I build scalable fintech web and mobile products with React, Node.js, and AWS.
EcuadorWhat I'm looking for
I build secure, scalable web and mobile products for fintech and core banking environments, using React, React Native, Node.js, and AWS.
At Centro Hub, I developed critical UI components for a Core Banking Platform and integrated microservices APIs into modern React interfaces. I also helped deploy the application to the iOS App Store and Google Play, reaching more than 100,000 users.
At Technisys, I engineered core banking modules, integrated third-party SDKs for secure transactions, and delivered responsive web interfaces across desktop and mobile. I worked closely with Product and QA teams to validate and deploy high-quality frontend features.
Earlier at Kruger Corp and Zaycev Design, I built React applications, contributed to API architecture, used Spring Boot and JavaScript, and applied SonarLint and SonarQube to reduce technical debt. I take end-to-end ownership of turning business requirements into maintainable, mission-critical software.
