About
Paul Hartness
Software architect and developer with extensive experience building trading, pricing, and risk systems in the financial sector.
Architecture and delivery, from the front office outwards
Paul Hartness founded Cloud Traffic Ltd to give financial institutions direct access to senior, hands-on engineering expertise. His background spans solution architecture, front-office development, and team leadership, including serving as Solutions Architect and Front Office Development Manager for the equity derivatives platform at Standard Chartered Bank.
He has written C++ pricing models for revenue-generating equity derivatives products, designed high-performance data extraction from Sophis into middle-office risk systems at BNP Paribas Fortis, and introduced continuous integration and delivery to front-office teams working under bank change-control.
That combination — deep familiarity with how desks, risk, and technology teams work, alongside current engineering practice — is what Cloud Traffic brings to every engagement.

Approach
How we work
Helping teams ship reliably matters as much as getting the design right.
- Clean architecture
- Clear boundaries and simple designs that teams can reason about, test, and change safely.
- Continuous delivery
- Automated builds, tests, and releases so that shipping is routine rather than an event.
- Built for regulated environments
- Delivery that works with change-control, audit, and risk functions instead of around them.
- Hands-on and accountable
- You work directly with the person doing the work, from first conversation to hand-over.
