Web development: features built around how you work

You have mockups to integrate, a client portal to build or a form to connect to your CRM. Our web development agency turns these needs into features your clients and teams can use. We work on new websites as well as existing platforms, after checking how they run and what constraints they carry.

Document library, search engine, simulator or approval workflow: we define with you the users, data and rules to handle. For a document library, for example, we define who can view, add or replace a document, then test these permissions with your teams before going live.

Front-end development brings screens and interactions to life; back-end development handles data, permissions and exchanges with your software. We take on both, depending on your needs. If the user journeys and design still need to be created, our website design and development service covers that preparation too.

Integration and technical choices

Figma integration, WordPress, Drupal and custom development

We review your Figma mockups and the intended behavior: mobile display, navigation, forms, animations and error states. Any gaps are clarified with the designers before integration. Your screens become reusable components, true to the approved design, so the interface stays consistent as you add content.

WordPress or Drupal development covers page templates, editable content and publishing permissions. We evaluate existing plugins before building a custom feature, to avoid unnecessary dependencies. A custom architecture may be chosen when usage or data exchanges justify it, with its maintenance planned from the start.

We also build API connections, which let the website communicate with your software: CRM, sales management, directory or booking tool. With your technical teams, we define the data exchanged, the permissions and how errors are handled. For a form connected to the CRM, we test contact creation, duplicates and recovery from an interrupted submission, so your team can spot a request that did not go through.

Reliability and technical follow-up

A web development agency that plans for what comes next

Behavior approved with you

You can review a staging version as development progresses. Demos are used to check screens, features and business rules against scenarios agreed together. Your feedback is collected in a list of fixes; new needs are separated from bugs before deciding next steps.

Code takeover

We review access, dependencies and documentation before taking over existing development. This first analysis helps distinguish targeted fixes from a larger rebuild.

Technical quality

Checks focus on real-world use: invalid input, access rights, connection errors and mobile display. We also check performance and the markup that matters to Google.

Maintenance and updates

We prepare documentation, access and deployment instructions to make the project easy to pick up. Updates and bug fixes fall under website maintenance; new features are quoted based on their scope.

Your questions about custom web development

  • Yes. We review your Figma files, mobile versions and expected interactions. We flag the screens or behaviors that need clarifying, then define the integration scope. Technical adjustments are approved with your designers before development.
