Custom web application development

When a tailor-made tool makes sense

Shared spreadsheets, off-the-shelf software configured to its limits and files sent back and forth by email eventually slow a team down. A web application designed for your business replaces these workarounds with a single tool, available in any browser, which your colleagues adopt because it uses their own words and their own steps.

Typical projects: a portal where your customers follow their requests, a scheduling tool for field interventions, an extranet reserved for your suppliers, an internal catalogue with role-based access, or the programming interface that feeds a mobile app. Small-business owners, heads of business teams and startup founders are the first to ask for them.

What a turnkey application includes

• workshops to describe roles, screens and business rules, recorded in a short document;
• clickable mock-ups, approved before a single line of production code is written;
• a responsive interface, usable with a keyboard and readable on a phone as well as a large screen;
• a database sized for your volumes, with encrypted backups and a tested restore procedure;
• authentication, fine-grained permissions and logging of sensitive actions;
• an automated test suite, operating documentation and source code that belongs to you.

What artificial intelligence changes for your application

AI drafts the first versions of repetitive code, suggests test cases and spots inconsistencies between the specification and what has been written. Every suggestion is reviewed: architecture, data model and security choices remain human decisions, made with full knowledge of the facts.

On the security side, AI-assisted analysis tools scan the code at every change, then the application faces realistic attack scenarios, run on your acceptance environment with your written authorisation — including penetration tests with written authorisation when the stakes justify them.

Milestones of an application project

Discovery workshop

Half a day to map the users, today’s pain points and the indicators that will show whether the application has done its job.

Clickable prototype

Key screens become navigable within days: your teams try them out and adjust course before costs build up.

Releases every two weeks

Each increment is demonstrated, tested and deployed to an acceptance environment you can explore at any time.

Acceptance with your users

Volunteer users validate the real journeys; feedback is sorted, estimated in effort and scheduled according to your priorities.

Opening to production

Migration of existing data, training for the first users and closer monitoring during the first weeks of use.

And once the application is live?

An application lives on: libraries publish fixes, your needs change, new uses appear. Maintenance and enhancements for your application take over in the long run, and a web security audit can be repeated before each major release.
