RocketPyAugust 2021 - Present

- RocketPy is the next-generation trajectory simulation solution for High-Power Rocketry. The code is written as a Python library and allows for a complete 6 degrees of freedom simulation of a rocket’s flight trajectory, including high fidelity variable mass effects as well as descent under parachutes. I participate in the PR&O team (Public Relations and Outreach) where my main activities are:
- Implementing CI practices
- Implementing acceptance tests, unit tests and others
- Outreach to new rocketry teams
- Outreach to competition to establish partnerships

Escola Politécnica da USPJanuary 2020 - August 2021

Developed research focused on autonomous ship seakeeping for Dynamic Positioning(DP) using Reinforcement Learning. Usually my tasks where:
- Reward shaping and environment design for Reinforcement Learning framework using DP knowledg
- Dealing with heavy computations for testing hypothesis and training new models
- Results discussion and Presentation for stakeholders
- Reading papers from both the DP community and the RL community to have new inspirations

The hardware, the experiments instrumentation and the physical simulator was provided by the TPN laboratory. Had a full scholarship provided by the FUSP foundation.

Why this research is relevant
- DP systems are overactuacted, therefore it's necessary to have a system that is able to evaluate across all possibilities of actions, RL is a great tool for solving this proble
- Developing new knowledge of RL sim2real
- RL still not diffused in the Naval engineering applications and specially in DP

Technologies used:
Matlab, Python, Ray, StableBaselines3.

This project aims to present the Prisba application. This application offers a serviceproduct search to purchase based on the customer's location according to his proximity to shops. Thus,the advantage of this application is to create a space where the prices of the product markets are seenby the community that can go either purchase the product directly at the store and share productinformation with other users. The project is being developed by students of Integrated TechnicianIFSP Informatics and has both the goal of putting into practice the programming concepts learned inthe classroom and motivate them and prepare them for the labor market thus reducing evasionstudents.
