Practical engineering for critical financial systems
Architecture, development, and delivery support for trading, risk, and payments systems — scoped to the problem in front of you and focused on outcomes your team can sustain.
Architecture & platform design
Target architectures for trading and risk platforms that hold up under real desk, regulatory, and operational pressure.
Independent architecture reviews and hands-on design for trading, pricing, and risk systems — including vendor platforms such as Sophis, in-house pricing libraries, and the integrations that connect front office to middle office and finance.
What good looks like
- A documented target architecture the team understands and can build towards
- Clear boundaries between pricing, booking, risk, and reporting components
- Integration patterns that keep vendor upgrades and library releases manageable
- Risks and trade-offs made explicit before they become production incidents
Front-office & risk development
Pricing models, desk tools, and risk extraction pipelines built in C++, C#, and modern stacks.
Senior engineering on the code that matters most to the business: pricing models for derivatives products, front-office tooling for traders and structurers, and high-volume data extraction feeding risk and P&L.
What good looks like
- Pricing and risk code that is tested, reviewed, and traceable to requirements
- Data extracts that finish inside the batch window and reconcile first time
- Tools that traders and risk managers actually use day to day
- Code a permanent team can own and extend after the engagement ends
Modernisation & continuous delivery
Incremental modernisation of legacy financial systems and the CI/CD practices that make releases routine.
Practical modernisation that avoids big-bang rewrites: automated builds and tests around existing systems, staged migration of high-risk components, and release pipelines that satisfy change-control without slowing teams down.
What good looks like
- Every change built, tested, and packaged automatically
- Smaller, more frequent releases with clear audit trails
- Legacy components retired in planned, reversible steps
- Less time spent on manual release coordination and weekend deployments
Payments & revenue infrastructure
Design and review of payment flows, billing integrations, and the failure handling that protects revenue.
Advice on payment and subscription billing infrastructure, from provider integration and reconciliation to retry and recovery logic for failed payments — informed by building and running RetryFix, our own payment recovery product.
What good looks like
- Payment flows that handle failures, retries, and edge cases deliberately
- Reconciliation between payment providers, billing, and finance records
- Visibility of revenue at risk from failed or disputed payments
- Integrations that respect the security and compliance obligations involved
Delivery leadership & coaching
Leadership for development teams working in regulated, multi-site environments.
Interim technical leadership or coaching for team leads and managers: setting engineering standards, structuring delivery across locations, and building the working relationship between development, the desk, and control functions.
What good looks like
- A predictable delivery rhythm stakeholders can plan around
- Shared engineering standards across distributed teams
- Engineers who understand the business context of what they build
- Smooth hand-over to permanent leadership
Ways to engage
Flexible, clearly scoped engagements
Every engagement starts with a conversation about the problem, the constraints, and what success looks like.
Architecture review
A fixed-scope assessment of a system or proposed design, with written findings and a prioritised set of recommendations.
Hands-on delivery
Embedded senior engineering or technical leadership for a defined project or phase of work.
Ongoing advisory
Regular, lightweight access for design reviews, hiring support, and a second opinion on key technical decisions.
Have a system that needs designing, rebuilding, or shipping more reliably?
Start with a short, no-obligation conversation about where things stand and what a useful first step would look like.
