RAG AI Data Fetch Structure

@mahads31

From the look of things, Mahad Sheikh is the one you need! I have a solid background in API development with proficiencies in Python and Node.js, both of which you're open to. By leveraging these technologies, I can build a lightweight service that securely connects to your existing MongoDB collection. Together, we'll create an efficient embedding/indexing routine adaptable for FAISS, Pinecone or a native MongoDB Atlas Vector Search. One critical point about me is my knack for transforming complex requirements into clean, scalable systems built for lasting success. It's clear that you want something efficient, reliable and tailored to promote growth—I'm already excited to work on this with you! Having worked with multiple international clients across several industries, your project falls right within my expertise range and I'm ready to implement RAG logic that will combine product fields with a language model prompt for rich, real-time answers. In addition, I guarantee timely execution: At most 500ms for the retrieval of any product information using either a text query or an ID. All queries will be enclosed within your internal MongoDB instance, leaving no room for external data sources.

Hi, I can build this end-to-end: FastAPI service connecting to your MongoDB cluster, an embedding/indexing pipeline (Pinecone or FAISS depending on your preference — happy to recommend based on your query volume), and a RAG layer that combines retrieved product fields with an LLM prompt for real-time answers. I've built several production RAG systems recently — including a multi-format RAG pipeline with FAISS/ChromaDB/Pinecone across three embedding models, and a voice AI agent with a live ChromaDB retrieval layer feeding an LLM in real time. I'm comfortable with the full stack you need: FastAPI, vector search, prompt engineering, and clean handover docs (README, sample .env, one-command startup). My plan: connect to your Mongo cluster and validate the schema first, then build the embedding/indexing and retrieval layer, wire up the RAG pipeline to hit your ID/free-text query requirement, tune for the sub-500ms latency target, and finish with a full handover (README, .env template, walkthrough). I'll share progress at each stage so you can course-correct early. I'm okay with the proposed budget of ₹6,300 for this scope. Ready to start as soon as I get access to a read replica or sandbox of your Mongo cluster.

Hello, I have 10 years of experience building AI-powered applications and integrating LLMs and OpenAI APIs into production workflows. For this project, I recommend a lightweight Node.js service with REST APIs, connected securely to your existing MongoDB cluster and restricted to internal product data. I can implement document preparation, embedding generation, vector retrieval, product-ID lookup, and RAG responses for search, chat, and merchandising use cases. The design will prioritize accurate product fields, low-latency queries, secure environment configuration, clean error handling, and a simple deployment process. I can use MongoDB Atlas Vector Search where suitable, or select another vector approach based on your current infrastructure and data volume. A first working prototype can be targeted within five to seven days. Let’s discuss your schema and preferred model provider. Best regards

Hi, I can build the RAG service using Python/FastAPI, MongoDB Atlas Vector Search, and an LLM integration for fast product search and responses. I’ll provide a clean configurable setup, sample environment file, documentation, and deployment-ready code. Thanks Anshuman

@AhmadXpert2410

Hi there, I understand you need a lightweight RAG layer that treats your existing MongoDB cluster as the single source of truth for product information. The important part is making retrieval fast and accurate enough for search, chat, and merchandising while ensuring the system never introduces external product data or stale information into the responses. I would recommend Python with FastAPI and MongoDB Atlas Vector Search where available, as it keeps the product data and vector retrieval close to the existing datastore and simplifies operational overhead. I can build the indexing pipeline, metadata-aware retrieval, product-ID lookup, and RAG layer with clean interfaces, environment-based configuration, and validation to ensure name, price, and description are retrieved from your internal MongoDB data within the required latency target. You'll receive a documented service with a sample `.env`, one-command startup, indexing/re-indexing workflow, retrieval APIs, and clear staging/production setup instructions. I can provide a first working prototype quickly after reviewing your MongoDB schema, expected query volume, and existing infrastructure, then optimize retrieval and caching as needed to meet the 500 ms requirement. Regards, Ahmad

Hi there, Your RAG layer is a good fit for my backend and data-integration experience, especially the requirement to keep retrieval strictly inside your existing MongoDB data while returning product information quickly. I’d focus on getting the retrieval path efficient first, then layer the LLM response generation on top. I have 8+ years of experience with Node.js, Express, NestJS, MongoDB, MySQL, PostgreSQL, REST APIs, payment gateways, and AWS. For this project, I can build the service with Python or Node.js, connect securely to MongoDB Atlas, and use native Atlas Vector Search where available to avoid maintaining unnecessary infrastructure. I can implement product-document chunking/embedding, vector indexing, metadata filtering, product-ID lookup, semantic search, retrieval ranking, and the RAG prompt pipeline. I’ll also ensure the LLM receives only retrieved internal product data, with no external knowledge source added to the retrieval flow. I’ve worked with API-driven applications, search/data pipelines, MongoDB-based systems, and AI/LLM integrations. I can provide a clean README, sample environment configuration, staging/production setup, logging, and a one-command startup process. I’d target a first working prototype within 3–5 days, then benchmark and tune the retrieval path against your 500 ms requirement. Happy to discuss your MongoDB schema and preferred embedding/model provider. Best, Jafarali

@alluankit01

Hi, I can build the lightweight RAG retrieval service for your e-commerce MongoDB product data. My approach will be to first review your MongoDB schema, product fields, query types, expected traffic, deployment setup, and preferred LLM/embedding option. Then I’ll create a secure Python FastAPI service that connects to MongoDB, indexes product records, supports product ID and free-text search, and returns product-aware answers using only your internal product data. I’m comfortable with Python, FastAPI, MongoDB, Atlas Vector Search, FAISS/Pinecone, embeddings, RAG pipelines, API development, NLP, environment configuration, and staging/production handover. Deliverables: * MongoDB connection layer * Product retrieval API * Product ID lookup * Free-text vector search * Embedding/indexing routine * RAG prompt pipeline * Secure .env configuration * Sample API requests * README setup guide * One-command start script * Basic logging and monitoring notes Preferred stack: Python + FastAPI + MongoDB Atlas Vector Search or FAISS, depending on your current MongoDB setup. Timeline: first working prototype in 3–5 days. I’ll focus on a clean, extendable service with fast retrieval, accurate product fields, and no external data sources beyond your internal MongoDB records. Best regards Ankit

@rohank2502

Your catalog already lives in MongoDB. You need a small Python service that, from your cluster only, returns name, price, and description in under 500 ms, then a prompt layer for richer answers. I build in Python daily. I have not delivered this exact RAG product, so I will not claim a RAG portfolio. I will stand up a live prototype on a slice of your real products so you judge latency and answers. Secure Mongo connection, Atlas Vector Search or FAISS, a retrieve-then-prompt layer, plus .env and README for staging and production. The language model is your key or local, your call. Once you share a read-only Mongo URI and a few product docs, a working prototype is in your hands in 48 hours, handover-ready by day 3. Send the connection string and two example questions you want answered first?

@CauaAlves

Given your sub-500ms target, I'd lean on MongoDB Atlas Vector Search rather than standing up a separate FAISS/Pinecone service - it keeps embeddings next to the source documents, skips a second network hop, and simplifies your staging/production setup to one connection string instead of two systems to monitor. I'll build the retrieval interface, an incremental embedding/indexing routine so new products get indexed without a full re-run, and the RAG prompt layer on top, all scoped strictly to your internal MongoDB instance per your acceptance criteria. Delivered with a clean readme, sample .env and a single start command. Do you have a preferred LLM provider already (OpenAI, Anthropic, etc.), or should I recommend one based on your latency target?

@shayankhan333

Hello, I will build a Python RAG service that securely connects to your MongoDB cluster, vectorises product documents, and returns name, price, and description under 500ms via a clean retrieval interface. I can start today. For the index, I will use MongoDB Atlas Vector Search to keep queries on your internal instance, with a readme and sample .env for easy hand-over. Questions: 1) Atlas Vector Search, FAISS, or Pinecone? 2) Which LLM should power the generation step, OpenAI or open-source? Looking forward to discussing further. Regards, Shayan.
