I am a detail-oriented Java Full Stack Developer with 4+ years of experience in designing, developing, and maintaining scalable web applications. I specialize in building robust backend services with Java, Spring Boot, Hibernate, and MongoDB, while delivering polished front-end interfaces using React, Redux, and modern web technologies. I thrive in collaborative, Agile environments and am passionate about turning complex requirements into reliable, user-friendly software. In recent roles at Mastercard and CSX, I led API design, implemented secure microservices on AWS, improved system reliability by optimizing resource management, and reduced deployment friction with automated CI/CD pipelines. I also leveraged AI-assisted development tools to accelerate debugging and code quality, while mentoring teammates to adopt best practices in software design and testing.
