At Coppel, I build enterprise applications from the ground up with Java 17/21, Spring Boot, Angular, and microservices. I developed backend workflows that process up to 5M records from files and database sources using chunk-based processing and concurrent operations.
I built a multi-channel campaign platform with scheduling, monitoring, and user interfaces, and a banking phone-management platform integrating nine services for validation, registration, confirmation, and automated data cleanup. I also implemented end-to-end authentication and authorization with security filters, roles, and tokens.
I optimize database performance, reducing stored-procedure execution time by approximately 33%, and build full-stack features with TypeScript, RxJS, NgRx, and API integrations. Earlier, I developed a responsive e-commerce application with Java, Spring Boot REST APIs, SQL, JavaScript, HTML, CSS, and Bootstrap.
