Sydney .NET development company

We are a Sydney-based .NET development company focused on building products with the .NET ecosystem for Australian web, SaaS, and AI products. Our senior engineers work directly inside your repo, your CI, and your hosting, so .NET 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.

.NET consultants for production-grade builds

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

We focus on architecture reviews, performance work, and senior delivery on .NET, so the parts of your stack nobody trusts to change stop being a bottleneck for the rest of the product.

What we build with .NET

We build .NET with the strengths it actually has: strong typing, fast runtime, and tooling that pays off when you respect it.

ASP.NET Core APIs

REST or minimal APIs with consistent validation, auth, and versioning so clients can evolve independently.

Service backends and workers

Background services, schedulers, and message handlers built around real operational concerns.

Integrations

Connect third parties (Stripe, ServiceNow, ERPs) with retries, idempotency, and observability baked in.

Data access patterns

EF Core or Dapper used deliberately, with migrations teams can review.

Modernisation and .NET upgrades

Move from .NET Framework or older .NET Core versions to current LTS in safe slices.

Performance and observability

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

Why .NET teams work with us

The build starts with how your .NET services actually run in production, not a sample app from a Microsoft tutorial.

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.
