Backend & APIs

Backend and API development that scales with you

We build the secure, scalable systems behind your apps — APIs, databases, authentication, and real-time services — so your web, mobile, and admin products all run on one reliable foundation.

Your app is only as good as its backend

Slow APIs, inconsistent data, and security gaps don't show up in a demo — they show up when real users arrive.

We design backends with clear data models, proper authentication, and room to grow, so adding a new app or feature doesn't mean starting over.

Backend & API Development: frequently asked questions

Which backend technologies do you use?

Mainly .NET / C# and Node.js, with PostgreSQL as our default database, plus MongoDB, Redis, and Firebase where they fit. We choose based on your requirements and team.

Can you build an API for our existing app?

Yes. We can build new APIs, extend existing ones, or migrate a legacy backend gradually without downtime.

How do you handle security?

Role-based access, encrypted data in transit, secure authentication, input validation, rate limiting, and security testing before release.

How is pricing structured?

We work on a fixed-price milestone model. After a free 30-minute discovery call, we send a Scope of Work within 24–48 hours with the architecture, milestones, timeline, and a fixed cost. No hourly billing and no surprise fees.

What happens after launch?

Every project includes a free 30-day post-launch warranty covering bug fixes. After that, optional monthly maintenance plans cover feature updates, server monitoring, security patches, and performance tuning.
