Capabilities & Services
Ways to engage us
Napkin-to-launch builds
From an idea to a production system, with the discipline that keeps it standing.
Revitalising stalled projects
Audit, stabilise, rebuild, and hand a working system back to your team.
Fractional CTO / CDO seats
Senior operating leadership, part-time, held by practising engineers.
Modernisation
Carrying old codebases forward without carrying their debt with them.
Maintenance & assurance
Keeping the systems other people's money depends on, running and honest.
Technical Turnarounds
Most failing projects do not lack effort. They lack a precise account of what is wrong, and a frugal plan to fix it. We provide both.
- Architecture Audits — a two-week, fixed-scope review from a systems perspective: architecture, dependencies, delivery process, infrastructure. Every finding rated critical, high, medium, low, or well-done.
- Deep Code Review — line-by-line reading of the code itself, every finding referenced to the specific lines. A larger engagement, priced separately.
- Stabilisation & Remediation — stabilise first, then rebuild the execution paths the report condemns.
- Process Reboot — delivery measured against the industry's standard performance metrics, run with continuous integration, exhaustive monitoring, and load-tested capacity planning.
- Handover-Ready, Always — every action traceable, every decision recorded, documentation written for the team that will own the system next.
Recent: a platform two years behind schedule, shipped in seven months. See the Track Record.
Executive Leadership
For founders and boards that need executive technology leadership without the full-time headcount. We have sat in the seat: CTO-level technical leadership of teams of a hundred engineers, across fintech, blockchain, healthcare, and regulated enterprise software.
Fractional CTO — the "how"
Ownership of the stack, the velocity, and the reliability: architectural direction, mentoring your lead engineers, delivery metrics, and hiring guidance.
Fractional CDO — the "what" and the "why"
Engineering aligned with the business: which products to build, which digital assets create enterprise value, and how to sequence and price the work.
Regulated & Financial Systems
Production work in regulated domains: pharmaceutical computation, trading platforms, DeFi protocols, and reinsurance ledgers.
- Correctness-first delivery — invariants stated before code, verified by property-based tests and fuzzing, reviewed line by line.
- Financial modelling first — when a platform is two years late, the model is usually wrong before the code is. We fix the math, then the architecture.
- Audit-grade rigour — the ranked-findings discipline of our correctness reviews, applied to systems where correctness matters.
AI-Augmented Engineering
Model output is stochastic and non-deterministic. Left unchecked, it compounds hidden technical debt.
Our answer is structural, not promptural: small units of work with acceptance criteria; property-based tests and type invariants as the guardrails the agent must satisfy; evals that score generated code before it merges.
We measure trajectories, not vibes. Value shipped versus hidden debt, review latency, defect escape rate — reported continuously.
Every merged line is accountable to the partner whose name is on the engagement.
High-Assurance Systems
- Type-Driven Development — the type system carries the invariants, eliminating whole classes of error before the code runs.
- Property-Based Testing & Fuzzing — tests that state what must always be true, then try to break it.
- Security & Correctness Reviews — line-by-line reading plus tool-assisted scanning, findings ranked critical to well-done.
- Multi-Cloud Platform Engineering — a platform of roughly one hundred worker nodes across two clouds, upgraded and recovered without interruption.
- Distributed Systems & Infrastructure — high-throughput message routing, infrastructure-as-code, fully automated build, test, and deploy.
Training & Enablement
We teach teams what we know. Our engineers have written the published books and training programmes that working engineers learn practical typed functional programming from — and we bring that teaching into every engagement, so your team is stronger when we leave than when we arrived.
