Working independently as a backend developer, designing and building production-grade REST APIs and AI-integrated systems. Key work includes: - Built a Django REST API with custom Role-Based Access Control (RBAC) across 3 user roles, JWT authentication with sliding token expiry, and PostgreSQL — achieving 87% test coverage using pytest, which caught a real edge-case bug before deployment. - Architected a full-stack Retrieval-Augmented Generation (RAG) system (TruthLens AI) using FastAPI, ChromaDB, and GPT-4o-mini for automated misinformation detection — including semantic search, structured JSON outputs, and graceful fallback handling for LLM/embedding failures. - Containerized and deployed backend services using Docker to Render, with React + Vite + TailwindCSS frontends deployed to Vercel, achieving full-stack cloud deployment experience. - Focused on writing clean, well-tested, maintainable code and optimizing database queries (eliminating N+1 query issues using Django ORM's select_related and annotate()). Currently expanding expertise in AI-integrated backend systems, vector search, and production-grade API design while pursuing B.Sc in Computer Science at KIIT University.
