Custom Development
Web apps, APIs, mobile apps, ecommerce, and Atlassian Marketplace plugins. We write the code, set up the infrastructure, ship it, and stay on for support.
Overview
Software works because it solves the right problem. We start by understanding your business, then build it properly — concept, architecture, deployment, and the long tail of ongoing evolution.
Whether you need a brand new product, a rewrite of a legacy system, or a specialised integration to connect your tools, we bring the technical depth and product thinking to make it ship.
Areas of focus
- ·AI-integrated products and internal tools — agents, RAG, eval pipelines.
- ·Web applications and bespoke SaaS for teams that have outgrown off-the-shelf.
- ·Legacy modernisation and platform migrations, without the all-or-nothing rewrite.
- ·Atlassian Forge plugins — a specialism we've invested heavily in (see the deep dive).
- Agile sprints
- CI/CD pipelines
- Full test coverage
Track record
Services delivered & in progress
A snapshot of what our custom development service has put into production, plus what is currently being built. We keep this list honest — own products are listed when they are live, client work is referenced anonymously where it has not been disclosed publicly.

How We Work
Audit before scope
Before we agree to anything, we look at what you already have — code, infrastructure, the bit that worries you the most. Half the time we find the problem is smaller than you thought. The other half it is bigger. Either way, you get an honest read before either of us commits.
Tackle the riskiest piece first
The thing most likely to derail the project gets built first, not last. If it does derail, we find out in week two, not month four. If it does not, the rest of the build is downhill from there.
Demo every Friday
Working code, not slides. You see what shipped, what is half-built, and what we are worried about, every week. No status reports, no monthly check-ins, no surprises at delivery.
Hand-off from day one
Code in your repo, deploy keys in your custody, hand-off docs written as we go. By the time the engagement ends there is nothing locked behind us. A retainer is optional, not a hostage situation.
