About Me
Assistant Professor (Tenured) at the State University of Ceara (UECE). Software Engineer and Computer Scientist. I received my PhD degree from University College London, where I was supervised by Prof. Mark Harman and Dr Jens Krinke.
My research interests revolve around software and repositories analysis. I find software engineering data fascinating due to its complexity, lack of structure and mix of technical and social aspects. My recent publications involve microservices, software architecture, software refactoring, modern code review, and mining software repositories. Search based software engineering has been my introduction to academia and it is a topic I cannot keep myself away from.

Teaching
Mining Software Repositories
This is a course I created as part of my teaching activities as a research assistant at UECE. This is a research-intensive course targeted at Master's and PhD students in software engineering. During the course, the students were exposed to a wide range of MSR-related topics, ranging from the basic building blocks of MSR research to the step-by-step process of conducting a MSR research project to presentations of recently published state-of-the-art papers.
DevOps, Tools and Automation
This is a course I created as part of my teaching activities as a research assistant at UECE. This course is targeted at Undergraduate, Master's and PhD students in software engineering. During the course, the students are exposed to DevOps concepts, ranging from social to technical aspects. In addition, I teach and discuss the main activities in the software development lifecycle that are commonly automated. Finally, I present a set of state-of-practice and state-of-the-art tools to assist in automation.
