Capability areas

Systems architecture and assurance infrastructure

Architecture design for systems requiring auditability, formal provenance, and deterministic behaviour across their operational lifetime. Includes specification authoring, contract definition, and assurance-framework design for complex regulated systems.

Verifiable AI execution

Framework design, layer specification, and governance contract authoring for AI systems subject to regulatory or procurement scrutiny. Based on the Axioma verifiable AI execution framework — a seven-layer architecture for deterministic, auditable AI behaviour. Engagements are bespoke consultancy: Spey Systems Ltd does not sell Axioma as a product; it provides architecture and specification services for organisations building AI systems that must operate under audit.

Safety-critical software assurance

Technical assurance support for software operating under DO-178C, IEC 62304, ISO 26262, or similar certification frameworks. Includes design review, specification analysis, and architectural guidance for systems where correctness carries regulatory consequence.

Deterministic ML pipeline design

Pipeline architecture and review for machine learning systems requiring bit-identical reproducibility across platforms and builds. Informed by the certifiable-* open-source ecosystem — nine repositories implementing deterministic ML pipelines with Merkle audit trails.
