Ritik Raj

I'm a final-year Electronics & Communication Engineering student at BIT Mesra, currently working as a Software Engineering Intern at Oracle, where I build Java/JPA backend workflows for audit-log export systems. This includes handling SFTP delivery, asynchronous job processing, and failure-tracking across multiple receivers. Previously, at 21 Spheres, I built a MERN-based alumni engagement platform serving 6,000+ users, including authentication, role-based access, and automated email campaigns using AWS SES. Outside of internships, I build full-stack systems end to end: 🔹 CodeSyncX, a real-time collaborative code editor with Socket.IO, GitHub OAuth, and a secure Docker sandbox for executing untrusted code (resource-limited, network-isolated), deployed on AWS EC2 with Redis/BullMQ for async job execution. 🔹 ExamHelp RAG, an AI-powered PDF study assistant using FastAPI, FAISS, and LangChain, with a RAG pipeline for grounded Q&A, MCQ generation, and written-answer evaluation. I enjoy backend architecture, distributed systems, and turning ambiguous problems into reliable, production-ready services. Knight badge on LeetCode (top 5% globally, 1850+ rating), with 600+ DSA problems solved across platforms. Open to full-time SWE roles starting 2026. Happy to connect!
