The technologies we use to build your site or app
We pick the tool that fits what your business needs. These are the ones we work with and how they apply to a real project.
Front-end development
The front end is everything people see and touch on your site. We code it with standard HTML, CSS and JavaScript, with responsive design that looks right on phones, tablets and computers.
- Clean, semantic code that search engines understand better.
- Fast loading: optimized images and no unnecessary libraries.
- Basic accessibility: contrast, image alt text and keyboard navigation.
- No template that limits the design.
WordPress and WooCommerce
When the client wants to edit content or needs a store, we use WordPress and WooCommerce. We prepare the theme, pages and configuration and deliver them ready to install on your hosting.
Mobile apps
We build Android apps with React Native and Expo. It is the technology behind our own app, Centify, published on Google Play.
Database, users and panels
For client portals, management panels and apps we use Firebase: user authentication (email or Google sign-in), the real-time Firestore database and security rules that define who can see or change each piece of data.
Web security
- HTTPS with an SSL certificate: the browser padlock. We enable it on the hosting and force the whole site to load over HTTPS.
- Protected forms against automated messages (spam) with captcha.
- Access rules in the database so each user sees only their own data.
- Backups and updates, included in the monthly maintenance plans.
Technical SEO and measurement
Technical SEO is the part of Google ranking that depends on how the site is built. This is what we apply:
- Every page with its own address, title and description.
- Canonical tags and, for two-language sites, hreflang tags.
- Structured data (schema.org) so Google understands what your business is.
- Sitemap (sitemap.xml) and robots.txt.
- Loading speed and mobile design, which Google takes into account.
- Google Analytics 4 with a cookie notice, and Search Console to measure.
What technical SEO does promise is that your site can be found and understood. We cannot guarantee a Google position: it also depends on content, competition and time. Anyone who guarantees first place is not telling you the truth.

Frequently asked questions
Do you use Kotlin or Swift?
Our apps are built with React Native, which lets us build an Android app with JavaScript. If your project requires native code, we tell you before quoting.
Can you connect to my WordPress?
We prepare all files and configuration and deliver them with installation instructions. We do not access your site unless you expressly give us access.
Does the site include an SSL certificate?
Yes. We enable HTTPS on the client's hosting; most providers offer it at no extra cost.
