Background

About

I'm a Master of Computer Science with a passion for everything computing related, specially software development. I've worked mostly solo or with very small teams during my time as both undergraduate and graduate so I am used to wearing many hats when doing something. Although I'm willing to research anything needed to achieve my objectives, regardless of the area, my real passion lies within backend development, being that the part of development which makes me more comfortable. Nonetheless, given my background as a researcher, I'm generally very flexible when investigating new roles.

A Framework to Support the Development of Self-adaptive Service-oriented Mobile Applications , 30th International Conference on Software Engineering and Knowledge Engineering (SEKE)
Published on: Jul 01, 2018
This paper proposes a framework to support the development of Self-adaptive Services-oriented MobApps, i.e., mobile applications that use web services to fulfill their communication needs and would greatly benefit from supporting self-adaptive technologies to maintain their QoS level at runtime. To show the feasibility of this framework, a case study for a smart restaurant was conducted and briefly presented in the paper. The results of this study enabled our team to establish a positive perspective on the contribution of our framework to the research communities involved. It was presented in person during the 30th International Conference on Software Engineering and Knowledge Engineering (SEKE 2018), held at Hotel Pullman, San Francisco Bay, USA, from July 1 to July 3, 2018.
Developing Self-Adaptive Service-Oriented Mobile Applications: A Framework Based on Dynamic Deployment , International Journal of Software Engineering and Knowledge Engineering (IJSEKE)
Published on: Nov 01, 2018
Extended version of the paper presented at SEKE 2018. This was part of a special issue containing a more in-depth description of a small selection of papers presented during the event and, as such, this paper offers more details regarding the framework's characteristics such as the adaptation model implemented by the framework, the possible stages of a service during its lifecycle and a small set of attributes suggested to evaluate the QoS of a service.
A reference architecture to support the development of mobile applications based on self-adaptive services , Pervasive and Mobile Computing (PMC)
Published on: Jan 11, 2019
Evolution of the framework proposed during my master's degree, aimed at supporting not only web services implemented to be used with mobile devices, but web services in general. This paper presents more details regarding a reference architecture to support such framework.
Developing self-adaptive composed services: a framework based on dynamic deployment, QoS metrics and semantic information , Sao Paulo State University
Published on: May 27, 2020
Master thesis presented as part of the requirements to obtain a Master's degree in Computer Science. Written in portuguese (pt-BR).
A Self-protecting Approach for Service-oriented Mobile Applications , SciTePress
Published on: Apr 27, 2021
Paper presented on the 23rd International Conference on Enterprise Information Systems (ICEIS-2021) from which I'm one of the authors. This paper's main contribution is an approach based on MAPE-K (Monitor-Analyze-Plan-Execute over Knowledge) loop and machine learning techniques to ensure self-protecting features in MobApps, in particular, those based on services.
