Fractional CTO
for E-commerce Agencies

Technical leadership for agencies where platform decisions have direct revenue consequences.

E-commerce agencies build the platforms that clients' revenue depends on. Performance, reliability, and scalability aren't differentiators — they're baseline requirements. And the move to headless commerce, composable architecture, and AI-driven personalisation is accelerating faster than most agency tech practices can keep up with. A fractional CTO brings the architectural experience to make those decisions well — before they become expensive to fix.

Where I help most

The problems e-commerce agencies hire a fractional CTO to solve.

01

Headless and composable architecture decisions

Clients are being sold headless commerce without understanding the long-term maintenance cost. A fractional CTO evaluates the real trade-offs — performance gains, build complexity, ongoing ownership — before you commit to an architecture you'll be living with for years.

02

Platform selection

Shopify Plus, Commercetools, VTEX, BigCommerce, custom builds. Each has a different cost profile, scalability ceiling, and developer ecosystem. Getting this wrong costs clients hundreds of thousands to fix — and costs you the relationship.

03

Peak traffic and reliability

Every e-commerce client has a peak period. Designing for Black Friday throughput, setting up load testing, and reviewing deployment pipelines before the sale — not after — is the kind of technical leadership that protects your most important client relationships.
