Galo Sebastián Sánchez Montero 👋

Senior QA Architect with 5 years designing performance and test automation strategies across APIs/web services, web applications and public websites, mobile apps (iOS/Android), and SaaS platforms—primarily within financial and enterprise environments. I focus on performance engineering and scalable automation to help teams ship reliable software faster and with less risk. I build test architectures with K6, Karate DSL (Java), Serenity BDD (Java), Playwright (JS) and Selenium (Python/Java); integrate suites into Azure DevOps CI/CD with quality gates and parallel execution; and partner with Dev, SRE and Product to improve reliability, observability and delivery across the SDLC. Recent outcomes: shorter regression cycles, improved P95 latency at scale, earlier defect detection; mentored junior QA on best practices and framework implementation (Karate/Serenity/Playwright); and delivered internal trainings on services/API automation with Karate DSL and quality gates. Core stack: Performance Testing (K6), API & Microservices Testing, Karate DSL, Serenity BDD, Playwright, Selenium, Postman, SQL databases & MongoDB, Salesforce, Azure DevOps CI/CD, Git, Observability.
