What we build.

Six things, and the stack behind each. Where we have shipped something that demonstrates one, it is linked. The work is the argument.

01

Web applications

The core of the studio: applications that carry a business's daily operations.

We build full-stack applications from the first conversation through to running in production, covering architecture, implementation, release, and the work of keeping it up. That includes the parts nobody demos: authentication, permissions, and databases that stay fast as the data grows.

Sound familiar?

The business runs on a spreadsheet one person guards and three tools that do not talk to each other. Every new feature waits on the only developer who understands the code, and each release is a risk nobody has time to take.

What that takes

  • Full-stack applications

    One team from the data model up to the interface, so the decisions made in the database are the ones the screen was designed around.

  • Secure APIs and authentication

    Sign-in, sessions and permission checks written once and enforced on the server, never left to a hidden button in the interface.

  • Dashboards and admin panels

    The internal screens a team lives in: search, filters, bulk actions, and the reports someone opens first thing every morning.

  • High-performance databases

    Schema, indexes and queries designed for the volume you expect to reach, not the volume you have on launch day.

What you get

  • An application running in production, with the source in a repository you own
  • Authentication, roles and permissions enforced on the server
  • An admin panel your team can use without asking a developer
  • A database schema and queries built to hold their speed as data grows
  • A handover walkthrough of how the system fits together

02

E-commerce

Storefronts and the systems behind them, custom or on a platform.

We build commerce as a custom application when the catalogue or the workflow needs it, and on Shopify or WordPress when it does not. The decision is made on what you are selling and how you operate, not on what we would prefer to build.

Sound familiar?

You are selling through a theme that nearly fits. Variants need a workaround, the catalogue is bigger than the template expected, and changing one thing about an order means paying for another plugin and hoping it holds.

What that takes

  • Custom commerce builds

    A storefront and order system written from scratch when the catalogue, the pricing or the fulfilment workflow is too specific for a theme to carry.

  • Shopify and WordPress storefronts

    Platform builds where the platform is genuinely the right answer, set up so your team can add products and pages without opening a ticket.

  • Landing pages and business websites

    Responsive pages for a launch, a campaign, or a company that needs a site which loads quickly and reads well on a phone.

What you get

  • A live storefront on whichever platform the work actually called for
  • Product, variant and collection management your team runs themselves
  • Checkout wired to a payment provider and tested end to end
  • Layouts checked across phone, tablet and desktop widths

03

Mobile applications

One codebase, both platforms, shipped to the stores.

Cross-platform builds in Flutter and React Native, taken through to release on iOS and Android. Native work where a cross-platform framework would fight the problem rather than solve it.

Sound familiar?

You need to be on iOS and Android out of one budget. Writing the app is only half of it. Signing, listings and review are the half that quietly stalls a launch, and so far nobody has owned them.

What that takes

  • Flutter builds

    Our default when the interface is the product: a single codebase and a widget layer that follows the design rather than the platform's defaults.

  • React Native builds

    The right call when a React web app already exists and you want logic, types and developers shared across all three targets.

  • Native Android and iOS work

    Dropping to the platform itself for the parts a cross-platform framework would fight rather than solve.

  • Store release

    Builds signed and taken through submission and review on both stores, so the app finishes on a device rather than in a folder.

What you get

  • Signed release builds submitted to the App Store and Google Play
  • One codebase covering both platforms
  • Store listing assets prepared and the review process seen through
  • The app running against a live back end, not a mocked demo

04

Custom CRM and automation

Internal tools for the work that is currently being done by hand.

Custom CRMs with role-based access, lead routing, and the operational reporting a team actually opens each morning. Where a process is repetitive and rule-based, we automate it rather than build a screen for someone to sit in front of.

Sound familiar?

Enquiries land in a shared inbox and get picked up by whoever notices first. The same figures are rebuilt by hand every Monday, and the whole process holds together because one person remembers the order of the steps.

What that takes

  • Custom CRM

    A system shaped around how your team actually sells and supports, with role-based access so each person sees the records that belong to them.

  • Lead routing

    Enquiries captured and assigned by rule rather than by whoever is nearest, then tracked through to what happened to them.

  • Operational reporting

    The daily and weekly numbers built into the tool itself, so no one exports to a spreadsheet to answer a standing question.

  • Workflow automation

    Repetitive, rule-based steps handled by the system: status changes, scheduled jobs, and the handoffs between the tools a process already crosses.

What you get

  • A CRM your team signs into, with roles and permissions already set up
  • Automated routing and status rules replacing a manual step you can name
  • Reporting views covering the questions the team asks every week
  • Connections between the tools the process runs across

05

AI integration

Language models wired into a product, with the evaluation to know they work.

Retrieval systems over your own documents, model evaluation, and prompt work that is version-controlled rather than pasted into a text box. We integrate AI where it changes what the product can do, and say so when it would only change how it is marketed.

Sound familiar?

You have been asked to put AI in the product. What exists is a prompt someone pasted into a text box: convincing in a demo, awkward in front of a customer, and impossible to say whether the next version of it is any better.

What that takes

  • Retrieval over your documents

    Your own material indexed and searched so answers are grounded in what you actually published, and can be traced back to the page they came from.

  • Model evaluation

    A fixed set of cases the feature is scored against, so changing a prompt or a model becomes a measured decision instead of an impression.

  • Version-controlled prompt engineering

    Prompts kept in the repository with the rest of the code: reviewed, diffable, and tied to the release that shipped them.

  • Product integration

    The feature built into the flow a user is already in, with defined behaviour for the moments the model is unavailable or plainly wrong.

What you get

  • A retrieval pipeline over your own documents, with sources shown alongside answers
  • An evaluation set and scores you can re-run after any change
  • Prompts held in version control with the application code
  • Defined behaviour for when the model fails or is unavailable

06

Design and branding

Interface and identity, for teams without a designer.

UI design for the applications we build, and the branding assets that go around them: logos, marks, and the basic system that keeps a product looking like one thing. Available on its own, not only as part of a build.

Sound familiar?

There is no designer. The product was assembled screen by screen as each one became urgent, the brand is a logo somebody made once, and every new page turns into an argument about what it should look like.

What that takes

  • Interface design

    Layout, type and the states around a screen, drawn by the people who will build it so nothing arrives that the data cannot support.

  • Branding and identity

    The marks, colours and type choices that make a company look like one thing across a site, an app and a document.

  • Logos

    A primary mark plus the variants a working business needs: small, single-colour, on a dark ground, and down to a favicon.

What you get

  • Designs for the screens and for the states around them
  • A logo with variants for light, dark and small sizes
  • A colour palette and type scale the build uses directly
  • Source files handed over at the end
