As a Software Developer Engineer, I have developed and maintained Single Page Applications (SPA) using Angular and Java, designing responsive UIs with Angular 12, HTML5, CSS3, and TypeScript. I built RESTful APIs and microservices with Spring Boot, optimized database schemas in MySQL and MongoDB, and developed server-side logic for handling client requests. I contributed to transitioning monolithic applications to a microservices architecture, ensuring scalability and fault tolerance. I also designed secure APIs, integrated third-party services, and participated in Agile practices, including daily stand-ups and code reviews. Testing included unit and API validation using JUnit, Mockito, and Postman. I leveraged Git for version control and Jenkins for deployment in CI/CD pipelines. Key achievements include reducing API response times by 25% and improving user engagement by 15% through new feature development.
