# Ritik Raj on Tal

## Headline

Former SDE Intern @ Oracle \| Java & Node\.js Backend Developer \| Built RAG & Real\-Time Systems \| LeetCode Knight \(Top 5%\) \| BIT Mesra

## About

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\!
