About Sergio

With 5 years of experience in quality assurance, I combine a solid foundation of Manual and Exploratory Testing with the implementation of automation strategies, especially focused on the Back-end and the core of applications. My approach is hybrid: I understand business logic through manual testing and seek efficiency through the automation of critical processes. I am a profile with great learning capacity, currently deepening my knowledge in modern Front-end frameworks to offer comprehensive coverage.

What do I bring to the team?
• API Experience: Mastery of Postman and automation with Karate DSL to validate Back-end logic, reducing manual testing time by 60%.
• Hybrid QA: Execution of rigorous manual testing and development of automation scripts with Selenium WebDriver and Java.
• Technical Analysis: Ability to delve into the 'core' of the app, understand integration errors, and report bugs with real technical context.
• Commitment to Quality: Rigor in test case documentation and defect lifecycle tracking.
I am looking for projects where I can contribute my Back-end experience while continuing to evolve my automation skills in real environments.

I manage Agile methodologies and am accustomed to tasks in 2-week Sprints.

Work methodology.- I work with a model focused on objectives and weekly deliveries, which allows me maximum concentration and efficiency.
- Availability for meetings from 18:00h or by agreed slots
- Constant feedback
- Ideal for teams looking for an autonomous QA who progresses independently.

For punctual collaborations or hourly support, my rate is €45/h Available for maintenance projects of test suites or quality audits in API/Backend
