Engineering services

Deterministic verification, test audits, and CI/CD pre-merge protection.

We eliminate vacuous assertions in AI-generated code, mathematically prove test resistance against synthetic faults, and install continuous pre-merge gates.

Service areas

Three engineering service lines.

Domain Invariant Engineering

How the verification method works

Modern cloud and distributed systems fail when complex state transitions, authentication boundaries, and data validations lack strict invariant specifications.

How we take it on

We engineer deterministic invariant boundaries into core software services, validating state transitions and domain assertions before changes reach production.

What stays with your team

Working software with verified invariant specifications: review records your team can inspect, verified domain assertions, and acceptance evidence for every delivered change.

Quality Engineering & Test Audit

Explore Pramāṇa audit engine

AI-assisted coding expands test coverage while release regressions persist. Copilot and Cursor generate test suites that pass CI by asserting shallow matchers (such as toBeDefined), mocking essential dependencies, and skipping domain error branches, leaving critical regressions undetected.

How we take it on

Pramāṇa audits AI-generated test suites for assertion gaps, mock tautologies, and unasserted error branches. We rewrite assertions against domain invariants, replace vacuous matchers with strict value checks, eliminate paper shields, and install automated pre-merge gates in CI to prove fault resistance on every pull request.

What stays with your team

An AI test audit report documenting false-confidence rates, unasserted domain branches, and vacuous matchers. Handover includes corrected fault-resistant test suites, verified invariant assertions, faster CI runs, and an automated pre-merge verification gate with a traceable record.

Platform Reliability & CI Gates

Retail platform technical provenance

Traffic growth, system changes and incidents expose weaknesses that day-to-day operation hides.

How we take it on

We start by mapping services and delivery paths, then fix weaknesses in order of consequence. We review every change against strict gates, and the map stays with your team after handover.

What stays with your team

The records your team needs to operate and audit the platform: the service and delivery map, a rollback procedure rehearsed during the engagement, and change and incident logs kept independently of any tool's own reporting. AI tooling holds no production credentials, and that control is in writing.

Delivery model

Deterministic verification, dedicated delivery units.

Every engagement operates against an agreed scope, deterministic acceptance criteria, and an auditable review record. Product, quality, and platform engineering capabilities follow the work.

You always know who is working and on what. The engagement proposal names each engineer and specialist with their role, credentials, and responsibilities, and substitutions require client approval. At handover you receive the code, configuration, review record, operating notes, and open risks.

A named principal engineer approves the scope, the review record and the handover for every engagement.

AI tools assist the engineers and never occupy an engineer slot. The engagement record logs where they were used.

Published research and official upstream release notes inform how we test, review and deliver.

The engagement arc: the controls installed in week one, the loop every change runs through, and what stays with your team at handover. Follow one change through the loop.

Specialist systems

Specialist systems engineering.

Our engineering delivery units provide specialist capability across distributed systems, cryptographic security, and high-concurrency runtimes.

Decentralised Systems

Blockchain & Distributed Ledgers

Multi-party data coordination, cryptographic state replication, and smart contract boundaries. We model transaction invariants, validate consensus parameters, and deliver verifiable audit trails integrated directly with existing systems.

Delivered under: Product development

Quantum Security

Quantum-Ready Cryptography

Auditing existing public-key infrastructure and introducing crypto-agility layers. We implement NIST-standardized post-quantum algorithms (ML-KEM and ML-DSA) to future-proof long-retention archives against harvest-and-decrypt risks.

Delivered under: Platform reliability

Resilient Scale

High-Throughput Concurrency

Deploying BEAM/Erlang, Elixir, and Rust runtimes for high-volume message passing and low-latency state engines. We design supervisor trees and fault-isolated actor systems that deliver predictable throughput under extreme workload spikes.

Delivered under: Quality engineering

Commercial engagement

Engineering verification engagements.

A dedicated senior engineering unit for product development, quality engineering or platform reliability. Pricing is from £18,000/month, quoted per engagement.
