Sri Lakshmi R
Java Backend Developer
Hi, I'm Sri Lakshmi 👋
I'm a Java Backend Developer with 4+ years of hands-on experience building, maintaining, and deploying backend systems using Java, Spring Boot, REST APIs, and databases.
I have worked in startup and contract-based environments, handling real production systems, data migration, cloud deployment, and long-term application maintenance.
About Me
I started my career with a strong interest in backend development and gradually built experience by working on real-world applications.
Over the years, I have contributed to backend systems that required reliability, scalability, and clean API design. I am comfortable working independently as well as collaborating with frontend, QA, and product teams.
I enjoy solving backend problems, improving system stability, and supporting applications in production environments.
