PROJECTS

AI Helper 2025 - Present (In progress)

Hybrid RAG System: Built a Retrieval-Augmented Generation pipeline combining pgvector similarity search
and full-text search, optimized with Reciprocal Rank Fusion (RRF).
AI Study Automation: Implemented automated PDF summaries, chat, key points, and exam question
generation using Gemini 2.5 Flash.
Async Backend Architecture: Developed a fully asynchronous FastAPI + SQLAlchemy 2.0 stack with streaming
(SSE) and intelligent caching.
Production & Security: Added JWT-based dual-token auth (Access/Refresh), real-time streaming, cost-
optimized caching, and LangSmith observability.
