Available to hire
I’m Sebastián Andrés Cortés Ordóñez, a multidisciplinary professional combining software QA, API testing, and web development with game audio and music production. On the QA side, I create and execute test cases (manual, functional, regression, and smoke), validate REST APIs with Postman, report bugs clearly, and support continuous improvement within Agile teams. I also work with SQL/relational databases and frontend web basics (HTML/CSS/JavaScript) to better understand user journeys end-to-end.
On the creative side, I design and implement audio for interactive experiences—recording and processing voices, composing music that fits virtual scenarios, and collaborating to align narrative and audiovisual coherence. I’ve also produced corporate video/audio content and later expanded into music education, helping children and youth develop musical skills through structured, inclusive methodologies. I’m excited to contribute to teams where quality, problem-solving, and strong attention to user experience are key.
