Featured AI Projects
RAG Document Q&A with Groq API and Llama3
A retrieval-augmented generation chatbot that answers questions about documents, using Llama3 served through the Groq API, ChromaDB as the vector store, and LangChain for the pipeline.
Search Engine GenAI App Using Tools and Agents
A semantic search engine where an LLM agent decides which tools to call to answer a query, built with LangChain agents and tools.
Constructing Insight: Real-Time Object Detection in Construction Sites
Real-time detection and classification of buildings, equipment, and workers on construction sites to improve safety and efficiency, using YOLO and TensorFlow on the Pictor-v2 dataset.
Automated Brain Tumor Detection and Classification (2024)
Detects and classifies brain tumors from MRI scans with CNNs and transfer learning in TensorFlow, to support diagnosis where skilled neurosurgeons are scarce.
Generative AI & LLM Applications
13 projects
Conversational Q&A Chatbot with PDF Support
Upload PDF documents and hold a conversation about their contents, using LangChain retrievers and memory, ChromaDB, and Streamlit.
Chat with SQL Database Using LangChain SQL Toolkit
Ask questions about a SQL database in plain English instead of writing queries, built with the LangChain SQL toolkit and agents and Streamlit.
Multi-Language Code Assistant Using CodeLlama
A coding assistant that generates syntactically correct code in multiple programming languages, using CodeLlama and LangChain.
Generative AI with AWS Bedrock and Lambda
Designed and deployed generative AI applications on AWS, including a document Q&A app on Bedrock and a blog generation app on Lambda.
Simple GenAI App Using Ollama
A lightweight chatbot that runs a large language model locally with Ollama and LangChain, so it works offline without an external API.
Text Summarization Using LangChain
Concise, coherent summaries of text using LangChain's Stuff, MapReduce, and Refine summarization chains.
End-to-End Q&A Chatbot with OpenAI
A context-aware question-and-answer chatbot with real-time conversational answers through a web interface, built with the OpenAI API, LangChain, and Streamlit.
Q&A Chatbot Using Ollama (Open Source)
The OpenAI-based Q&A chatbot rebuilt on Ollama and open-source models instead of a paid API.
YouTube and Website Content Summarization
Takes a YouTube video or website URL and returns a summary of its content, using the YouTube Transcript API and LangChain loaders and splitters.
PDF Query RAG with AstraDB
A scalable document query system that answers questions about PDFs with retrieval-augmented generation on AstraDB.
Hybrid Search RAG with Pinecone
Hybrid retrieval combining semantic and keyword search in Pinecone, merged with Reciprocal Rank Fusion.
Hugging Face Integration Project
Open-source Hugging Face transformer models integrated into LangChain for custom text generation and summarization pipelines.
Fine-Tuning LLMs Using Lamini and Google Gemma
End-to-end LLM fine-tuning, from custom dataset preparation to training and optimization, using Lamini AI Cloud, Google Gemma, LoRA, and QLoRA.
