otnaco builds software


otnaco is a small Sydney-based company building a portfolio of software products. Alongside that work, we take on selected client engagements in custom automation and product development.

Our own work is in private development. We're open to a small number of client engagements through 2026.

Client work keeps the practice sharp. We take on a small number of engagements where the fit is right.

Custom automation
Removing the manual steps in how a business runs: workflows, back-office processes, the glue between systems.
Product development
Web applications and services designed, built and operated end to end, from first sketch to production.
Systems integration
Making the tools a business already runs talk to each other, reliably and without human glue.

Alongside client work, we're building a portfolio of our own software products. They're in private development now; the first will take its seat here when it ships.

Small by design
You talk to the people doing the work. Nothing is handed off or lost in translation.
Ship, then operate
We stay with what we build: deploys, monitoring, the unglamorous parts that keep software alive.
Plain answers
If something is harder than it looks, or not worth doing at all, we say so early.
Boring on purpose
Proven technology, tested and documented, chosen so the software outlives the engagement.
