About Nagaraj G

I’m a Site Reliability / DevOps Engineer focused on building reliable cloud platforms, scalable backend systems, and modern data infrastructure.My journey began with a Master’s degree in Computer Network Technology from Northumbria University (UK), followed by hands-on experience in DevOps and cloud engineering across organizations like Accenture, Capgemini, Mindtree, Athenahealth, and currently at Walmart. Over the years, I’ve worked on CI/CD automation, cloud infrastructure, and microservice platforms while collaborating with globally distributed teams.Today, I work across cloud infrastructure and backend systems, using technologies such as AWS, Azure, Kubernetes, Serverless, Terraform, Python, Node.js, FastAPI, GraphQL, various SQL & NonSQL Databases, MongoDB and CI/CD pipelines to design and operate scalable platforms.Recently, I’ve been building AI-powered systems using Retrieval-Augmented Generation (RAG). One of my current projects involves designing a RAG architecture where various system involves PostgreSQL, data ingestion into a vector database (Milvus), intelligent query routing, and LLMs contextual responses.I enjoy working at the intersection of cloud infrastructure, data platforms, scalable data pipelines, and AI systems, building solutions that are scalable, reliable, and intelligent.
