Built an enterprise-grade Retrieval-Augmented Generation (RAG) pipeline designed for
high-performance semantic search and autonomous document ingestion.
Engineered a sophisticated multi-tier caching architecture
(L1/L2/L3) to drastically reduce latency and improve query response times
Built automated pipelines for web scraping, PDF parsing, and
chunking, seamlessly integrated with a custom Composite File System (CFS)
Implemented Rotary Position Embeddings (RoPE) and integrated
Qdrant Vector Database for highly scalable and accurate semantic search
Designed robust data integrity mechanisms utilizing
Write-Ahead Logging (WAL) and adaptive task scheduling

Designed and simulated an AI-powered Hospital IVR system replacing legacy DTMF navigation with a
hybrid ILP-AI architecture for automated symptom triage and emergency ambulance dispatch.
Architected a hybrid ILP + SLM pipeline using Gemini-2.5-flash
for
clinical reasoning and SCIP for optimal ambulance-to-patient assignment
Integrated Chirp embedding model for speech-to-text conversion
and
intent detection
Designed an NLU pipeline with speech-to-text, intent
detection, distress classification, and clinical NER for multi-language scenarios
Simulated a microservices backend (NestJS + Python) with
PostgreSQL and Redis, handling 1,000+ concurrent call scenarios at 99.9% uptime

Worked on building a scalable AI-powered document query system for enterprise users, enhancing
document search and retrieval using NLP and vector search technologies.
Developed a full-stack RAG system using FastAPI, Streamlit,
MongoDB, Qdrant, and Hugging Face Transformers
Implemented real-time semantic search across multiple PDFs
with support for voice-based queries
Improved document search speed by 80% with enterprise-grade
concurrent request handling

Contributed to the end-to-end development of a Restaurant Management System tailored for a local
business client, focusing on order processing, menu management, and billing features.
Developed the backend using Java and MySQL, and built user
interfaces with Java Swing
Designed modules for order tracking, table reservation, and
inventory management
Delivered the solution with 100% on-time delivery and zero
