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.

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.

undergraduate courses:Information security, Software Engineering, Software analysis with Object-Oriented Paradigm and UML, Dara structures and introduction to JEE, Artificial Intelligence, Electric materials.graduate courses:Design patterns and Frameworks, Software Architecture, Information Security - Strategic Planning, Analysis and Design for Object-Oriented systems.I had a break in 2014 and 2015 because of the post-doctorate abroad.

Interim position.The Department of Systems Engineering encompasses seven divisions, including R&D, and the Project Management Office (PMO). Approximately 200 collaborators and 30 projects were under the department. I took over the department as the senior officer in the divisions, awaiting the arrival of the newly appointed Head of Department.It was a difficult period since the Research Center was suffering a downsizing because of funding reductions. The senior officers, under my guidance, were required to decide on the teams' cut and how to avoid losing invaluable knowledge on the systems and know-how.

After returning from my post-PhD research period, I was selected to take over the strategic systems division. I was posted as Deputy Head of Division for 08 months for training, while I was simultaneously in charge of a project (LRIT) and training the new manager for the project.As a deputy head of the division, I mostly take over the bureaucracy associated with the role, seeking the head approval for the important decisions under his responsibility.

Manager and software architect of the project LRIT Brazilian Regional Data Centre. This system track merchant fleets from Brazil, Namibia and Uruguay.I have managed this project from 2008 to 2013, with one year of interruption due to my post-PhD abroad in 2014. 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.

I worked in the Agents and Intelligent Systems Group, Department of Informatics. The lab team was a multicultural and multinational group. My research theme was related to interoperability. I have used MASON framework, in Java technology, to test a heuristic algorithm to tame tardiness in distributed simulations by collecting performance metrics and intervening at run-time.My research theme was the virtual simulation interoperability. The research depended on statistical analyses for its evaluation, using hypotheses testing for the models (GLM and ANOVA). I used R for the data analyses.

Lecturer in Computer Science. I gave classes on Algorithms, Object-Oriented Programming (with Java), Software Engineering, and Computer Architecture.

I was designated for working at the research centre just after my MSc, and during this period I conclude my PhD in part-time and a graduate curse for management level. I left the research centre in 2014 to conduct post-PhD research and returned after.As a researcher I was in charge of implement best practices in the centre, bringing the projects to the state-of -art. I led and participated in initiatives for:implementing change control and version control disciplines, using Subversion;• normalizing the development environment (eclipse on Linux)• starting automatic builds (Ivy + Ant) and after implementing continuous integration (Maven, Jenkings, testlink, Redmine, automated unit and integration tests)• implementing formal software development processes (both CMMI and Scrum based)• Implementing concepts of data warehouse in a project for the first time in the organization.As a project manager, I was in charge of contract management. I was responsible defining scope, budget and schedule with clients, and after this proposal agreed, I would draft the contract with detailed information. Managers also sign the contracts as technical responsible for the execution and are the contact point for client issues. This is part of the formal process defined in the research centre for project management, from the inception to the final report. The process was based on PMBOK (PMP). I was required to select and interview candidates for the projects and forming the teams.

SADLOG is a decision support system for logistics, originally programmed in PHP.This was an architectural refactoring project. The software was redesigned and implemented in Java EE, incorporating the old and new requirements. The new database uses star-model as a data warehouse, to allow recovering dimensional data (OLAP cubes). The new architecture allows for automatically collecting information.Project team: 7 professionals.

• Manager and software architect of the project LRIT Brazilian Regional Data Centre. This system track merchant fleets from Brazil, Namibia and Uruguay. During this period the system was updated several times to improve its performance, usability, security and to offer it under Software as Service (SaaS) to other countries. The LRIT Brazilian RDC is developed using JEE specifications, deployed on JBoss EAP, using 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.

CERDAIM stands by Regional centre for maritime information and tracking, and MAZFM is the Monitoring system for the blue amazon (south Atlantic east ocean) and national merchant fleet. Both were research projects associated with the LRIT project scope, granted by FINEP and the public fund for water transport and shipyard. 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.

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.

In 2013, I concluded my PhD course with a multidisciplinary thesis, in which I used R and statistical experiments and analysis. These tasks included generalised linear models, ANOVA experiments for multi-dimensional data, principal component analysis, and others. The reports were automated using Gnuplot, Latex and R.The results of this research were presented in seven symposiums in Brazil, United States and Italy.
