Web development agency in Tarragona

Web development agency in Tarragona, from WordPress to custom apps

We develop from WordPress sites to complex web applications with Angular, React, or Vue. One agency for your entire digital stack.

One agency for your entire stack, not a puzzle of providers

Most businesses in Tarragona hire a designer, a WordPress developer, another for the app, an SEO consultant, a hosting, a maintenance. Five contacts, five invoices, zero global vision. A full-service web development agency gives you a single team that understands your project end to end.

Lo que ganamos contigo

  • Real full-stack

    Front, back, infra, SEO, maintenance. If you need it, we cover it. No we do not do that, find someone else.

  • Modern stack

    WordPress with custom theme, Angular/React/Vue for apps, Node and PHP in back, AWS/Cloudflare for infra. What fits, not just what we know.

  • Maintainable code

    No spaghetti code, no abandoned dependencies. What we deliver can be maintained for 5 years without breaking.

  • Coherence across products

    Your WordPress site and your custom app share brand, share data when needed, share maintenance. One agency, one vision.

  • Optimised cost

    €1,000 on a landing is not the same as €1,000 on a custom app. We tell you what you actually need and what is over-engineering.

  • No team rotation

    When you hire Sincronía, you hire Roberto. They do not change your account manager every 3 months.

  • Maintenance and evolution

  • Specialised hosting

    AWS Lightsail with stack of 15 premium plugins included. Or your own cloud if you prefer. We configure what you need.

Development process

  1. 01

    Technical discovery

    We define scope, requirements, stack, timelines. Without this phase, everything is a we will see that always goes wrong.

    UX/UI design

    Wireframes, mockups, interactive prototypes. We validate with you before touching code.

  3. 03

    Iterative development

    2-week sprints with demos. You see real progress, not PowerPoint slides.

  4. 04

    QA and testing

    Automated tests, manual testing, accessibility review, performance audit. Before launch, everything works.

  5. 05

    Launch and support

    Production migration, monitoring and ongoing support. We stay with you for whatever comes next.
