Fractional CTO for E-commerce & Retail

Retail technology lives and dies by a handful of pressures. Peak-season scaling is the most visible: Black Friday and Cyber Monday can drive ten to fifty times normal traffic in minutes, and a platform that has never been load-tested at that scale will fail exactly when every sale counts. Caching, autoscaling, database contention, and third-party rate limits all have to hold simultaneously.

Replatforming decisions loom large. Moving to a headless architecture or off a monolithic legacy platform promises flexibility and performance, but a mistimed or over-scoped migration can freeze the roadmap for a year. PCI-DSS compliance and payment and fraud handling are non-negotiable, and the wrong integration pattern pulls your entire codebase into audit scope.

Behind the storefront, inventory and OMS integration across warehouses, marketplaces, and retail locations is where orders quietly go wrong — overselling, stale stock counts, and failed syncs. And running through all of it, conversion and performance: Core Web Vitals and page speed now directly affect both search ranking and revenue per visitor.

We begin with the calendar and the funnel. Ahead of peak, we load-test to realistic multiples, find the breaking points, and fix them — caching strategy, CDN and edge configuration, autoscaling rules, queue-based order processing, and graceful degradation so the site slows rather than collapses under pressure.

On replatforming, we bring a disciplined build-versus-buy and headless-versus-monolith framework, then scope migrations incrementally so revenue keeps flowing while the architecture improves. We reduce PCI-DSS scope by routing card data through tokenized, hosted payment flows, and we tune fraud controls to block bad actors without punishing legitimate buyers. We make inventory and OMS integration reliable with idempotent syncs, reconciliation, and clear sources of truth across channels, so a stock count is never both authoritative in two places and wrong in one.

For conversion and performance, we treat Core Web Vitals as an engineering KPI — image and asset optimization, rendering strategy, and third-party script discipline — because every hundred milliseconds shows up in the revenue numbers.

Underpinning all of it, we stand up the monitoring and alerting that turns peak season from a guessing game into a controlled operation: real-time dashboards for conversion, checkout success rate, and system health, so the team sees trouble forming and responds before customers ever feel it. We also build the runbooks and on-call discipline that keep a promotion from becoming an all-hands emergency, so the people who know the platform are not the only thing standing between a campaign and an outage.

The payoff is a retail platform that stays fast and stands up when it matters most. Peak-season events run without the all-hands firefight, because the system has been tested and hardened to the traffic it will actually see. Checkout is PCI-compliant with a narrow audit scope, fraud losses fall, and payment success rates improve.

Inventory and order data stay accurate across every channel, cutting oversells and support tickets. Faster pages lift both organic search visibility and conversion, so the same traffic produces more revenue. And when a replatforming decision does arrive, it is made with a clear framework and a migration plan that protects the roadmap — technology working for the merchant instead of against them.

Over time the whole operation gets calmer. Deployments stop being risky events scheduled around quiet hours, monitoring catches problems before customers do, and the team builds the muscle to handle growth without a crisis at every new traffic peak. The founders get back the mental space that used to be consumed by whether the site would survive the next campaign, and the business earns the confidence to run bigger promotions and enter new channels knowing the platform will hold.
