Melbourne & Brisbane · Australia-wide · since 2010
Business systems, customer platforms and native apps, engineered the way good software has always been engineered, and delivered on a foundation that is already running in production.
Anyone can generate version one now. Good software was never about the first release. We build the system you will still be glad to own in year five.
What we build
Not brochure sites, and not the quick builds an AI subscription can produce on its own. The systems an operation depends on: the domain model, the data, the security, the integrations, the screens on the web and in people’s hands, and the infrastructure that keeps all of it running.
The operational core of an organisation, shaped around how it actually works: bookings, case management, finance, scheduling, approvals, reporting. For organisations that have outgrown spreadsheets and off-the-shelf tools, or were about to fund a team of ten to forty developers to build it in-house.
Domain modelling · event sourcing · full audit history · live dashboards · role-based access
Multi-tenant products sold to many customers, with payments, subscriptions, identity, notifications and integrations built in from day one. For founders, we build it and host it as a turnkey service for a known, fixed price, on a foundation you can see running other software before you commit.
C# / .NET 10 · TypeScript · SvelteKit · PostgreSQL · typed real-time · Stripe · single sign-on
iOS and Android apps that share the platform’s contracts, so the screen in a customer’s hand cannot drift from the server behind it. Check-in, scanning and field tools for staff, alongside the apps your customers use.
iOS · Android · Swift · Kotlin · generated client contracts
The systems that have already become expensive to change. For the last decade our job has often been to be the people brought in to fix the early decisions in someone else’s project. A fifteen-year production platform was rebuilt from the ground up and cut over onto a new stack, with a live user base throughout and every record kept.
Data migration pinned by tests · staged cut-over · Azure · AWS · Linux containers
Why now
Every new product trades speed for quality. Ship now, fix later, and later arrives as a rewrite. Those early decisions are rarely made by amateurs. They are made by capable developers, earlier in their careers, under pressure to deliver. We know, because fixing them has been a large part of our work.
Now everyone can generate code. Version one has never been cheaper, and the gold rush is real. An agent is fast, tireless and fluent, and confidently wrong when nobody who knows what good looks like is reading the result. The leverage has moved from the size of the team to the direction of the work.
So we put the agents in the outer ring. At the centre sit senior architects and a foundation written once, and protected: security, data, messaging, deployment. Every pattern that matters lives there, so it is done one way, everywhere. Analysers, generated contracts and tests stop a bad change at the build, not in review. Agents write. Senior people read, approve, and answer for what ships.
The same arithmetic changes who enterprise software is for. A system that would have been quoted in the millions five years ago is now within reach of a government department, a regional business, or a family company that has outgrown its spreadsheets. The real thing, not a prototype, and handed over in your control when you want it.
Real engineering, accelerated. The tooling changed. The engineering did not.
Working with us
Every option starts on the same proven foundation. You choose how much of it you hold.
A known, fixed price for the build, then we host and manage it for a monthly fee. You run the business; we keep the software running: the infrastructure, the databases, the backups, the certificates, the pipelines and the phone call at three in the morning. We have done exactly that for our own platforms for the better part of fifteen years.
We build it, help you hire and train your own engineers, and license the foundation so you own it and run it on your own infrastructure. Start turnkey and take over when you are ready, or take the handover straight away.
We ship and manage the core product. Your developers build the features particular to your business through a clean, supported seam: a REST API, webhooks, embedded pages and sandboxed plugins. Extensions cannot reach past the seam, so your changes never break what we maintain, and nobody argues about whose bug it is.
Our two longest-running platforms are partnerships: the business partners brought the idea, the domain and the market, and we brought the ability to build it and keep it running. If the idea is good enough, we may partner with you rather than charge for the build.
Enterprise solutions
Enterprise systems that once took a team of thirty and cost millions can now be delivered for a six-figure amount. The saving does not come from a thinner scope or a cheaper team. It comes from starting on the eighty per cent every business system needs, already built, already tested and already in production, so the budget goes on what is particular to your operation. Not everyone needs enterprise security; for those who do, you are fully covered.
Our own single sign-on (OAuth 2, OpenID Connect), two-factor authentication and passkeys, one permission model enforced on the server, managed and rotated keys, encrypted offsite backups, and TLS everywhere. Your identity provider, key vaults, private networks and compliance regime, configured to order.
Pure decision logic over an immutable event history. The same input always gives the same answer, every change carries a full audit trail, and business rules are tested in milliseconds. The foundation carries more than 35,000 automated tests.
The same containers and the same automated deployment on any cloud provider or on your own servers. Bespoke security, audit and data-residency requirements for finance, health and government. Self-hosted software you own, if that is what the regulator asks for.
A new regulation, an acquisition, a partner with their own systems. Separated services, typed contracts and every vendor behind its own seam mean a new requirement is a change in one place, not a rewrite. Payments, CRM, messaging and AI models plug in and swap out.
Funding an in-house team, outgrowing your tools, or replacing a system that has become expensive to change? Book a free consultation, and we will tell you plainly what it would take.
In production
It is not just code that is shared. Containers, deployment, testing, the front end, the back end and the wiring between them are common, and every application that ships hardens the foundation for the next. It already runs a charity’s operational system on live data. In development on it: a multilingual health product on web and mobile, and our flagship, yourtickets.ai, version 3 of tickets.org.au.
tickets.org.au has sold hundreds of thousands of tickets for community, not-for-profit and ministry events since 2017. Version 3 is a ground-up rebuild on our foundation, due at the beginning of 2027, carrying the years of records forward.

15 years
continuous
Both have stayed live for the better part of fifteen years, in production since 2011 and 2015. One serves over 10,000 registered users, with personal data behind a login. The other has sold hundreds of thousands of tickets. Compute, databases, storage, networking, DNS and TLS, backup and restore, capacity, release, and incident response have remained with this practice for the life of both. Both operate under the Australian Privacy Principles.
2 years
enterprise
Linux containers, Service Bus, Cosmos DB, Event Hubs, and Service Fabric, with Log Analytics, KQL, and Datadog, at a scale where a latency regression is measured in money. The work sat inside a large organisation’s governance. Hosting cost came down by profiling and rewriting the slow paths.
Inception to
hundreds of
customers
Technical design and lead development of a SaaS product from first commit through to hundreds of large corporate customers — banks, airlines, universities, and government departments — handling commercially sensitive data. CQRS and event sourcing on .NET and PostgreSQL, with the team recruited and coached along the way.
~1,500
commits
A ground-up rewrite onto .NET 10 and PostgreSQL, running as containers on Ansible-provisioned Linux behind Caddy, with one deployment pipeline serving three products from shared base images. The data migration was pinned by tests against real production records, with explicit partial-failure reporting. Most of the code was written by directing AI agents under close architectural direction, on practices that keep a codebase reviewable: pure domain logic, fast tests, and rules enforced in the structure.
Regulated &
government
A major business-intelligence programme delivered into a large federal government department. Government departments among the customers of the platform above. Work to formal change control across betting, legal, and enterprise settings. Against the Essential Eight, managed patching, multi-factor authentication, restricted administration, pinned images, and daily backups with tested restores are standard practice here.
Across
the years
Enterprise client portals, integrated accounting, national supply-chain and B2B integration, and mobile applications shipped to both stores from one codebase. Master-data leadership through a group-wide ERP transformation. The measure of that work is that it kept running.
