02Process

Four steps to your app

  1. 1. Discovery and plan

    We talk about goals, users and constraints. The result is a specification with priorities, an estimate and a delivery plan.

    • Specification
    • Estimate

  2. 2. Design and prototype

    We test the interface and user flows on a clickable prototype before the first line of code.

    • UX flows
    • Design system
    • Prototype

  3. 3. Iterative development

    We ship in short cycles, with automated tests and continuous integration. You see progress regularly, not just at the end.

    • Iterations
    • Tests
    • CI/CD

  4. 4. Launch and growth

    Store release, error and performance monitoring, new versions. Launch is the beginning, not the end.

    • Release
    • Monitoring
    • Maintenance

05Questions

Questions

Which technology do you use for the web?

We choose by purpose: Next.js or Astro for sites and portals where SEO matters, Flutter Web for complex business interfaces that share code with a mobile app, and FastAPI with PostgreSQL for the backend.

Will the site be visible on Google?

We build SEO in from day one: server-side rendering, fast loading, structured data, a sitemap, canonical URLs and hreflang for multilingual sites. Rankings also depend on content and competition, but the technical foundation will be solid.

Can a web app work on phones too?

Yes. Responsive web apps work on any screen and can be installed on the home screen as a PWA — which is exactly how MovIQ works.

Where will the app be hosted?

Usually in Docker containers on DigitalOcean, with automated deployments. If you have your own infrastructure, we will adapt to it.
