Custom Software Development

Custom software built in your stack, shipped on a plan

Web apps, APIs, integrations and SAP development in .NET, React, Java and Node — delivered as a fixed-scope project or a dedicated squad embedded in your team. Estimate and architecture first, build second.

Developer building a custom software application

Most custom builds overrun because the plan came after the code.

We do the unglamorous part first: a discovery that produces a real architecture, estimate and build plan, so you approve a number and a scope before development starts. Then we build in two-week increments — in your stack, your conventions, with tests alongside the code — so "done" means deployable, not demo-able.

What we build

From a single API to a dedicated delivery squad.

Web applications

Customer portals, internal tools and line-of-business apps built in React on the front and .NET, Java or Node on the back — typed, tested and deployable from day one.

APIs & integrations

REST and GraphQL APIs, third-party integrations and the glue between systems that never quite talk to each other — built to be observable, not a black box.

SAP development

SAP technical development and integration work alongside the functional side, so the custom build and the ERP actually meet in the middle.

Legacy modernisation

Incremental migration of aging .NET and Java systems off frameworks that are now a hiring and security liability — without a risky big-bang rewrite.

Dedicated dev squads

A cross-functional team embedded in your process and repo — your roadmap, our delivery — when you need throughput without permanent headcount.

Discovery & architecture

A fixed-scope discovery that produces an architecture, estimate and build plan before the meter starts running on the build itself.

How a build runs

Architecture and estimate up front, working software every two weeks.

01

Discovery & scope

We turn the brief into a concrete spec, architecture and estimate — so you approve a plan, not a blank cheque.

02

Architecture & setup

Data model, API contracts, CI pipeline and environments stood up first, so the build doesn't get re-plumbed halfway through.

03

Iterative build

Two-week increments with working software you can see, in your stack and conventions, with tests written alongside the code.

04

Ship & hand over

Production deployment, documentation and a clean handover — or an ongoing support arrangement if you'd rather we keep it running.

Frequently asked questions

What technologies do you build in?

Primarily .NET, Java and Node on the backend; React on the frontend; plus SAP technical development. We also build Shopify apps as a specialised track — see our Shopify app development service.

Do you do fixed-scope projects or staff augmentation?

Both. We can take a defined project end to end on a fixed scope, or embed a dedicated squad inside your team under your roadmap and process. The right model depends on how defined the work is.

How do you estimate a build?

We run a fixed-scope discovery that produces an architecture, a build plan and an estimate before committing to the build. You approve the plan and the number before development starts.

Can you modernise an existing legacy system?

Yes. We favour incremental modernisation — migrating a legacy .NET or Java system module by module behind a stable interface — over a big-bang rewrite, which is where most modernisation projects fail.

Who owns the code and IP?

You do. Code is delivered into your repositories, and IP ownership transfers to you under the engagement contract.

Do you handle deployment and hosting?

Yes — we set up CI/CD and cloud infrastructure as part of delivery. For dedicated platform and CI/CD work, see our DevOps engineering service.

Have something to build?

Tell us what you're trying to ship. We'll run a discovery and come back with an architecture, a plan and a number.
