulators for performance testing.I was part of the expert Grupo that draft the global system, and I participate in this task until 2017.
