Ingénierie logicielle d’entreprise

Développement d’applications web full-stack

Des applications web rapides et accessibles, conçues de bout en bout — des composants d’interface typés aux API, bases de données et infrastructures de diffusion — par une seule équipe responsable.

Vue d’ensemble

A web application is judged in milliseconds and maintained for years. Users notice slow pages, broken states and inaccessible forms. Engineering teams notice tangled front-end code, untyped APIs and deployments that take a weekend. Both problems usually trace back to how the stack was assembled.

We build full-stack applications with one type system running from database to browser where it makes sense, server rendering where performance and search visibility matter, and APIs designed as products in their own right. The result is software that loads quickly, behaves predictably and stays pleasant to change.

Applications métier

  1. 01

    Customer-facing web products

    Account portals, self-service applications and transactional products in which page speed, accessibility and reliability directly affect conversion rates, support volume and how much customers are willing to trust the business.

  2. 02

    Data-heavy operational interfaces

    Dashboards, back-office consoles and configuration tools that handle large tables, real-time updates and complex multi-step forms without sacrificing responsiveness, keyboard accessibility or the clarity that daily power users need.

  3. 03

    Content and commerce experiences

    Server-rendered and statically generated sites connected to headless CMS and commerce APIs, combining editorial flexibility with fast page loads and strong search engine visibility for product, campaign and support content.

  4. 04

    Front-end replatforming

    Incremental migration from AngularJS, jQuery or server-templated pages to a modern React stack, moving route by route so the business does not have to freeze feature work during the transition.

Approche d’ingénierie

  1. 01

    Experience and API design

    We define user journeys, information architecture and API contracts together, so front-end and back-end work can proceed in parallel against an agreed, typed interface.

  2. 02

    Rendering strategy

    For each route we choose static generation, server rendering, streaming or client rendering based on data freshness, personalization and performance budgets, rather than applying one pattern everywhere.

  3. 03

    Component and service build

    Interfaces are assembled from an accessible component library, and services enforce validation, authorization and error handling at the boundary, with shared types catching contract drift at compile time.

  4. 04

    Performance and accessibility checks

    Core Web Vitals budgets, Lighthouse runs and automated axe audits execute in CI, backed by manual testing with screen readers and keyboard-only navigation on critical flows.

  5. 05

    Release and observe

    Every pull request gets a preview deployment, production changes roll out progressively, and real-user monitoring with OpenTelemetry tracing surfaces regressions before customers report them.

Les questions des dirigeants

Why do you favor TypeScript across the stack?

Shared types between browser and server turn many integration bugs into compile-time errors and make refactoring safer as the codebase grows. It is a default, not a rule. When existing services are written in Java, .NET or Python, we generate typed clients from OpenAPI or GraphQL schemas to keep the same guarantees at the boundary.

Can you work within our existing design system and back-end services?

Yes. Many engagements start with an established design system, identity provider and set of APIs. We adopt your conventions, contribute components back where gaps exist, and add a backend-for-frontend layer only when it simplifies the client or shields it from unstable upstream contracts.

How do you approach accessibility?

We target WCAG 2.2 AA as the baseline. Accessibility is built into the component library, checked automatically on every pull request and verified manually with assistive technologies on key journeys. Automated tools only catch part of the problem, so manual review remains part of the definition of done.
