Dedicated Developer
A LangChain developer works exclusively on your project, integrated with the tools and workflows your team already uses.
Best for Ongoing LangChain pipeline work and eval iteration

LangChain Development, Accelerated with AI
Systematic Prompt Engineering
AI assisted prompt optimization with A/B testing, evaluation datasets and regression tracking, so your prompts improve over time instead of degrading with model updates.
Automated Evaluation Pipelines
Evaluation runs in LangSmith check your chains and agents against datasets from your own domain, so accuracy drops and hallucinations show up in review instead of in front of users.
Production Observability
End to end tracing of every LLM call, retrieval step and agent action, with token usage tracking, latency monitoring and error alerting for production systems.
Cost Efficient Architecture
AI analyzes usage patterns to recommend caching, model routing (a stronger model for hard tasks, a cheaper one for simple ones) and batching that reduce LLM costs.
What Our LangChain Developers Build
AI Agent Development
Multi-step agents using LangGraph that reason, use tools, and complete complex tasks autonomously. Customer support, research, and workflow automation agents.
RAG Systems
Retrieval-augmented generation with vector databases. Domain-specific Q&A, document analysis, and knowledge management systems grounded in your data.
LLM-Powered Workflows
Automated content generation, document processing, classification, and extraction pipelines using chained LLM calls with structured outputs.
Multi-Model Orchestration
Systems that route between OpenAI, Anthropic Claude, and open source models based on task complexity, cost, and latency requirements.
Conversational AI
Context-aware chatbots and conversational interfaces with memory, tool access, and domain knowledge for customer-facing and internal applications.
LangChain Migration & Optimization
Migrate existing LLM applications to LangChain, optimize underperforming chains, and add evaluation and monitoring to production systems.
VETTING PIPELINE
How engineers earn a spot on our team
Our hiring process has three stages, from the application screen to a project deep dive with background verification, and every new engineer then serves a probation period.
4 checks
Application screen
We source engineers across India through LinkedIn, Wellfound, employee referrals and outbound headhunting. Every application is checked for stack relevance, years of experience, English and time zone overlap before it moves to a technical interview.
60 to 90 min
Live coding and scenario questions
A live coding round of 60 to 90 minutes in the primary technology of the candidate, followed by scenario based questions on practical applications of that technology.
3 checks
Project deep dive and background verification
Candidates walk us through a recent production project, covering the architecture decisions and what they would change in hindsight. A third party background verification agency then confirms prior employment, education and identity.
Probation
A probation period follows
New engineers then serve a probation period, and those who do not meet our bar do not continue with us.
How It Works
From the first call to a developer working in your team, you choose who joins and when.
Share your requirements
Tell us the experience level, tech stack, project scope and team setup you need. A 30 minute call is usually enough.
Review shortlisted profiles
Vetted candidates are presented within a week, matched to the brief you shared.
Interview your picks
Interview shortlisted developers directly, through technical interviews, pair programming or whatever your process requires.
Onboard and start
Your developer joins your tools and standups, and onboarding completes in 7 to 14 business days.
Engagement Models
Managed Team
We assemble and manage a LangChain team with a tech lead, handling delivery end to end against your requirements.
Best for Building agent and RAG systems end to end with a lead
