Sydney Kotlin development company

We are a Sydney-based Kotlin development company focused on shipping production Kotlin code for Australian web, SaaS, and AI products. Our senior engineers work directly inside your repo, your CI, and your hosting, so Kotlin is treated as part of the product, not a separate experiment.

From greenfield builds to inherited codebases that have started fighting back, we ship in short, reviewable increments with clean architecture, real tests, and integrations that match the systems you already run.

Kotlin consultants for teams that need to ship

Need a second opinion, a focused sprint, or ongoing senior help on Kotlin? Our Kotlin consultants come in at the depth you need, from a one-week review to embedded delivery alongside your team.

We focus on code reviews, refactors, and senior delivery in Kotlin, so the parts of your stack nobody trusts to change stop being a bottleneck for the rest of the product.

Kotlin development solutions we provide

We build Kotlin with the structure it deserves: typed contracts, clear modules, and operations that hold up.

JVM services and APIs

Spring Boot or Ktor services with consistent validation, auth, and versioning.

Native Android apps

Kotlin and Jetpack Compose apps with predictable architecture and a release process that holds up.

Migrations from Java

Move Java codebases to Kotlin in safe slices, without halting feature work.

Performance and observability

Profile real production paths, fix what matters, and wire metrics that point at problems.

Why teams choose Webhouse for Kotlin

The build starts with how your Kotlin actually runs today, not the sample app from a conference.

1

Built Around Real Workflows

We do not force generic patterns onto your product. Your users, constraints, and release cadence set the brief.

2

Integration-First Thinking

Your stack already exists. We extend and connect it instead of asking you to rip everything out and start over.

3

Designed for Shipping Teams

We build for teams that need changes to land safely, quickly, and with clear review paths, not mystery deploys.

4

Practical Delivery

We focus on maintainability, performance, and outcomes instead of demo features nobody adopts.

5

Long-Term Support

Products evolve. We build for iteration, new requirements, and ongoing improvement instead of one-off launches.

6

Clear Communication

You get plain-English scope, direct delivery, and straightforward next steps without disappearing into a dev cave.

Proof, not pitch decks

Named Australian projects with public write-ups, so you can see how we work before the first call.
