Work with senior .NET engineers.

.NET engineers who ship production systems, not pitch decks.

We build production .NET systems for US product teams every week. Senior engineers, aligned with your timezone, embedded in your process. We write .NET the way your team will still want to read it next year.

Why Sonnet Code for .NET

The bar we hold ourselves to.

Senior only

Every engineer we put on your work has 5+ years shipping production code. No rotations out, no bait-and-switch.

Measured, not promised

Performance budgets, observability, and evaluation metrics are part of the build — not things we add after you ask.

Honest scoping

We'll tell you when this is the wrong tool for the job. The fastest way to lose a client is to ship the wrong thing.

What we build with .NET

.NET work, shipped.

New .NET systems

Greenfield .NET services architected for the three-year horizon — proper boundaries, tests, and documentation from day one.

.NET modernization

Incremental migration from legacy systems, using the strangler-fig pattern so you never bet the farm on a single cutover.

.NET scaling

Taking an existing .NET codebase from working-for-10k-users to working-for-10M-users, without a full rewrite.

.NET team augmentation

Senior .NET engineers embedded in your team, shipping alongside your engineers with the same standards and PR process.
