About Hemanth K

I’m a Java Full Stack Developer with over 4.5+ years of experience designing, developing, and deploying secure, high-performance enterprise applications using Java 8/17, Spring Boot, React.js, Angular, and AWS. My expertise spans microservices architecture, REST API development, cloud-native deployment, and DevOps automation.I specialize in building scalable backend systems with Spring Boot, Spring Cloud, and Hibernate/JPA, integrating event-driven workflows through Apache Kafka and caching mechanisms such as Redis. On the front end, I develop responsive React and Angular applications leveraging TypeScript, and Redux for seamless, data-driven user experiences. I’m passionate about delivering clean, testable code and maintaining end-to-end CI/CD pipelines using Jenkins, Docker, and GitHub Actions. I have hands-on experience with AWS services (EC2, S3, Lambda, API Gateway, RDS) and container orchestration for reliable, scalable deployments.Known for my collaborative approach and problem-solving mindset, I thrive in Agile/Scrum environments, ensuring that every release meets quality, security, and performance goals while driving continuous improvement and innovation.
