ABOUT NIKUNJ RANA
I’m a Full Stack Software Engineer with 6+ years of experience building backend-heavy systems using Java, Spring Boot, REST/GraphQL APIs, and React. I specialize in designing clean APIs, optimizing performance, and maintaining production stability in real-world environments.Recently, I’ve worked on reducing API latency through SQL optimization and Redis caching, improving observability with Datadog APM, and strengthening backend reliability in production systems. I also built a Dockerized Retrieval-Augmented Generation (RAG) pipeline using GPT-4 and ChromaDB during my Master’s at San José State University, combining modern AI systems with practical backend engineering.I enjoy solving performance bottlenecks, improving system stability, and building scalable, maintainable services. My background in Data Science further helps me work effectively with data-heavy systems and analytics-driven platforms.
