You will get a Custom Multimodal RAG Application Developed with OpenAI and LangChain
Top Rated
Project details
I will build a custom RAG (Retrieval Augmented Generation) application using OpenAI and LangChain that lets you query your private data with accurate, context-aware AI responses.
This solution is ideal for AI chatbots, internal knowledge bases, customer support assistants, or SaaS features, and is designed to be secure, scalable, and production-ready.
What you get:
➤ Custom RAG pipeline with OpenAI + LangChain
➤ Private data ingestion (PDFs, Docs, DBs, URLs)
➤ Vector database setup (Pinecone / Qdrant / Weaviate)
➤ Reliable, grounded AI responses
➤ Clean API-based backend
🎁 Free Bonus: I’ll review your use case and recommend the best RAG architecture before we start.
📩 Send your data source and goal to get started.

Simple Arabic NLP – QARiB Fine-Tuning Project (University Term Project)
Although the project title included the word “Simple”, the actual work was far from simple.
Bechir handled the project with a high level of professionalism and strong technical expertise.
Bechir delivered a high-quality academic NLP project with strong technical depth.
The methodology, experiments, and results were clearly explained and well structured, in a style very close to real academic research papers.
He was responsive, cooperative, and willing to revise the work to align with detailed requirements fully.
He is honest, dedicated, and reliable, and I would gladly work with him again.
