Empirical Studies on the Software Testing Profession

Data Scientist, Co-author, [Jan - Jun 2016]

Stakeholders: 

Luiz Fernando Capretz, PhD (Faculty of Electrical and Software Engineering @WesternU)

Funding: 

Emerging Leaders of the Americas Program

This empirical and global study analyses the causes of the unpopularity of the tester role in the software industry in Cuba, Canada, India and China. Our goal is to spark debate about the human dimensions of the testing activity looking for motivating/demotivating factors for software practitioners to take up and sustain testing careers.

Participating in this project allowed me to train myself on how to conduct empirical research methods, how to interpret a comprehensive approach to study a given phenomenon, how effective networking and collaboration are in science, and how to apply research in real industry scenarios.

Partnerships with Faculty of Education, @WesternU

Data Scientist, Co-Author, [May 2018 - May 2019]

Stakeholders: 

Melody Viczko, PhD ( Faculty of Education, Western University), Cultureplex Lab

Funding: 

Western Strategic Support for SSHRC Success Seed

This collaboration with Professor Investigator Melody Viczko, allowed me to apply my knowledge of digital methods in a different research area as International Education Policy. We developed two research projects: Mapping global actors in Higher Education trough their Twitter activity, and Assessing the response of Higher Education Institutions to the #WelcomeRefugees initiative launched by the government of Canada to receive Syrian refugees in 2015.

I analyzed the co-mentions, co-hashtag networks of 1.25 million tweets around 2015 and 2016,  and applied Natural Language Processing to understand the topics of debate in the public sphere.

Chronos: Asynchronous Replication Tool for PostgreSQL

Co-founder, Software Developer, Analyst, [Sept 2009 - Jan 2011]

Stakeholders: 

Universidad de las Ciencias Informáticas

This project taught me to surround myself with people who pushed me to my limits helping to lay the foundation for my software-engineering career. I’m grateful for the time I spent with the team that gave me a glimpse into the challenges and rewards of a startup employee’s life. I develop, maintain and deploy the asynchronous multithreaded core application that guaranteed the data replication in real-time for PostgreSQL. I fell in love with open source coding philosophy and start thinking about the impact of ethics, privacy and transparency in my research.
