James Carter

Software Architect & Tech Lead

London, United Kingdom

I’m James — a software architect with 12 years of experience designing systems that stay fast under real-world pressure.

I specialise in FinTech and core-banking platforms: from event-driven microservices to rock-solid audit trails that regulators love.

Focus: distributed systems, domain-driven design, performance budgets

Boring architecture, exciting results. If a system needs drama, it wasn’t designed right.
