What you will learn
+Master LCEL (LangChain Expression Language) to compose robust chains
+Build production agents with persistent memory and custom tools
+Orchestrate complex workflows with LangGraph (state, routing, cycles)
+Deploy with FastAPI, streaming, caching, and monitoring
+Manage LLM costs, optimize latency, and implement resilience
+Observe and debug with LangSmith in production
Course program
Module 1: LCEL: LangChain Expression Language
3h00- LCEL vs raw API calls: when to use abstraction?
- Composition with the pipe operator: prompt | llm | parser
- Patterns: sequential, parallel, conditional chains
- Retry, fallback, timeout for production
- Workshop: resume analysis pipeline (summary + skills + level)
Module 2: Production agents: memory and tools
3h30- Conversational memory with Redis (multi-user persistence)
- Create custom business tools (Tool, StructuredTool, Pydantic)
- Error handling, retry logic, circuit breakers for external APIs
- Observability with LangSmith: traces, debugging, evaluation
- Workshop: customer support agent with knowledge base
Module 3: LangGraph: complex workflows with state
4h00- LangGraph vs ReAct agents: explicit control vs LLM-driven
- State management: TypedDict, Annotated, operator.add
- Conditional routing: conditional_edges, quality-based retry
- Human-in-the-loop with checkpoints (MemorySaver, RedisSaver)
- Workshop: company data enrichment pipeline
Module 4: Deployment and production patterns
3h30- FastAPI with streaming (Server-Sent Events)
- Cost management: Redis caching, semantic cache, prompt optimization
- Monitoring: Prometheus, Grafana, metrics (latency, cost, errors)
- Circuit breaker for external dependencies
- Production checklist: health checks, rate limiting, secrets, logs
