AGENTIC AI & STATEFUL MULTI-AGENT· Sep 2024 — Present· Principal AI Systems Architect

Eva Tek · Enterprise Sovereign Agent Engine

Stateful multi-agent runtime on GCP with LangGraph, Redis checkpointing, MCP tool interfaces, and local SLM fallbacks.

Context & Engineering Constraints

Enterprise teams need autonomous agents that execute multi-step business logic without losing state or violating strict compliance boundaries. This runtime was architected to keep execution deterministic, state inspectable, and inference resilient against upstream outages.

Architecture & System Approach

  • 01Modeled end-to-end B2B and research workflows as typed, finite state graphs using LangGraph with human-in-the-loop gates.
  • 02Engineered durable state recovery with Redis checkpointing, ensuring long-running agents recover seamlessly from process failures without re-spending tokens.
  • 03Implemented Model Context Protocol (MCP) tool calling governed by strict Pydantic JSON schemas to eliminate hallucinations.
  • 04Built automated circuit breakers that dynamically route to self-hosted open-weight SLMs when upstream LLM APIs experience degradation.

Measurable Business & Technical Outcomes

  • Reduced inference latency and token consumption by over 40% via dynamic prompt compression and step-level caching.
  • Maintained 99%+ system uptime through high-availability Kubernetes runtime with automated fallbacks.
  • Delivered full auditability with OpenTelemetry step-level distributed tracing and TruLens evaluation guardrails.

“Production reliability is not an afterthought—it is a property of the entire system boundary: typed schemas, explicit state machines, durable recovery, and deterministic human oversight.”
