I'm Raj Tripathi, a Computer Science Engineer with a focus on systems-level programming, AI infrastructure, and full-stack development. My work spans across multiple layers of the stack — from low-level C data structures to distributed multi-agent LLM pipelines.
My technical interests lie at the intersection of:
- AI & LLM Engineering — Building multi-agent systems using LangChain, LangGraph, and RAG pipelines; fine-tuning models with LoRA and knowledge distillation; designing evaluation and observability frameworks for agentic workflows
- Systems Programming — Implementing core data structures (vectors, hash tables, stacks) from scratch in C, with a focus on memory safety, pointer semantics, and low-level performance optimization
- Full-Stack Engineering — Architecting secure, scalable applications on the MERN stack with JWT auth (refresh rotation, HttpOnly cookies), RBAC, NoSQL injection prevention, and sub-150ms API response targets
- MLOps & Infrastructure — End-to-end ML lifecycle management, TensorFlow/PyTorch model deployment, Docker, Kubernetes, CI/CD pipelines, and AWS
