Production-grade web and ecommerce development for brands that need their site to behave like a real product, not a marketing artifact. Shopify Plus, headless commerce, Next.js, custom storefronts, multi-region architecture, and the performance engineering that turns traffic into revenue.
The gap between a site that demos well and a site that compounds revenue is six months of post-launch engineering most agencies never deliver. We build with that horizon in mind: Shopify Plus and headless storefronts on Next.js, instrumented from day one, sized for multi-region traffic, hardened against the long tail of bugs that quietly kill conversion. Then we keep operating it — feature releases, A/B tests, Core Web Vitals discipline, and the unsexy maintenance that separates a top-performing site from an expensive brochure.
"A storefront is the most expensive thing a brand owns and the least often treated like a real product. We treat it like one."
Custom themes, Liquid engineering, Hydrogen storefronts, B2B on Shopify, Shopify Markets multi-region, checkout extensibility, Functions for custom discounts and shipping. We build for performance, not for the demo.
Headless Shopify, commercetools, Saleor, BigCommerce, and Sanity-backed storefronts on Next.js or Remix. Edge rendering, ISR, and the architecture decisions that make headless actually faster instead of just more complex.
Full-stack Next.js applications, React component systems, design-system implementation, internal tools, customer portals, and SaaS frontends — all built with the type safety, testing, and CI discipline of a real engineering team.
Lighthouse-led performance engineering, image and font pipeline optimization, third-party script discipline, edge caching strategy, and the LCP / INP / CLS work that materially moves conversion and SEO ranking.
Multi-region storefronts with localized pricing, payments, languages, and SEO-correct hreflang. Japanese, English, Korean, Chinese, and European market support without the typical localization debt.
Conversion-rate optimization treated as a continuous engineering practice — hypothesis backlog, instrumented experiments, GA4 + server-side tagging, and quarterly read-outs against contribution margin, not vanity metrics.
We audit your current site, performance, conversion funnel, and codebase. You finish with a documented stack assessment, a prioritized opportunity list, and a build-vs-rebuild recommendation grounded in your traffic and revenue.
Platform decision (Shopify Plus, headless, custom), CMS, search, payments, analytics, deployment, and monitoring. Documented architecture, sprint plan, and a release timeline you can take to your board.
Two-week sprints, instrumented releases, weekly demos, staging gates, performance budgets enforced in CI. Launch behind a feature flag, soft-launch to a traffic percentage, then full cut-over.
Ongoing feature delivery, A/B testing program, Core Web Vitals discipline, dependency upgrades, and incident response. Engineering as a continuous service, not a fixed-bid hand-off.
A European premium beauty brand was on a sluggish Magento 2 stack with mounting maintenance debt. We replatformed to headless Shopify Plus on Next.js with multi-region storefronts for EU and Japan, a Sanity-backed CMS, edge rendering, and a server-side analytics pipeline. Lighthouse scores moved from 38 to 96, conversion lifted 102% post-launch, and the customer's monthly infrastructure spend dropped by 53%.
"Deebo are the rare engineering team that ships, instruments, and then keeps operating. The site is now the asset we expected it to be."
— Director of Digital, European premium beauty brand
