# Custom web application development

> Web apps for the day-to-day of your business, ready to grow. If you also need a mobile app, it shares the backend and data with the web so everything stays in sync.

## What's included

- SaaS platforms, ERP, CRM and internal portals.
- Multi-company and real-time with WebSockets.
- Laravel and MySQL on the server, Vue in the browser.
- APIs for mobile apps and external services.
- Deployment with Docker and CI/CD, with tests on every change.

## Already in production

Web apps of ours in production:

- Zurvyn, a modular SaaS platform with web and mobile apps on a single backend.
- Day-to-day portal for a network of advisory firms.
- ERP for a training center.
- CRM for an electricity and gas broker.

## How we work

- A clear estimate before we start, no surprises.
- Phased deliveries: you see progress early and always know where the project stands.
- Our own code, documented and reviewed: any team can pick it up.
- Deployment, monitoring and support once it's live.

## Common questions

### Do you build the mobile app too?

Yes. We build iOS and Android apps with React Native that share the backend and data with the web.

### Can several companies use the app at once?

Yes. We build multi-company, real-time platforms with WebSockets, like Zurvyn or our CRMs.

### How is it deployed and maintained?

With Docker and CI/CD: tests on every change, continuous deployment, monitoring and support.
