- Manuela Cortés Granados's CV
At Informatica y Buen Gobierno, I led backend, frontend, and automation testing efforts for a suite of highly visible, high-traffic public sector applications serving thousands of concurrent users in real-time. As a Java Software Developer and Senior Front-End React Developer, I built scalable React and Next.js interfaces, optimized with Webpack and SSR for performance under load, while integrating RESTful and GraphQL APIs for efficient, flexible data access. I engineered real-time, cross-platform mobile experiences with React Native and implemented performance-first architectures with lazy loading, CDN caching, and modular code splitting to support high concurrency and responsive UX across web and mobile. On the backend, I collaborated with distributed teams to ensure robust API design and low-latency response handling, using Java and Node.js services. In parallel, as a Senior Automation Test Engineer, I designed automated frameworks in Java and Python for end-to-end, unit, integration, and mobile testing, using Selenium, Appium, Cucumber, and Jenkins pipelines, enabling early detection of regressions across platforms. I implemented continuous testing for government-grade CI/CD workflows using Jenkins, GitLab CI, and Travis CI. These applications were subjected to intense public use and scrutiny, often handling tens of thousands of users during critical service periods, requiring careful resource planning, async communication, performance profiling, and resilient architecture. While I haven’t worked directly on a game, my experience building systems under real-world high-traffic stress — including national-scale web services with strict performance SLAs — has prepared me to solve backend challenges at scale, exactly as your role requires.
