Services
What we build for clients
Everything below, we do for our own products too. You get the same team, the same stack, and the same standards we hold ourselves to.
-
Web Applications
Responsive web apps built on conventional, well‑documented stacks. PHP, TypeScript, PostgreSQL, the usual.
-
SaaS Platforms
Multi‑tenant systems with real role‑based access, workspace isolation, audit trails, and an honest admin back end.
-
APIs & Integrations
REST APIs for your own teams, plus thoughtful integrations with the vendors your business already depends on.
-
Payments & Billing
Stripe‑backed subscriptions, metered usage, invoicing, refunds, dunning. Connected to your accounts, not ours.
-
Hosting & Operations
Managed hosting, monitoring, backups, incident response. Most studios ship and leave — we stay.
-
Product Strategy
Shape of the thing before the code. Scope, pricing, MVPs, and roadmaps informed by running our own products.
Work
Products we own and operate
Six live products, all designed, built, and run in‑house. Every one pays for itself — the product page and pricing are linked from each card.
SupportLayer
Helpdesk software for teams that need clear ownership, SLAs, and role‑based permissions instead of a shared inbox. Isolated workspaces, pausing SLAs, MFA, controlled attachments, and a full audit trail.
supportlayer.appProjectLayer
Cloud‑based project management for developer teams. Kanban, tasks, milestones, releases, and a REST API. Native SupportLayer integration turns tickets into tasks in one click.
projectlayer.appResortStrata
Cloud‑hosted operations software for multi‑unit resorts, strata schemes, and timeshare. Occupancy with overlap checks, servicing, maintenance jobs, and owner invoicing via your own Stripe account.
resortstrata.comCoorieControl
Bespoke home automation for UK homes — smart heating, app‑based control, curtains and blinds, load switching, and custom integrations. Built and adapted around each property.
cooriecontrol.comUtilhub.dev
A curated collection of browser‑based developer utilities and practical how‑to guides. Fast access to everyday tools — processing happens locally, nothing leaves the tab.

Approach
A five‑stage process that doesn't end at launch
Every engagement follows the same shape. The fifth stage is where most studios drop off — and where our work actually pays back.
-
01Week 1
Discover
Workshop, map the domain, and agree on success. No slideware — a one‑page brief you can actually check work against.
-
02Weeks 2–3
Design
Interactive prototypes in the real browser. We skip static mocks for the important screens — it saves weeks downstream.
-
03Weeks 3–10
Build
Small, frequent releases to a staging environment you can poke at. Tests, CI, code review. Legible code, kept legible.
-
04Week 10+
Ship
Production launch with monitoring, backups, and on‑call in place before the first real user arrives. A soft launch if you want one.
-
05Ongoing
Operate
The long tail: incidents, migrations, iterations, and the unglamorous upkeep that separates a working product from an abandoned repo.
