Work implementedUser Interface Upgrade, WCAG 2.1 standards implemented, Rapid development
The client — a leading employee recruitment company — was looking to improve the user experience of its web-based questionnaire tool.
Challenges
Toughlex joined a team with a highly dynamic structure and working style, while the project's requirements and deadlines remained fixed.
  • A continuously shifting remote team created challenges around clear communication, ownership of responsibilities, and overall efficiency.
  • The application needed to support a very wide range of devices, including older ones.
Goals
The primary goal was to deliver a redesigned user interface quickly — fully compliant with an extensive set of accessibility and device compatibility requirements. To make this achievable, we applied a strict code quality standard and high unit test coverage to ensure the project remained maintainable and well documented.
  • Deliver a complete tool redesign
  • Meet accessibility requirements in line with WCAG 2.1 standards
  • Support all devices with more than 0.2% usage according to caniuse.com data
Created Value
The client assembled a new team for the project, which required Toughlex to adapt quickly and propose improvements to team communication and the division of responsibilities. Working in a fully remote environment, clear and responsive communication across the whole team was essential throughout development.
AgileThe project was delivered through regular communication with the client and frequent demonstrations of completed features. This minimized the risk of misalignment between business and development, and allowed the team to find the right balance between value delivered and development time at each stage.
Rapid DevelopmentFrom the start, it was agreed that a demo version compliant with all relevant code standards and test coverage requirements would be delivered within a few sprints. Through quick communication cycles and modular partitioning of the application into self-contained components, the team worked in parallel without blocking each other, making effective use of available development time.
OutcomeToughlex became a productive part of a dynamic team that delivered a web application compatible with nearly all device types, along with multiple design variants suitable for use as white-label products — including accessibility-adapted viewing modes for users with disabilities. The application integrated seamlessly as a standalone component into the client's existing project. The resulting MVP met all technical requirements and was received very positively by the client.
Technologies
Toughlex joined the project for its React expertise. The project was initialized using Create React App for quick prototyping. TypeScript was used as the language of choice — bringing additional readability and maintainability to the codebase. Unit testing was handled with the Jest framework, extended with the React Testing Library. Backend API communication was implemented using GraphQL.
