Professional web design and development consist of creating custom sites and applications with modern, scalable architectures, designed from the start for technical performance, user experience, and search engine positioning. At Centria Group, we develop using technologies like NextJS, NestJS, Python, and Django, deployed on cloud infrastructure (AWS).

Frequently Asked Questions (FAQ)
It depends on the scope, and the range is broad. A corporate site with a defined structure usually falls between 4 and 8 weeks; an e-commerce site with payment, inventory, and logistics integrations takes between 8 and 16 weeks; a custom web application can take several months. The factors that extend the timeline the most are the number of distinct templates, integrations with existing systems, and the time it takes the client to deliver content and provide validation.
Centria Group works primarily with custom development using NextJS, NestJS, Python, and Django, deployed on cloud infrastructure (AWS). This path offers more control over performance, security, and scalability than a generic solution. That being said, the technology is chosen based on the project: for a content site managed by a non-technical team, a well-configured CMS might be the right decision, and recommending it as such is more honest than selling unnecessary complexity.
By asking three questions. Is the website primarily content, or is there business logic (calculations, bookings, user accounts, integrations)? Does the traffic or data volume demand performance that a template cannot sustain? Is there a proprietary process that no off-the-shelf tool resolves? If the answer to all three is no, a well-implemented CMS is enough and costs significantly less. If any answer is yes, custom development usually proves cheaper in the medium term.
Yes, and that is the main difference compared to a purely aesthetic development. Loading speed and Core Web Vitals, semantic heading structure, structured data, clean URLs, accessible rendering for crawlers, and entity markup are incorporated from the very first commit. Fixing these things after launch costs several times more than doing them right during development.
The client. The domain is registered in the company’s name, the code is delivered in a repository that the client has access to and controls, and the cloud infrastructure is deployed in their own account whenever the client prefers. It is advisable to verify this with any provider: being tied to an agency because you lack access to the domain or code is one of the most common and costly situations to reverse.
Development and maintenance are distinct services and should be contracted as such. After launch, a site requires security updates, backups, uptime monitoring, bug fixes, and functional evolution. Centria Group offers maintenance plans with defined scopes and response times. A site without maintenance accumulates vulnerabilities and technical debt from the very first month.
Yes, if the migration is planned. Redesigns destroy rankings when URLs change without redirects, traffic-driving content is lost, or structured data disappears. The correct procedure includes a prior inventory of URLs and their performance, a 1-to-1 map of 301 redirects, preserving the content that works, and intensive monitoring during the first weeks post-launch. This is a phase that must be budgeted from the start, not improvised.
Yes. Centria Group implements conversational assistants using RAG (Retrieval-Augmented Generation) that answer based on the company’s actual documentation, agents that automate internal processes, semantic search engines, and functionalities based on models like GPT, Claude, or Llama. The choice of model and architecture is determined by the use case, expected volume, and data privacy requirements.
Yes, both custom e-commerce builds and implementations on established platforms. The decision depends on the catalog, transaction volume, and necessary integrations with local payment gateways, billing, inventory, and logistics. For standard catalogs, a consolidated platform shortens timelines and reduces costs; for unique sales models—configurators, per-client pricing, complex subscriptions—custom development avoids forcing a tool to do what it wasn’t built for.
Yes. Developments include an administration panel where the team can publish and modify content, images, and pages without touching code, along with a training session upon delivering the project. This is a requirement that should always be demanded: relying on the provider to change text makes daily operations more expensive and slows down any campaign.
Companies that need a custom site or application—not a template—and want the development to align with their positioning and digital growth goals right from the design phase.
