Backend development

Server-side systems and services in .NET and Node.js, built to handle growth.

What this service covers

We design and build the server side of products: business logic, data models, background jobs, queues and the services that tie them together. Most of our backend work is in .NET and Node.js, running on PostgreSQL or SQL Server.

We default to a well-structured monolith and split out services only when there is a clear reason, such as a component with very different scaling needs. That keeps early products cheap to run and easy to change.

Every backend we ship has structured logging, tracing, health checks and a load test result, so you know how far it will go before it needs more work.

What you get out of it

The results clients typically see. We agree the measures that matter to you during discovery.

  • 01

    A backend that handles 10× today’s load

    Load-tested against a target you set, with the results and bottlenecks written down.

  • 02

    p95 API responses under 200 ms

    Query tuning, caching and background processing keep user-facing requests fast.

  • 03

    Problems found in minutes, not days

    Tracing and structured logs mean a failing request can be followed across every service it touched.
