Hi, I'm Shikhar Saxena

Full Stack / Backend Engineer — Node.js & Java Ecosystems

Backend-focused engineer building scalable, distributed systems across both the Node.js/AWS and Java/Spring ecosystems — REST & GraphQL APIs, event-driven architectures, cloud infrastructure, and increasingly, LLM-powered agentic workflows.


🧑‍💻 About Me

  • 🏗️ I build backend systems end-to-end — API design, data modeling, caching, deployment, and observability
  • 🔀 Comfortable working across two backend ecosystems: Node.js/TypeScript on AWS, and Java/Spring Boot on Kubernetes
  • 📨 Experienced with event-driven architecture — background workers, message queues, webhook pipelines, and Kafka-based streaming
  • 🔐 Strong focus on secure, well-tested services — JWT, OAuth2, RBAC, and high automated test coverage
  • 🤖 Recently building LLM-powered agentic workflows — RAG pipelines, embeddings, vector search, and tool-calling (including LangChain-based agents)
  • ☁️ Deep AWS experience, plus Docker/Kubernetes-based deployment pipelines
  • 📫 Reach me at shikhar.dev2001@gmail.com
