• Scope Data science solution for the energy sector to detect regions where invoicing and revenues are not aligned for the company Light, with accuracy rates of more 71% Data from the regulator Aneel states that from 2017 and 2021, energy losses from the company grew from 37.2% to 54%. Besides the financial harm, the people that pay correctly are the one damaged financially due the others that don’t pay. Therefore, the main idea is to locate those low income regions on the State of Rio de Janeiro in order to create initiatives as an instrument to let people who did not pay, to start paying correctly.) • Data Science Development Python programming using packages such as NumPy, Pandas, Scikit Learn, SciPy • Microsoft Azure Azure DevOps • Database management Usage of SQL for queries Show less

Undergraduate Researcher

• Aug 2013 - Jul 2014

Undergraduate Researcher on project to develop an electric moped. As a student acting on this project, it gave me practical experience needed to increase professional skills as an aspiring engineer. In this project, we used a three-phase electrical motor with 2.96 hp and 220/380 V with shaft diameter 3/4'', key 3/16'', rotation of 1740 rpm (4 poles) and weight of 22 kg. The motor is supplied by 4 VRLA batteries with 12V each, the connection with the motor is given by 2 inverters.Key Responsibilities: • Liaising with my supervisor and mechanical technicians to determine the best mechanical parts of the vehicle.• Liaising with my supervisor and another electrical engineer student to determine the best way to implement the electrical motor.• Calculating torque using mechanical engineering concepts learned from the University.Key Highlights: ✔ Manufactured mechanical parts using machining and welding techniques.✔ Implemented the electric vehicle by adapting a bicycle.✔ Plotted the system's torque and power using computer programming.

Teaching Assistant

• Nov 2012 - Jul 2014

Firstly, I've taught vectorial calculus, important tool for some mechanical engineering applications. For example, fluid mechanics, strength of materials and control systems.Then, I started teaching modern physics, which involves quantum mechanics, atom elements and even semiconductors. It is fundamental for a better understanding of materials science, lasers, nuclear energy and photovoltaic energy.Finally, strength of materials, an area that provides mechanical engineers knowledge to design structures, beams and pressure vessels. Also, an understanding of plasticity of solid mechanics that is fundamental for manufacturing processes such as forming and casting.Key Responsibilities:• Providing support to students with the subject, reading and writing on an individual, class or small group basis.• Giving extra help to students with special needs.• Assisting with marking and correcting work.• Attending meetings and reviews.Key Highlights: ✔ Supported many students from four classes (with 35+ persons each) to learn the subject and pass on the exams, in some cases with high grades.✔ Assisted with marking and correcting work from four classes with 35+ persons each.
