I developed RESTful APIs using Spring Boot for the backend, ensuring efficient communication and smooth data handling. On the frontend, I worked extensively with React.js, creating interactive and user-friendly applications that provided seamless user experiences.I containerized and orchestrated application deployments using Docker and Kubernetes (K8s), allowing for scalable, consistent, and reliable environments that could easily handle increased demand and complex architectures.To streamline software delivery, I managed CI/CD pipelines with Jenkins, enabling automated builds, tests, and deployments. This significantly reduced manual effort, minimized errors, and ensured faster release cycles.I designed and integrated APIs with Spring Security, implementing robust security protocols to ensure secure data exchanges and protect applications from potential threats.As part of my work, I integrated payment gateways, ensuring secure and efficient transaction processing. This involved handling sensitive data with care, following best practices for encryption and authentication.I wrote and executed JUnit test cases to validate the functionality of my code, helping maintain high-quality standards and ensuring the reliability of the applications I developed. Through rigorous testing, I was able to catch potential issues early and deliver stable, bug-free software.

I performed functional testing using Selenium, TestNG, and Cucumber, where I developed and executed automated test scripts. This ensured comprehensive test coverage, validating critical functionalities and maintaining high-quality software standards throughout the development lifecycle.I conducted performance testing with JMeter, allowing me to evaluate the scalability, load handling, and overall performance metrics of applications. By simulating real-world usage, I identified bottlenecks and optimized performance to ensure applications could handle high traffic.I designed and implemented detailed test plans and test cases for both functional and performance testing. These plans helped to organize testing efforts, ensuring that all features and performance aspects were thoroughly validated.I worked closely with development teams to validate API functionality and performance, ensuring secure, reliable, and efficient data interactions. This collaboration allowed for early identification of issues, leading to smoother API integrations and robust software solutions.I developed and managed RESTful APIs using Spring Boot, creating scalable and reliable backend services that powered various applications. My focus was on building APIs that were not only efficient but also secure, ensuring smooth communication between systems.
