11Service · Web & Ecommerce Development

Web that ships,performs, and converts.On the timeline you actually have.

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.

Most websites are built by agencies. Few are operated by them.

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."

Capabilities

What this engagement actually includes.

Shopify Plus development

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 & composable commerce

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.

Next.js, React & web app development

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.

Performance & Core Web Vitals

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 & multi-language

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.

CRO, A/B testing & analytics

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.

Process

How we run the work.

01Audit

Stack & opportunity audit

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.

2 weeks
02Architect

Stack selection & technical design

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.

3-4 weeks
03Build

Sprint delivery & launch

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.

8-16 weeks
04Operate

Always-on engineering retainer

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.

Ongoing
Case study · European brand replatforming for Japan + EU

Headless Shopify replatform that doubled conversion and halved infra cost.

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%.

Why Deebo

Three reasons clients choose us for this.

01

We are an engineering team, not a deck team.

Senior engineers in Tokyo and London with named ownership of every project. No junior left alone with a Figma file and a deadline.

02

We optimize for the second year, not the launch party.

Our builds are documented, observable, and handover-ready from day one. You inherit a maintainable codebase, not a black box.

03

We treat performance and conversion as one practice.

Performance engineering and CRO live on the same team. The improvements compound — faster site, higher conversion, better SEO, lower CAC.

FAQ

Honest answers to honest questions.

Do you only build on Shopify, or do you also do custom?

+
Both. About 60% of our web builds are Shopify Plus or headless Shopify on Next.js, where the platform's strengths actually fit the brand. The rest are custom Next.js or Remix applications, headless commerce on commercetools or Saleor, or BigCommerce where B2B requirements warrant it. We make the platform call against your category, scale, and roadmap — not against our defaults.

Can you take over an existing build from another agency?

+
Yes — about 40% of our engineering retainers begin as takeovers. We run an honest audit, document what's salvageable, and quote a stabilization sprint before any feature work. No surprises, no rip-and-replace by reflex.

How do you price web development engagements?

+
Discovery and architecture are fixed-fee. Build phases run as monthly sprint capacity (typically 2-6 engineers plus a tech lead). Ongoing operations is a predictable monthly retainer. Scope changes are quoted explicitly, not buried in change orders.

How quickly can you start, and how soon can we launch?

+
Most engagements start within 2-3 weeks of contract. A Shopify Plus replatform typically launches in 10-14 weeks. A custom Next.js storefront with headless commerce typically launches in 14-20 weeks. We give you a binding date at the end of the architect phase, not in the pitch.
