I've worked on different projects in education, health research, psychometrics, R package development. I contributed to the Brazilian 2020 Census for three months in planning the data collection, and I'm currently working at UFRN as a Statistician in Quality Management. It's been very fulfilling. Some key-words of what I do: SQL, Python, R, Markdown, Shiny, SCRUM (Agile)... MCMC, new statistical ideas in computation, the new trends of Big Data and good old classics (Regression Analysis, Exploratory Data Analysis, Multivariate Analysis, k-Means) are in my Repertoir. I hope we have a mutually beneficial relation!

He takes the time to understand the problem, comes up with different technical solutions for it and is communicative throughout the process. He provided an end R code that was very descriptive and wrote comments so that I could easily understand it. Not only this but Gustavo went above and beyond to make sure I understand the code by throwing in a live session where he walked me through each line of the code he had written. 10/10, will be asking all my coding questions to him!" ✔️ Exploratory Data Analysis - September 2022 ⭐⭐⭐⭐⭐ "Gustavo is one of the best tutors I ever had! He makes sure you understand and know what to do. He takes his time with you and walks you through everything. I appreciate his hard work!!" ✔️ Debug R Shiny App - July 2022 ⭐⭐⭐⭐⭐ "Excellent methodology and great at debugging.

Machine learning, mathematical modeling, and data analysis are the core of my skills. I can use existing techniques of diverse environments and easily adapt to different environments and frameworks. I can use these techniques in a wide range of applications, which include: radar image processing (SAR images), face recognition, natural language processing, marketing problems via GAMLSS, and remote sensing in Medicine (I took part in an awarded publication on this subject). Usually, I will ask you to describe your problem and your desired method of solution, if there is one. I can provide novel solutions that the client might not be aware of, and I usually bring this up during meetings and briefings if convenient. When not working in a team, I am very comfortable being the one to translate the practical situation to the mathematical setting and then present my solution, so feel free to contact me if all you got is a problem without a hint about the solution. I also enjoy very much discussing the solution with the client. Timely communication is important since I work a particularly demanding job as a teacher/researcher. It is very important to let you know that I am only available outside my daily work hours, which go from 08:00 to 17:00 (GMT-3 timezone) and weekends.

Software engineer with solid experience in building Cloud architectures and applications. Highly motivated by solving complex problems, engaging in research and development (R&D) activities, and possessing great leadership skills for development teams. Currently, focus on Backend development and architectural design, implementing microservices and APIs in Node.js, Java with Spring Boot, and Python. Dedicating part of the time to DevOps activities, I deploy infrastructures using CloudFormation (IaC), scripts in Shell/Python, create CI/CD pipelines, and automate code and architecture analysis. With a keen interest in artificial intelligence and statistics, I have applied its concepts in projects such as skin disease classification through image analysis using CNN (Convolutional Neural Network), sentiment analysis of texts using RNN (Recurrent Neural Network), mapping dependencies of one or more projects in dependency graphs, and creating species distribution maps using one or more Machine Learning algorithms.
