expertise

Adaptive UI development via standard apis and/or frameworks, starting from mock-ups provided by the designer, or from existing ones.

Digital accessibility compliance (RGAA) for consumer-facing sales applications.

Code reviews and setup of tools to standardize the code base (linters), and thus ensure its quality is maintained.

Components library creation (« design system »), designed and tested in isolation with Storybook, then published as versioned packages (private npm registry) and documented through interactive examples.

Code base restructuring ("refactoring") iteratively during evolutions and bug fixes, thereby resolving technical debt as it happens, without significantly disrupting the product managers' roadmap.

Automated tests for quality deliverables: unit testing, integration testing - "end-to-end" and continuous integration (CI/CD).

Documentation writing (project installation instructions, development guide) increasing code maintainability.

Assistance in products design by supporting product managers in their functional choices and conducting feasibility studies (proofs of concept) where appropriate.

Applications implementation from scratch: choosing of "build" tools, frameworks, project structure, breakdown into modules.

Data access via apis - REST, GraphQL, websockets - provided by the "back-end" teams.

Mock-ups and promotional visuals.

typical applications

Web application for managing digitized contracts, allowing drafting, importing and electronic signature, passing through validation processes involving several actors.

Online money games and tools to help develop said games, for example, a web IDE.

Mobile apps: low cost train ticket booking parcel post tracking luggage concierge.

E-commerce web sites: individual to individual retailer train ticket booking clothing.

Promotional sites.

Sequences of short promotional animations.
