SaaS UX/UI Implementation (React / TypeScript / Tailwind)

looking for an experienced Frontend Developer to implement an approved UX/UI redesign across an existing appointment-booking SaaS platform.

The UX review/design will already be completed. This is primarily an implementation role, not a UX strategy or redesign role. You will take the approved designs, recommendations, and specifications and accurately implement them in the existing application while preserving current functionality.

The platform includes a business dashboard, scheduling and appointments, clients, services, team management, reports, payments, settings, public booking pages, authentication/onboarding, and an internal staff/admin portal.

Responsibilities:

* Implement approved UX/UI changes throughout the existing SaaS application
* Match supplied designs/specifications accurately
* Improve layouts, spacing, typography, forms, tables, navigation, modals, responsive behavior, and other UI components as specified
* Ensure consistent implementation across desktop and mobile
* Reuse and improve existing components instead of unnecessarily rebuilding them
* Preserve existing application functionality, business logic, permissions, authentication, database behavior, and integrations
* Avoid introducing regressions while changing the interface
* Keep implementation clean and consistent with the existing codebase
* Commit all work to the existing GitHub repository
* Work through feedback and correct implementation differences found during QA

Current stack:

* React 19
* TypeScript
* TanStack Start / Router / Query
* Tailwind CSS
* Vite
* Supabase / PostgreSQL
* Cloudflare
* GitHub

Ideal candidate:

* Strong React + TypeScript frontend experience
* Experience implementing professional SaaS dashboards/products
* Strong Tailwind CSS and responsive design skills
* Able to implement an existing UX design rather than redesigning based on personal preference
* Comfortable working in a large existing codebase
* Careful about preserving existing functionality
* Experience with Supabase is helpful
* Experience with appointment, scheduling, CRM, or business-management SaaS is a plus

Important: This is an existing product with working functionality. We are not looking for someone to rebuild the application from scratch. The goal is to accurately implement the approved UX improvements while keeping the underlying product stable.
