Engage with React Nanodegree students and provide them with actionable and personalized feedback on their projects to help them progress through their Nanodegree program. Through guidance via in-depth code reviews, project evaluations, and 1:1 sessions, continued student success is ensured.

Worked migrating the Feedback Loop visualisation to React and then developed new functionalities for it.

I worked mainly with front-end development, using React/redux, leaflet, to create interactive maps and data visualizations to help public prosecutors to fight for public claims with data, specially in political processes. Everything we developed here was open source and with open access, so every citizen can have the access to the same platforms.

I worked on the project "Map of Civil Society Organizations". This project aims to improve transparency on the relationships formed by the Brazilian government and NGOs. To develop this solution the project started using Java and GWT, but we migrated to a development with node.js on the back-end and Javascript (React), HTML, CSS on the front-end. To plot the map we use Leaflet and to create charts and visualization, we use D3.js.

Improving business processes management for startups and micro small and medium enterprises.

I taught Front-end development for an undergraduate class. The course encompassed: - the basic concept of client-server architecture - HTML5 syntax, elements, DOM and the render tree concepts - CSS3 syntax, attributes, selectors - Javascript syntax, programming logic, main methods and attributes - JQuery syntax, selectors and logic - Responsive Web Design concepts and best practices

My activities included researching and providing solutions to interface design, data visualization and the back-end part of research applications. While working at IBM I used the following technologies: Java, J2EE, Spring, Tomcat, IBM Websphere, Javascript, Dojo.js, D3.js, Python.

I taught undergraduate classes, object oriented programming using Python. The course encompassed: - OO Programming concepts and logic - Exception treatment - TkInter module

I worked developing systems for production and exploration at Petrobras, using Java, Hibernate, Oracle and Javascript, JQuery, HTML, CSS.

As a researcher and developer, I worked closely with both schools of Communication from Federal University of Espirito Santo and Federal University of Rio de Janeiro to conceive, plan and develop social network analysis from tweets of social events. The technologies used in this project were: Python, Gephi, Social Network Analysis, Social Network Visualization.

Analyze processes handled by Brazilian Supreme Court. In this project, we used Python to make a crawler in order to get the data from the Supreme Court website, stored it into a MongoDB database to create visualizations using D3.js.

Development of scripts to generate automatic reports about process models and the development of scripts to generate automatic changes in process models. It also included activities such as: web publication of process models, development of new libraries, research of new functionalities and solutions for extracting information contained in the process models. While working at Montreal I used and learned the following technologies:ARIS Script, ARIS EPC Notation, BPM

I worked developing systems for production and exploration at Petrobras, using Java, Hibernate, Oracle and Javascript, JQuery, HTML, CSS.

I worked within a mentor team, helping systems analysts at Petrobras in activities that involved the preparation of system requirements specification documents. I also worked as instructor in system analysis classes for the company.

Studied the use of visualizations to increase understanding in political discussions.
