Alejandro Ortiz Trejos

I am a QA Software Engineer with over four years of hands-on experience testing web, database, API, and mobile applications across iOS and Android platforms. I hold the ISTQB Certified Tester Foundation Level (CTFL) and am completing a Bachelor's in Software Engineering at Cenfotec University.

At Greenslate I created and executed manual test cases that reduced post-release defects by 20%, performed API testing with Postman, tracked defects in Jira, documented in Confluence, led UAT sessions, and built basic data-driven automation using Selenium. As an SDET intern at OfficeSpace Software, I worked with Watir, Ruby on Rails and Cucumber to improve UI automation coverage and performed accessibility testing with Axe DevTools and WAVE.

I bring strong analytical and critical thinking, Agile-oriented problem-solving, adaptability, and resilience, and I am fluent in Spanish with advanced English (C1). I focus on delivering reliable, accessible software through disciplined testing and continuous improvement.
