Allia

Founding AI Engineer · 2025–Now

Allia brings AI into accounting workflows where documents arrive at volume, domain context matters, and every answer needs to remain useful under real operating constraints.

What I worked on

  • Designed the multi-agent runtime with LangChain and LangGraph, hybrid retrieval, domain tools, and MCP integrations.
  • Built evaluation and tracing with Langfuse to measure grounding, citations, latency, cost, and failure modes.
  • Made high-volume document ingestion durable with Temporal workers, bounded concurrency, and batched vector writes.

In production

  • Approximately 340,000 workflows each week.
  • Approximately 89% fewer critical failures in internal evaluation.

System: Agent harnesses · Context engineering · MCP integrations · Temporal · Langfuse

The recurring lesson is simple: the harness and feedback loop matter as much as the model. Context, tools, evaluation, and runtime behavior must work as one system.
