Our AI Technology Stack

Production-grade tools and frameworks for building, deploying, and monitoring agentic AI systems.

LangChain & LangGraph

The industry standard for building stateful LLM applications. We architect complex multi-agent workflows with conditional branching, parallel execution, and persistent state management across long-running conversations.

  • Multi-agent orchestration with role specialization
  • Conditional routing and dynamic tool selection
  • Checkpointing for resumable long-running tasks

RAG & Vector Databases

Retrieval-Augmented Generation with pgvector on PostgreSQL — zero lock-in vector storage that runs in your existing database. Semantic search, hybrid retrieval, and citation-aware responses for enterprise knowledge bases.

  • pgvector on PostgreSQL (no Pinecone/Weaviate lock-in)
  • Hybrid search (semantic + keyword + metadata filters)
  • Document chunking and embedding optimization

LangSmith Observability

Full tracing, evaluation, and monitoring for every agent interaction. Debug complex multi-step reasoning, track token budgets, and ensure quality with automated evaluations and human feedback loops.

  • End-to-end request tracing across agents
  • Automated evaluation datasets and regression testing
  • Cost tracking and performance analytics

Deployment & Infrastructure

LLM-agnostic deployment on your infrastructure — AWS, Azure, GCP, or on-premises. FastAPI/Node.js backends with LangServe, REST, or WebSocket protocols. OAuth2/JWT enterprise authentication and rate limiting.

  • OpenAI, Anthropic, Azure OpenAI, or self-hosted models
  • Docker/Kubernetes deployment with auto-scaling
  • VPC isolation and private endpoint configuration

Enterprise-Grade AI Safety

Agentic AI doesn't mean autonomous without oversight. We build human-in-the-loop safeguards into every system — approval workflows, escalation paths, and complete audit trails for regulated industries.

Human approval gates for critical actions
PII redaction and data privacy controls
Full audit logging for compliance (GDPR, HIPAA, SOC2)
