Overview

The engine behind your product.

Your users see the UI. Your engineers live in the backend. We build server systems that are reliable, secure, and easy to change — because a good backend is one you can keep shipping against a year from now.

It’s the right fit for teams building a new product, replacing a monolith that’s slowing them down, or scaling an API that’s starting to buckle.

FAQ

Common questions.

Monolith or microservices?

Start with a well-structured monolith unless you have real reasons to split. We’ll be honest about which fits.

How do you handle security?

Auth, RBAC, input validation, secret rotation, audit logs, and a threat model reviewed at every phase.

Can you scale an existing backend?

Yes — load testing, caching, database tuning, and horizontal scaling.

Do you plug into our existing frontend?

Yes — we deliver an OpenAPI/GraphQL contract and integrate.

What does it cost?

Fixed price after discovery. Most first APIs land in a defined range.
