Web & Mobile

Ship software your team can actually hand over.

We design and build fast, accessible products on a modern stack (Next.js, React Native, TypeScript, Postgres). No black-box CMS, no template traps, no five-agency hand-off. The site or app you ship is clean code your team can maintain.

What's included

01

Marketing site

A bilingual, SEO-strong marketing site on Next.js with a proper CMS behind it. Page-speed budgets and Core Web Vitals baked in from the first commit.

02

Web platform

Auth, roles, dashboards, payments, file uploads — the connective tissue between your customers and your ops. API-first so it plugs into what you already run.

03

Mobile app

Cross-platform React Native apps with offline support, deep links and push notifications. One codebase, iOS + Android + web, with native performance where it matters.

04

Ecommerce

Headless stores on Shopify or a custom Stripe + Postgres stack. Tight brand control, sub-second page loads, and a product team that can move without waiting on us.

05

Integrations & APIs

REST / GraphQL / tRPC APIs, webhook plumbing, third-party integrations (CRMs, payments, calendars). Typed end-to-end so refactors are safe.

06

Performance & SEO audit

A 2-week diagnostic on an existing site — Core Web Vitals, accessibility, crawl issues, content architecture — with a prioritised fix plan you can hand to any team.

How it runs

  1. 01

    Discover

    Stakeholder interviews, review of existing systems, a plain-English spec and a decision on the stack. Success metrics agreed on paper before anyone opens a code editor.

  2. 02

    Define

    Architecture, data model, Figma for key screens, and a roadmap with weekly milestones, a clear budget per phase, and acceptance criteria for launch.

  3. 03

    Design & Build

    Weekly sprints against a live staging URL from day one. You review working software — not PDFs. Accessibility, SEO and performance are built-in, not bolted on.

  4. 04

    Launch

    DNS cutover, analytics, error monitoring, uptime alerts, and a runbook your support team can actually use. Two weeks of hypercare with the staging URL kept as a rollback target.

  5. 05

    Grow

    Monthly retro: performance audits, SEO improvements, A/B tests and feature experiments. Structured iteration against the metrics we agreed at the start.

A good fit for

Rebuilding a slow, outdated marketing site

You ranked well five years ago, Core Web Vitals punish you now, and editing a page requires a developer. We rebuild with a CMS your team can run.

Launching a product MVP before hiring a team

Validate an idea with real users on a small, production-grade codebase that a future in-house team can take over without a rewrite.

Adding a customer portal to a services business

Auth, a dashboard, file uploads, and an admin — the connective tissue that moves you from email attachments to a real product surface.

Turning a spreadsheet workflow into software

You're running a business on a shared Google Sheet and it's breaking. We ship a purpose-built tool with the logic already in your head, not a generic SaaS that forces a rewrite of your process.

Frequently asked

What stack do you use?

Next.js / React / TypeScript on the frontend; Node + Payload or a custom Postgres backend; Stripe for payments; React Native for mobile. We pick boring, battle-tested defaults — no framework-of-the-month.

Who owns the code?

You do. Source in your GitHub/GitLab from day one, credentials in a shared vault, and documentation written as we go. We build to hand over, not to hold hostage.

Do you do SEO?

Technical SEO — performance, crawlability, schema, hreflang, sitemaps — yes, always, built in. Content strategy and link-building we can advise on but we don't ghost-write.

Can you work with our existing design / backend?

Often. We can plug a new frontend onto your existing API, or bring your Figma into our build process. A one-week audit at the start tells us (and you) what's realistic.
