AI Agent & LangGraph Engineer
Orchestrating reliable, autonomous multi-agent systems.
Sharon Rosario designs and ships production AI agents and multi-agent systems with LangGraph — deterministic, self-correcting, observable pipelines rather than fragile single-prompt scripts.

AI Agent & LangGraph Engineer — overview
Most "AI agents" are a single large prompt hoping for the best, and they fail unpredictably in production. Sharon Rosario builds agents the way reliable software is built: as explicit state machines with defined steps, verification, and self-correction — using LangGraph to make the control flow deterministic and debuggable.
The engineering challenge with agents is not getting a good answer once; it is getting a correct answer reliably, knowing when the agent is wrong, and recovering without human intervention. Sharon designs multi-agent pipelines — researcher, writer, verifier roles — with observability so failures are diagnosable rather than mysterious.
Agents that are actually production-ready
Explicit state and control flow with LangGraph instead of one monolithic prompt. Verification and self-correction loops so the system catches its own mistakes. Observability with tools like LangSmith so you can see exactly where a run went wrong. And guardrails so an autonomous system fails safely.
This turns "impressive demo" into "dependable feature" — the difference that decides whether agents can ship to customers.
Multi-agent orchestration
Sharon builds pipelines where specialized agents hand off state to each other — for example a Researcher-Writer-Verifier loop — with the coordination logic made explicit and testable. The LangGraph case study below walks through the full architecture and hardening patterns.

A single "God prompt" is non-deterministic and hard to debug. LangGraph models an agent as an explicit state machine with defined steps, verification, and self-correction, so the workflow is reliable, testable, and observable — production-ready rather than demo-only.
Specialized agents — for example researcher, writer, and verifier — pass state between defined steps with explicit coordination logic and self-correction loops, rather than one prompt trying to do everything at once.
Explicit state management, verification and self-correction, observability with tools like LangSmith, and guardrails so the system fails safely. The LangGraph case study documents these patterns in detail.
