About Cloud Traffic
Hands-on consulting, led by a practitioner
Cloud Traffic is a boutique consultancy led by Paul Hartness, a software architect and developer who has spent his career building and running front-office and risk systems inside investment banks.
You work directly with the person doing the work. That means decisions grounded in how trading, risk, and technology teams actually operate — and code, designs, and delivery practices your own team can carry forward.
