My team was assigned to automate a process using end-to-end testing with Selenium on a web-based cheque batch system for a Canadian bank. The objective was to have control over postable and unpostable transactions. Additionally, this automation resulted in a 30% reduction in the hourly workload of the accounting department employees, allowing them to reinvest that time in data analysis and other activities. Additionally, I developed a Command Line Interface using Golang to automate processes on the IBM Mainframe 3270 system for extracting reports and daily routines with queries from databases, enabling users to reduce errors and save time. Functions: - Designed and executed test cases for postable and unpostable transactions. - Automated functional and regression tests using Selenium. - Developed scripts to improve Mainframe Tasks. - Genetated reports and living documentation for test results. - Collaborated with other teams to resolve issues. - Maintained high standards with continuous integration using Jenkins.

To my team was assigned the challenge of migrating the core banking system of a bank in Panamá, and we successfully preserved invaluable information collected over decades. We built an ETL: Extract, Transform, Load process to transfer data from a provider to another using batches. The process involved replicating massive data ingestion from multiple servers to ensure data integrity, including non-functional factors like security, scalability, and performance during data transfer. Finally, extensive reports and validations were conducted on the databases, and compatibility of the procedure was verified to minimize risks to the minimum. Functions: - Implemented ETL processes to handle large-scale data transfer and ensure integrity. - Conducted reports and data validations to verify compatibility and minimize risks. - Developed scripts to generate synthetic data before testing. - Ensured security, scalability, and performance during data transfer. - Developed test scripts for data integrity validation. - Automated report generation for continuous ETL documentation. - Collaborated with teams for effective communication and coordination.

I was assigned to perform functional testing on products of an insurance company. We increased the company's revenue by 15% annually with the introduction of a new service in the Colombian market called Seguro Peludo, which is an insurance for pets. We conducted extensive functional and performance testing throughout the development cycle, ensuring its production launch was a resounding success. Additionally, I automated a web service to facilitate the issuance of a mandatory insurance policy for road accidents in Colombia, and it was possible to reduce the regression testing cycle time from 2 weeks to 3 days. Functions: - Executed functional testing to ensure insurance products met business requirements and user expectations. - Executed performance and load testing with JMeter to handle high traffic and stress conditions. - Reduced regression testing time by automating tests and integrating them into the CI/CD pipeline. - Executed API testing and validated REST and Web services. - Generated test reports and documentation on testing status. - Supported end-to-end testing using Selenium to validate website functionality. - Collaborated with development teams to identify and resolve defects.
