I’m a frontend-focused full stack engineer based in Guayaquil, Ecuador, with deep hands-on experience building enterprise digital banking experiences. I work primarily with React and Angular to deliver reusable Design System components, microsites, webviews, and microfrontend-style architectures, with an emphasis on clean, modular code and event-driven communication across onboarding journeys. On the backend/integration side, I connect frontend applications to REST APIs using Node.js and Java/Spring services, and I’ve worked across CI/CD, testing, and quality gates (including Jest/React Testing Library and SonarQube). I also enjoy modern engineering workflows supported by AI—using LLM-assisted development, prompt engineering, tool/function calling, and exploring RAG and MCP concepts to help automate and improve day-to-day delivery.…I’m a frontend-focused full stack engineer based in Guayaquil, Ecuador, with deep hands-on experience building enterprise digital banking experiences.
