made to measure

Software, cut to exact dimensions.

Klijn is a small software studio. We design and build the systems businesses run on — customer-facing apps, internal tools, and the unglamorous plumbing that quietly holds everything together.

Scope of work

What we build, and what we don't.

We take a narrow set of things seriously rather than claiming to do everything. Each line below is a thing we've shipped more than once.

A.01
Web applications
Customer-facing products built to handle real traffic, real edge cases, and the years after launch.
A.02
Internal tools
Dashboards, admin panels, and workflows your team reaches for instead of working around.
A.03
APIs & integrations
Connecting the systems you already run so they stop fighting each other and start sharing data.
A.04
Technical advisory
A second pair of eyes on architecture, hiring, and the calls that are expensive to get wrong.
Method

Three phases. No surprises in between.

A drawing before a cut. Working software every week. A clean hand-off at the end.

PHASE01

Scope

We map the real problem before writing a line of code, and agree on what done looks like.

PHASE02

Build

Short cycles with working software you can use each week — so nothing is a surprise at the end.

PHASE03

Hand off

Documented, tested, and entirely yours. No lock-in, no retainer you can't leave.

Plain language

No jargon standing between you and a decision. If we can't explain it simply, we don't understand it yet.

Fixed scope, honest estimates

We'd rather say no to a date than miss one. The number we quote is the number we mean.

Maintainable by design

Code another developer can read in a year — including the one who replaces us.

A short note about the problem is enough to start. We'll reply with whether we're the right studio for it — and if we're not, who might be.
