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.

Hello — For an existing React 19/TanStack Start appointment SaaS, I would implement the approved UI in place, not rebuild routes or business logic. The risk is regressions across scheduling, payments, permissions, and the public booking flow, so I would change components behind the current TanStack Query/Supabase contracts. - Figma specs mapped to pixel-accurate Tailwind components and shared patterns. - Existing forms, tables, modals, nav, and responsive states updated consistently. - TanStack Router/Query behavior preserved; API and auth flows stay intact. - Desktop/mobile QA in current browsers with fixes committed to GitHub. I can start by auditing the component structure, then implement screen groups in reviewable PRs. Are the approved screens already in Figma? Roman

This is less about “building screens” and more about updating a live booking SaaS without breaking scheduling, permissions, payments, or onboarding flows. For this kind of job, the first step is usually mapping the approved designs against the existing component structure so the UI can be upgraded cleanly while preserving current logic and avoiding regressions. I’ve handled frontend work in existing React/TypeScript products where the real challenge was consistency across dashboards, forms, tables, modals, and mobile states inside a mature codebase. Working with Tailwind in SaaS interfaces, I focus on reusing and tightening existing components instead of doing disruptive rebuilds that create QA problems later. A small bonus from my side is cleaner component consolidation where it helps maintainability. - Are the approved designs in Figma with responsive states and interaction notes? - Roughly how many core screens/modules are included in this implementation phase? - Do you already have a shared component system in the app, or is part of the work standardizing that as we implement?

Hi, I will take your approved UX designs and build them directly into your existing React 19 and TypeScript codebase using Vite and Tailwind CSS. I will review your TanStack setup and Supabase data flows first so I can map out every screen from the business dashboard and team management to the public booking pages without touching your core business logic or permissions. I will work directly in your GitHub repository by updating shared components and refactoring forms, tables, modals, and navigation to match your new specifications pixel by pixel. I will check responsive behavior on both desktop and mobile views so layouts stay clean across all screen sizes while preserving your existing database behavior and authentication. One smart thing I will do as I go is clean up unused CSS classes in your Tailwind setup to keep load times fast for your users. How are you currently handling design handoffs, through Figma links or redlines? Best, Salma Noreen

The key risk here is not “making screens look better” — it’s applying the approved redesign across a live booking SaaS without disturbing auth, permissions, scheduling flows, payments, or existing business logic. I’d approach this by mapping the affected modules first, reusing/refactoring current components where possible, and implementing screen-by-screen with regression awareness rather than doing broad visual rewrites. I’ve worked on React/TypeScript dashboard products where the hard part was keeping established behavior stable while modernizing tables, forms, navigation, modals, and responsive layouts. Tailwind-based UI cleanup inside an existing codebase is very different from building fresh pages, and that distinction matters here. A small plus from my side: I can help keep the UI implementation consistent across shared components so QA feedback stays manageable. - Roughly how many screens/views are included in the approved redesign? - Are the designs already in Figma with full states/responsive specs, or partly documented elsewhere? - Do you want this handled module by module in milestones, or as one full implementation pass?

I’d start by mapping the approved UX specifications onto the existing React 19/TanStack routes and shared Tailwind components, especially the dashboard, scheduling, tables, forms, modals, and responsive navigation. The implementation will reuse and refine the current UI rather than replace working business logic, preserving Supabase data behavior, permissions, authentication, payments, and public booking flows. Within 7 days, I’ll deliver the approved UX/UI implementation across the supplied SaaS areas, committed to your existing GitHub repository and adjusted for desktop and mobile feedback. I’ve built ClearAgent, a multi-tenant customs-clearing SaaS used by a live agency operation, so I understand the care needed when improving a business platform without disrupting its workflows. Are the approved designs provided in Figma, or as screenshots and written specifications? Muhammad Saad

When a project involves implementing UX/UI changes while maintaining existing functionality, the core challenge lies in making sure consistancy and stability throughout the codebase. I understand the importance of preserving your current application while enhancing its user experiance. My approach will be as follows: Safe staging build: full site built on a private staging area first, live site untouched. Design implementation: apply approved designs and specifications across all components. Thorough testing: make sure no regressions or functionality loss through rigorous QA. Final deployment: push changes to the live site with minimal disruption. I will work carefully within your existing codebase, committing to GitHub as needed. My rate for this project is 169 USD. Please let me know if there are any specific components or areas you want me to prioritize during implementation. Rajavel

Hi, I’m very interested in this project. I have worked on an appointment-based platform with scheduling, user roles, payments, dashboards, and administrative workflows, so I understand how closely the interface is tied to existing business behavior. I can implement your approved designs accurately within the current React 19 and TypeScript codebase without turning the work into an unnecessary rebuild. My workflow would be: - Audit existing routes, components, states, and responsive behavior - Map every approved screen to reusable UI components - Establish consistent Tailwind tokens for spacing, typography, colors, and states - Implement changes in small, reviewable sections - Preserve TanStack Query caching, form behavior, permissions, and integrations - Test scheduling, payments, authentication, booking, and admin workflows after UI changes - Compare implementation against supplied designs across desktop and mobile - Submit focused GitHub commits and resolve QA differences promptly I pay particular attention to loading, empty, validation, error, disabled, and permission-dependent states—the areas often missing from static mockups but essential in a production SaaS product. I’m comfortable navigating large existing repositories and improving component consistency while preserving public APIs and working logic. I’m ready to review the design files, codebase structure, priority screens, and acceptance process. Best

Since the UX decisions are already made, this comes down to precise frontend execution in an existing app without disturbing the product underneath. The key is translating the approved layouts, spacing, forms, tables, and responsive states into the current React/Tailwind structure while keeping routing, auth, and data behavior stable. I’ve worked on implementation-focused UI updates for established web apps where accuracy to design mattered more than adding personal design input. That usually means reviewing existing reusable components first, applying changes module by module, and testing carefully so the dashboard and public-facing booking pages stay consistent across desktop and mobile. If helpful, I can also keep changes organized in a way that makes QA comparison easier. - How complete are the handoff files: final screens only, or also component specs/states? - Are public booking pages included in the same phase as the internal dashboard/admin updates? - Is there an existing staging environment for review before anything is merged live?
