Why Coder71

Built like a product team, priced like a partner.

Four commitments in every contract — not just on the website.

Senior engineers only

The people who scope your build are the people who write it.

Scope stated in writing

A written scope with the risks named, and a free consultation before it. No mystery quotes.

You see everything

Board access and a staging link from the first sprint, in your timezone's overlap hours.

We stay after launch

Maintenance, CRO and SEO handled by the team that built the store.

How we work

Discovery to launch, step by step.

You get the board and the staging link from the first sprint, whatever the scope turns out to be.

  1. Discover

    We audit the current store, map the catalogue and every integration, and agree the architecture — which framework, which database model, what has to be migrated. You leave this stage with a written scope and a named risk list.

  2. Design

    User flows and interface design worked through against your real catalogue, including the edge cases a template never shows. Nothing is built until you have approved what it will look like.

  3. Build

    Storefront, commerce API and admin engineered in reviewable increments, with a staging link you can open at any point. You review working software rather than slide decks.

  4. Integrate

    Payments, tax and duty, ERP, 3PL and analytics connected and reconciled against real orders rather than sample data. Each integration is proven with live test transactions.

  5. Launch

    Redirects, structured data and performance verified, then a cutover rehearsed against a clone of production. Launch day is a repeat of something we have already done.

  6. Support and grow

    Defects fixed under warranty, then maintenance, conversion work and SEO with the same engineers. The team that built the store is the team that answers.

Proven expertise across multiple sectors.

No matter the industry, the approach is the same — understand the challenge, build the right thing, and ship results that hold. We have taken brands in retail, beauty, B2B and more from idea to launch.

Fashion & apparel

Variant-heavy catalogues, with sizing and returns that behave.

Health & beauty

Refills, bundles and subscriptions that keep customers.

Food & grocery

Quantities, delivery slots and stock that stays honest.

B2B & wholesale

Tiered pricing, quotes and account-based ordering.

SaaS

Plans, usage limits and billing wired into the product.

Agencies

White-label build capacity, shipped under your brand.

Technology

Tools we ship with.

Quote on Monday, kickoff the next week, launch on the date they named. That's rare.

FAQ

Questions we get on every call.

Find the right solution for you now.

Free 30-minute technical call. No sales deck.

Book a call

It depends on scope, and we would rather say that than publish a number your project then contradicts. What moves it: how large and how complex the catalogue is, how many systems have to be integrated, whether you are migrating an existing store or starting clean, how much of the design is bespoke, and how much of the business logic the platform cannot already express.

Send a paragraph describing the store and what is wrong with it. You get a technical response with scope, the risks we can see, and a written proposal — at no cost, and with no obligation to proceed.

Next step

Tell us the goal. We’ll scope the work.

New website, a rebuild, Shopify, a mobile app, custom software or SEO — one paragraph is enough. You get scope, risks and a timeline back within one business day, from the engineer who would build it.
