Experience
Google Data Studio Reports
I worked on an initiative to generate HTML reports for management, and I ended up creating Google Data Studio reports, using different spreadsheets as data sources. I fed these data sources with information from TestRail and Jira via API to generate custom reports and created a Google site to embed all these reports, and finally directed everyone to this site.
Software QA Engineer AWS Products
At Micro Focus, I had the opportunity and the challenge to work on an AWS initiative to create several AWS base AMIs with an installation of several products; those AMIs were published, documented, and available for clients to use and create their EC2 instances using this AMIs as base image.
Software QA Engineer TAF
As a QA automation engineer, I created several modules for a test automation framework used by all projects in the company. Some modules I created were:
• PageObject Generator: A module in charge of getting web elements from a given page and then generating a new Java class with the web elements located on the page. So that it facilitates other colleagues to generate new PageObjects for their projects.
• FTP transfer: A module that creates communication between the testing execution machine and an FTP server and provides generic functions to transfer files.
