Client: Bluberry (Startup – Cleaning Staff & Client Scheduling Platform) Duration: 3 months (Freelance) Stack: React, Axios, Zustand, Material UI, REST API, QuickBooks

Overview: Bluberry is a web platform designed to connect cleaning staff with clients, enabling easy management of bookings, roles, cleaning inventory, and scheduling. The application supports onboarding flows for both clients and staff, with dashboard views and business integrations such as QuickBooks for billing.

My Role: As a freelance frontend developer, I contributed to the stabilization and UX improvement of the app by:

Fixing over 15 critical bugs affecting core functionality

Fully redesigning the onboarding experience for both cleaning staff and clients, based on Figma designs

Redesigning and implementing the main dashboard UI, improving layout and updating existing charts for better data clarity

Refactoring large parts of the legacy codebase to align with modern frontend standards — breaking down large, tightly coupled files into smaller, reusable components

Collaborated closely with the product manager and design team to ensure feature alignment

Challenges & Solutions: The most complex task was integrating the new onboarding flow into an aging and difficult-to-maintain codebase. To overcome this, I carefully refactored the relevant files, modularized the code, and separated logic from components — resulting in a cleaner structure that made future development easier.

Improved code maintainability and onboarding flow UX

Enhanced dashboard design and data visualization clarity

Fixed critical bugs that improved app stability and client satisfaction

Received positive feedback from both the client and product manager for speed, reliability, and code quality
