About Rafael Costa

I work with the development, deployment, and architecture of AI solutions. My daily routine involves Generative AI (LLMs such as Llama and GPT), supervised and unsupervised learning, and the delivery of these models to end users through web applications with Frontend (React) and Backend (Python: FastAPI, Java: Spring Boot, and PostgreSQL).I have experience in Natural Language Processing (NLP), supervised learning, and unsupervised learning. I also participated in the development of articles and tools made available to the scientific community, integrating OpenAI Gym with RoboCup simulators for training agents in a simulated robot soccer field using reinforcement learning (Python, C++, and Java). (https://www.softwareimpacts.com/article/S2665-9638(22)00093-8/fulltext)I have also worked on projects including:Web applications with Chats using LLM (Llama 2 13B, Python, FastAPI).Web applications for text classification using AI models.Desktop applications for data collection, manipulation, and visualization from the internet: Selenium and PyQT5, Tkinter, Pandas.Web applications for managing Master's and PhD students for UFBA: MySQL, Python, React, FastAPI, Vercel, AWS, and SendGrid for email delivery.Web applications for communication between UNEB students: Java, Spring Boot, React, PostgreSQL.Web applications for assisting with color palettes (UI design): React.

The main focus of the project i'm working is the kick decision policy. To do that it was necessary to crate a proxy to collect data from the server which runs the simulation and also the criation of the environment to train the agents. Current work envolves training multi agent systems to enable cooperative behavior.Used technologies : Python, OpenAI Gym, C++.
