Zero Trust Architecture Implementation For A Leading FinTech Platform

We rebuilt the storefront on a mobile-first layout, so every page adapts cleanly from a 360px phone to a 4K monitor. Navigation, product grids and checkout were redesigned around thumb reach and short attention spans rather than shrunk-down desktop screens, and every breakpoint was tested on real devices.

Images are served in modern formats at the exact size each device needs, and fonts load without layout shift. Touch targets, spacing and type scale were tuned for every screen size, so nothing feels cramped on a phone or stretched on a wide monitor. The result is a site that feels native on every screen and keeps shoppers moving toward the cart.

Since launch, mobile sessions have grown to over 70% of total traffic, with bounce rates on phones dropping by nearly a third. Mobile checkout completion improved as well, helped by larger buttons, autofilled forms and express payment options. The storefront now performs as well on a small phone as it does on a desktop, which was the central goal of the project.

Beyond the storefront, we delivered a complete commerce portal covering catalogue management, customer accounts, wishlists, subscriptions and order history in one connected platform. Customers can manage deliveries, pause subscriptions and reorder past purchases in a couple of taps, without ever needing to contact the support team.

The admin side gives the team bulk product editing, bundle and discount rules, inventory alerts and role-based access, so marketing, operations and support each see exactly what they need. Scheduled price changes and campaign landing pages can be prepared in advance and go live automatically at the right moment, without anyone needing to log in and publish them manually.

Everything runs from a single source of truth, removing the spreadsheets and manual syncing the team relied on before. Stock levels, prices and customer records now update everywhere at once, so the website, warehouse and support desk always work from the same numbers. New team members can be trained on the portal in an afternoon rather than several days.

We owned the full journey, from discovery workshops and UX research through design, development, launch and post-launch optimisation, with one team accountable at every stage. Early customer interviews shaped the product structure, and clickable prototypes were tested with real shoppers before any production code was written.

Product data, payments, shipping, tax, email and customer service tools were connected into a single workflow, so an order moves from checkout to doorstep without anyone re-entering information. Automated notifications keep customers informed at every step, while the operations team sees every order's status on one live board instead of across five separate systems they used to juggle.

Weekly releases and a shared roadmap kept the client involved throughout, and the platform went live two weeks ahead of the planned date. Having a single partner for strategy, design and engineering removed the hand-offs that usually slow projects down, and gave the client one point of contact for every decision, question and change request along the way.

The platform runs on a headless architecture: Shopify handles commerce, while a Next.js frontend is deployed to a global edge network for fast, reliable delivery in every region. Separating the two means the storefront can evolve freely without putting orders, payments or customer data at risk.

Automated CI/CD pipelines, staging environments and preview builds mean every change is tested before it reaches customers, and rollbacks take seconds, not hours. Content editors can preview updates on a private link before publishing, so nothing unexpected ever appears on the live site, and developers can ship small improvements several times a day without scheduling downtime or late-night releases.

Monitoring, uptime alerts and daily backups are built in, giving the team confidence during peak sales periods and product launches, when traffic can jump tenfold within minutes. The infrastructure scales automatically to meet demand, so the client only pays for the capacity they actually use, and the site stayed online through every Black Friday and campaign since launch.

Speed was treated as a feature. We audited every page, removed unused scripts, split code by route and moved heavy work off the main thread. Third-party tags were reviewed, and anything that slowed the page without clear business value was removed or loaded only after interaction.

Critical content now renders in under a second on a typical 4G connection, and all Core Web Vitals pass across mobile and desktop. Product images load progressively, pages are prefetched as shoppers hover over links, and the checkout stays responsive even on low-powered phones. Performance budgets in the build pipeline now block any change that would make the site slower.

Faster pages translated directly into revenue: conversion rate rose by 18% in the first quarter after launch, with average order value holding steady. Paid campaigns became cheaper too, because faster landing pages earned better quality scores and lower cost per click. For the client, performance stopped being a technical metric and became one of their clearest growth levers.

Checkout supports cards, Apple Pay, Google Pay and buy-now-pay-later options, all presented in a single, distraction-free flow that works in one tap on mobile. Address lookup, saved details and clear delivery options remove the small points of friction that usually cause shoppers to leave at the final step.

Payments are tokenised and processed by PCI-compliant providers, so no card data ever touches the client's own servers. Fraud screening runs automatically on every order, flagging suspicious activity for review without slowing down genuine customers or adding verification steps they don't need. Refunds and partial refunds can be issued from the admin in seconds, with the customer notified automatically.

Failed-payment recovery emails and saved payment methods for returning customers cut checkout abandonment within the first month, recovering lost revenue. Express checkout now accounts for more than half of all mobile orders, and the average time from basket to confirmation has dropped to under a minute, making buying again as easy as buying for the first time.

Every page ships with clean semantic markup, structured product data, meta tags and an auto-generated sitemap, giving search engines everything they need to rank the catalogue. Redirects from the old site were mapped page by page, so existing rankings and backlinks carried over without any drop in search visibility.

We set up server-side analytics and a consent-aware tracking plan, so the team can follow each customer from first visit to repeat purchase without losing data to ad blockers. Every key action, from product views to completed orders, is tracked and tied back to the campaign that drove it, giving marketing a reliable view of which channels actually bring in revenue.

Custom dashboards surface the metrics that matter — traffic sources, product performance and funnel drop-off — in one place the whole team can read without needing an analyst to interpret them. Weekly automated reports land in the team's inbox every Monday, so decisions about content, pricing and campaigns are now based on real data instead of guesswork.

Launch was the start, not the finish. We provide a dedicated support team with agreed response times, proactive monitoring and a clear route for urgent issues. Most problems are spotted and fixed before customers ever notice them, thanks to automated alerts across the whole platform.

Monthly reviews look at performance, security updates and new opportunities, turning customer feedback and analytics into a prioritised list of improvements. Each month's work is planned together with the client, so development time always goes to the changes with the biggest impact on sales, and every update is documented so nothing depends on one person's memory.

The client's team was trained to manage content, promotions and products independently, so day-to-day changes never wait on developers and new campaigns can launch the same day they're planned. Short video guides and a searchable help centre cover every common task. The result is a long-term partnership that keeps the platform improving month after month.
