About

Hi, I'm Neeraj Mishra — a Java Backend Developer and 2026 B.Tech CSE graduate from Lovely Professional University, specializing in building scalable, production-ready backend systems. 🔧 Tech I work with: Java | Spring Boot | Spring Security | Spring AI | REST APIs | MongoDB | JWT | OAuth2 | AWS S3 | MinIO | Docker (basics) 🤖 What makes me different: I have hands-on experience integrating LLMs and RAG pipelines into real Spring Boot applications using Spring AI — a skill that very few 2026 batch freshers have. I built Nexus AI, a B2B sales automation backend that uses vector search and LLM-based response generation. 💼 Experience: Completed a Backend Development Trainee internship at Contriverz (Mohali), where I built secure REST APIs, JWT authentication, and a MinIO/AWS S3-based file storage system in a production Agile environment. 🧠 Problem Solving: 400+ DSA problems solved on LeetCode (Handle: _Mishra_) with consistent streaks across LeetCode and GeeksforGeeks. ☁️ Certified: Microsoft Azure Fundamentals (AZ-900) Currently seeking SDE, Backend SDE, or Backend Intern roles (India / Remote) — 2026 batch, immediate joiner. 📩 Let's connect: mishra.neeraj.1011@gmail.com
