Product
RAG Chatbot Systems
Production RAG chatbots with document ingestion, chunking, embedding, retrieval, and GPT-4 generation — grounded in your specific data.
LangChain Development — Production RAG Pipelines and AI Agent Systems
We build production LangChain applications — RAG chatbots, multi-step AI agents, document processing pipelines, and LLM orchestration systems that go from proof-of-concept to production.

What We Build
What We Build With LangChain Development
Production applications across product types — scoped to your users, stack, and growth stage.
6 product types — compare what we ship with LangChain in production.
- Platform
Multi-Step AI Agents
LangGraph-based agents that use tools, call APIs, query databases, and execute multi-step tasks autonomously with state management.
- SaaS
Document Processing Pipelines
LangChain document loaders, text splitters, and chains for automated extraction, classification, and summarisation of large document sets.
- Commerce
Conversational AI with Memory
Chat applications with conversation memory — window buffer, summary buffer, and vector store memory for contextually aware multi-turn conversations.
- Internal
LLM Evaluation Systems
RAGAS and custom evaluation pipelines for testing RAG accuracy, faithfulness, and context relevance in production.
- Design
LangServe API Deployment
Productionising LangChain chains as REST APIs using LangServe — standardised endpoints, streaming support, and LangSmith tracing.
WHY CODEFLAMME
Not Another Offshore Vendor
We know the hesitation. Here's exactly how we're different.
You Talk to the People Building It
No account managers relaying messages. You're in direct contact with the founder and senior engineers on your project — every sprint, every decision.
No Bench Rotation
The team that scopes your project is the team that ships it. We don't swap engineers mid-project to free them up for someone else.
NDA Before We Talk Details
Your idea and IP are protected from the first real conversation — not after contracts are signed.
Full IP, Zero Strings
Every line of code, every design file, transfers to you on delivery. No licensing, no retained rights, no surprises.
Our Capabilities
Our LangChain Development Services
Core delivery areas for LangChain — architecture, implementation, and production hardening.
- 01
RAG Architecture Design
Chunking strategy selection (recursive, semantic, parent-document), embedding model choice, retriever configuration, and context window management.
- 02
Vector Store Integration
Pinecone, Weaviate, pgvector, and Chroma integration — index design, metadata filtering, and hybrid search (dense + sparse) setup.
- 03
LangGraph for Agents
Stateful agent graphs with LangGraph — nodes, edges, conditional routing, parallel execution, and human-in-the-loop checkpoints.
- 04
Prompt Template Management
LangChain prompt templates, few-shot examples, output parsers, and chain composition for maintainable LLM pipelines.
- 05
LangSmith Observability
LangSmith tracing setup, run inspection, evaluation datasets, and production monitoring for LangChain-based applications.
- 06
Memory Systems
ConversationBufferWindowMemory, ConversationSummaryMemory, and VectorStoreRetrieverMemory for appropriate conversation history management.
When to Choose
When LangChain Development Is the Right Choice
Decision scenarios where LangChain is the strongest fit — and why it earns the recommendation.
SCENARIO 01
Primary use case
You are building a RAG application
LangChain provides the most mature and flexible RAG tooling available — document loaders, text splitters, retrievers, and chains for every component of a RAG pipeline.
02
Scenario
You need AI agents with tools
LangGraph's stateful agent framework is the current best practice for building reliable multi-step AI agents — better than React alone.
03
Scenario
You want to switch LLM providers
LangChain's LLM abstraction layer makes switching between OpenAI, Anthropic, Cohere, and local models a single-line change.
04
Scenario
You need production observability for LLM workflows
LangSmith provides the only purpose-built observability solution for LangChain applications — trace inspection, latency analysis, and evaluation.
