Agentic Systems Architect

Architecture of
agentic systems.

I engineer compound systems that separate probabilistic reasoning from deterministic execution. Fifteen years across ML, LLMs, and agentic AI — building architectures that survive in high-liability clinical and enterprise environments.

Architecture Diagram

The Bifurcated Engine

We do not pass raw neural output directly to execution vectors. Our systems are split into two completely isolated environments that communicate only through strict structural compilers.

Bifurcated Neuro-Symbolic AI Engine Architecture
[REASONING // 02]

The Stochastic Field

Intelligence requires constraints. We architect reasoning engines that creatively explore solution spaces, distilling neural output into strict deterministic execution graphs. The LLM is not the system — it is an untrusted guest operating within a pre-validated stochastic range, free to innovate but never free to execute.

Where open-weight SLMs and reasoning agents creatively explore non-linear solution spaces, run multi-agent debates, and generate candidate traces without production risk.

Perception Ingestion

Multimodal Signal Fusion

Converts raw text, medical telemetry, and time-series data (TimesFM) into initial embeddings.

Exploratory Planning

Parallel Sub-Agent Swarms

Isolated agents running LangGraph cycle-states, fanning out to model hypothetical paths.

The Deterministic Vault

Enterprise autonomy requires absolute reliability. Every neural output is intercepted by a rigid state machine that strips linguistic variance and enforces mathematical invariants. Governance, validation, and recovery come first. Intelligence is earned — never assumed.

The absolute state platform. This rigid containment unit intercepts candidate graphs, strips away linguistic variance, and executes code via immutable transactional state lines.

Symbolic Compilation

Constrained JSON Graph Compiler

Distills neural traces into strict mathematical DAGs, validating schema layout before runtime.

Policy-as-Code Veto

OPA / Rego Governance Firewall

Applies non-negotiable clinical and business invariants. Catches and neutralizes hallucinations natively.

Idempotent Commit

[ORCHESTRATION // 03] Platform Scale

Executes transactional tasks through gRPC agents with cryptographic logging and telemetry tracing.

Production patterns

We classify systems by what must never happen. Each pattern is a control structure binding neural generation to strict deterministic verification.

Pattern A

Guarded Execution

Liability: A wrong action causes irreversible harm.

A deterministic rules engine controls the workflow. Neural models handle bounded fuzzy-logic tasks, but the symbolic engine owns execution, veto, and fallback. There is no override.

Use cases: Clinical decision support, autonomous vehicles, grid balancing.

Pattern B

Verify-then-generate

Liability: A wrong conclusion wastes resources but is correctable.

A neural reasoner proposes a solution. An external ontology or graph verifies it. Violations trigger a self-correction feedback loop. Maximum iterations lead to a deterministic fallback.

Algorithmic Arbitration

Liability: Competing autonomous actors sharing resources.

Neural agents propose strategies. A compiled mathematical engine (Nash equilibrium solver, VCG auction mechanism) checks every proposal against formal invariants.

AXIOMIS

Our clinical intelligence system. A deterministic FHIR state machine at its core, migrating toward flexible reasoning with non-negotiable invariants.

  • Treatment plans compile to DAGs before execution.
  • Nodes are pre-flight checked by OPA/Rego policies.
  • Neural overrides require explicit symbolic justification.
