LangChain Development, Accelerated with AI
Systematic Prompt Engineering
AI-assisted prompt optimization with A/B testing, evaluation datasets, and regression tracking ensures your prompts improve over time rather than degrading with model updates.
Automated Evaluation Pipelines
LangSmith-powered evaluation frameworks test your chains and agents against domain-specific benchmarks, catching accuracy drops and hallucinations before users do.
Production Observability
End-to-end tracing of every LLM call, retrieval step, and agent action. Token usage tracking, latency monitoring, and error alerting for reliable production systems.
Cost-Efficient Architecture
AI analyzes usage patterns to recommend caching strategies, model routing (expensive vs. cheap models by task), and batching approaches that reduce LLM costs by 40-60%.
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 GPT-4, 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
Every engineer goes through the same four-stage funnel. Most do not make it past stage two.
30,000+
Applications received each year
Around 15 open roles at any time, each receiving roughly 200 applications per month through LinkedIn, AngelList, employee referrals, and outbound headhunting across India. India produces 1.5 million CS graduates a year, so sourcing is not the moat. Filtering is. Most applications are auto-filtered for stack relevance, years of experience, English, and time-zone overlap before any human reviews them.
5%
Pass live coding + system design
Two-stage technical interview: a 90-minute live coding exercise tailored to the candidate's primary stack, then a system-design discussion grounded in real production scenarios.
2%
Pass project deep-dive + background verification
We ask candidates to walk through a recent production project: architecture decisions, what they would change in hindsight. We also run a background verification check through a third-party BGV agency to confirm prior employment, education, and identity.
1.2%
Complete 2-week shadow onboarding
A senior Unico Connect engineer shadows new hires for two weeks on an internal project. We watch how they respond to feedback, ask for help, and ship code. Fast learners stay.
<1%
of applicants join the active team
A dedicated team of engineers makes up the active Unico Connect team at any given time across all stacks. New roles open as engagements complete or grow.
How It Works
From first conversation to a developer shipping code on your project, the process is designed to be fast, transparent, and low-risk.
