Back-End & API Development

.NET and Node services with database design, real authentication, and documented endpoints other systems can actually consume.

The problem

The back end is where the expensive mistakes hide. A schema designed around today's assumptions becomes the thing every future feature has to work around, and nobody notices until the third change request takes four times longer than the first.

APIs have a parallel problem. An endpoint built for one consumer, undocumented, with authentication bolted on late, becomes something nobody wants to touch — so a second endpoint gets built next to it.

What's included

  • .NET and C# service and API development
  • Node.js and Express services
  • Relational database design, indexing, and query optimization
  • REST and GraphQL API design with OpenAPI documentation
  • Authentication and authorization, including Entra ID and OAuth
  • Background jobs, scheduling, and message queues
  • Automated testing and CI/CD pipelines
  • Logging, monitoring, and alerting so failures surface before users report them

How we deliver

Discover, prototype, build, support

  1. Discover

    A paid, fixed-fee engagement producing requirements and a real estimate. You own the output.

  2. Prototype

    Clickable screens before code. Changing a wireframe takes an hour; changing a built screen takes days.

  3. Build

    Short increments with something demonstrable at the end of each. No six-month silence.

  4. Support

    Source code, documentation, and infrastructure handed over. Ongoing support optional, never required.

Back End & APIs: common questions

.NET or Node.js?

For line-of-business systems with heavy data and reporting, and in Microsoft-centric organizations, .NET is usually our recommendation. For lighter services, real-time features, and teams that already write JavaScript, Node is a better fit. We build in both and will tell you which suits the workload rather than defaulting to a favorite.

Can you build an API against our existing database?

Yes, and it's a common way to start. Exposing a documented, secured API over an existing system often unlocks integrations without touching the original application at all.

How do you handle security?

Authentication and authorization are designed in at the start, not added before launch. That means parameterized queries, secrets kept out of source control, least-privilege database accounts, and dependency scanning in the pipeline.

Have a project in mind?

Tell us what the process looks like today and where it breaks. Discovery turns that into a scoped, priced plan — and sometimes into advice not to build at all.
