About Brian

I am a QA Engineer with more than 4 years of experience in software quality assurance, specializing in Manual Testing, Test Automation, and API Validation.

I have participated in projects of different scales working under agile methodologies, collaborating with development teams, functional analysts, and Product Owners to ensure product quality from the initial stages to its production release.

My experience includes designing and executing test cases, functional testing, Smoke, Regression, and End-to-End testing, automating web interfaces with Java and Selenium, validating REST services using Postman, Swagger, and SoapUI, as well as performance testing using JMeter.

I focus on identifying defects early, optimizing Testing processes, and providing solutions that improve application stability and reliability. I consider myself an analytical, organized, and detail-oriented person, with the ability to adapt to new projects and technologies.

I am available to collaborate on Manual QA, Automation, Performance Testing, and API Testing projects, always with the goal of delivering high-quality software and generating value for the client.
