Frontend Redesign for Better-Half.ai to Align with AI Experience
Context
Better-Half.ai’s core product is driven by conversational AI. However, the existing chat interface did not fully reflect the intelligence, responsiveness, and emotional clarity of the underlying AI system.
The challenge was to redesign and rebuild the frontend chat experience so that it:
Felt intuitive and familiar to users
Matched the quality and personality of the AI
Scaled reliably under real-time messaging conditions
Integrated seamlessly with existing and evolving backend systems
Could be embedded effortlessly across external platforms
Objective
To deliver a modern, high-performance chat interface that enhances AI interactions, improves user engagement, and supports long-term scalability—while ensuring full compatibility with all existing backend services and enabling new integrations where required.
Solution Overview
The project involved a full frontend overhaul combined with deep backend integration work, covering design, architecture, real-time messaging, authentication, and deployment.
In addition to the UI and client architecture, I was responsible for integrating all existing backend services and implementing new backend integrations needed to support the redesigned experience.
Key Contributions
1. UX/UI Redesign Inspired by Apple iMessage
Complete redesign of the chat interface inspired by Apple’s iMessage
Focus on:
Clear conversational flow
Visual hierarchy and readability
Modern, minimal aesthetics aligned with AI interactions
Designed to ensure the UI reinforced trust and clarity during AI-driven conversations
2. Design-to-Code Execution
Converted UI designs directly into production-ready frontend code
Delivered Figma design assets alongside implementation
Maintained exact design fidelity while ensuring performance and scalability
3. Backend Integrations (Existing & New)
Integrated all existing backend APIs and services into the redesigned frontend
Implemented new backend integrations required for:
Real-time chat flows
AI response handling
Message state synchronization
Ensured clean, well-structured API consumption with proper error handling and fallbacks
This guaranteed that the new UI worked seamlessly with the full backend ecosystem.
4. Real-Time Messaging Infrastructure
Integrated and configured WebSockets for real-time communication where applicable
Implemented efficient polling mechanisms for reliability and fallback scenarios
Ensured message delivery consistency under varying network conditions
5. Migration to Next.js Client-Side Application
Migrated the chat application to a Next.js client-side architecture
Improved:
Application structure
Maintainability
Scalability for future AI features
Enabled faster development cycles and cleaner separation of concerns
6. Performance & Responsiveness Improvements
Optimized message rendering and state updates
Improved responsiveness across desktop and mobile devices
Reduced perceived latency during AI interactions
7. Authentication & Session Management Enhancements
Integrated backend authentication systems into the new frontend
Improved session handling and persistence
Ensured secure, consistent user state across reconnects and page refreshes
8. Embeddable Chat Widget Packaging
Packaged the chat application as a standalone embeddable widget
Delivered via a single script tag for easy integration
Implemented strict isolation to prevent:
CSS conflicts
JavaScript namespace collisions
Interference with host applications
9. Delivery & Validation
Delivered:
Complete frontend source code
Fully integrated backend connections
A working demo environment
Final acceptance completed after confirming:
All backend integrations functioned correctly
UI/UX met design expectations
Performance and reliability standards were achieved
Outcome
A redesigned chat interface fully aligned with Better-Half.ai’s AI experience
Seamless integration with all existing backend systems
Support for new backend capabilities without architectural changes
Reliable real-time communication and authentication flows
A deployable, embeddable chat widget ready for multi-platform use
Impact
This project elevated Better-Half.ai’s chat experience into a production-grade, AI-aligned interface, while ensuring backend continuity, extensibility, and long-term scalability—bridging design, frontend engineering, and backend integration into a single cohesive solution.
