Message

At Technisys / Galileo Financial Technologies, I led end-to-end quality assurance for core banking implementations for Banco Davivienda, JIC Bank, and Petersen Group. My work covered functional, integration, regression, UAT, and end-to-end testing across the SDLC.

For Petersen Group, I owned test planning and strategy for critical flows, translating requirements into test cases and scenarios. I also validated REST and SOAP APIs, batch processes, and Oracle database records, and coordinated UAT and intercell testing.

I built a Cypress API testing framework in JavaScript for the Restful-Booker REST API, with authenticated CRUD coverage and a GitHub Actions pipeline. I also developed a Playwright and TypeScript UI test suite and a full-stack banking application using React, Node.js, Express, and MongoDB.
