Architecture Deep Dive
The system architecture follows a modern, full-stack approach with several key components:
1. Builder Application
The website builder is built with Next.js 15 using the App Router and serves as the command center for users. It includes:
- Trade-specific template system - Dynamic component rendering based on business type with specialized sections for different trades
- Live preview functionality - Real-time preview using React Server Components that mirror the published site exactly
- Form-based editing - Simplified editing through structured forms rather than complex WYSIWYG editors
- AI-powered autofill - OpenAI integration that suggests content based on business name and trade type
- Image optimization pipeline - Automatic image processing through Supabase Storage with WebP conversion and responsive sizing
One interesting technical challenge was creating a builder that felt simple while offering trade-specific customizations. I implemented a dynamic component system that conditionally renders different form fields and preview sections based on the selected trade, keeping the interface clean while maintaining powerful functionality.
2. Subdomain Routing & Site Rendering
The published sites use a sophisticated subdomain routing system:
- Custom middleware - Intercepts requests to subdomains and routes them to the appropriate site renderer
- Dynamic site lookup - Uses Supabase to find published websites by subdomain in real-time
- Server-side rendering - Each published site is rendered server-side for optimal SEO and performance
- Automatic SEO optimization - Generates meta tags, schema markup, and structured data based on business information
- Progressive Web App features - Includes manifest files and service workers for app-like experience
The routing system uses Next.js middleware to detect subdomains like "smith-plumbing.buildyourtradesite.com" and dynamically rewrite the request to render the appropriate site content. This allows each business to have their own branded URL while maintaining a single codebase.
3. Database Architecture
The data layer uses Supabase (PostgreSQL) with a carefully designed schema:
- Relational data model - Normalized tables for users, websites, business information, and content
- Row Level Security (RLS) - Ensures users can only access their own data
- Real-time subscriptions - For live preview updates during editing
- Automatic backups - Built-in point-in-time recovery through Supabase
- JSON columns - For flexible storage of trade-specific configurations and content
4. AI Content Assistant
The AI component was particularly challenging to implement effectively:
- Trade-specific prompt engineering - Creating specialized prompts for different trades
- Content validation pipeline - Ensuring AI-generated content meets quality standards
- User feedback loop - Learning from user edits to improve future suggestions
I implemented a hybrid approach that combines pre-written industry-specific templates with OpenAI's text generation capabilities. This provides more reliable, targeted content than using raw AI output alone.
Database Schema Design
The PostgreSQL database schema balances flexibility with structure using a normalized approach:
-- Core tables structure
CREATE TABLE websites (
id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
user_id UUID REFERENCES auth.users(id),
business_name TEXT NOT NULL,
trade_type TEXT NOT NULL,
subdomain TEXT UNIQUE,
is_published BOOLEAN DEFAULT false,
business_info JSONB,
site_config JSONB,
created_at TIMESTAMPTZ DEFAULT NOW(),
updated_at TIMESTAMPTZ DEFAULT NOW()
);
CREATE TABLE website_pages (
id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
website_id UUID REFERENCES websites(id) ON DELETE CASCADE,
page_type TEXT NOT NULL,
content JSONB NOT NULL,
is_active BOOLEAN DEFAULT true,
created_at TIMESTAMPTZ DEFAULT NOW()
);
CREATE TABLE project_gallery (
id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
website_id UUID REFERENCES websites(id) ON DELETE CASCADE,
title TEXT NOT NULL,
description TEXT,
images JSONB,
is_cover_image BOOLEAN DEFAULT false,
created_at TIMESTAMPTZ DEFAULT NOW()
);
-- Row Level Security policies
ALTER TABLE websites ENABLE ROW LEVEL SECURITY;
CREATE POLICY "Users can only access their own websites"
ON websites FOR ALL USING (auth.uid() = user_id);I used PostgreSQL's JSONB columns to handle the varied structure needs across different trades while maintaining ACID compliance and the ability to query nested data efficiently. The RLS policies ensure complete data isolation between users.
Frontend Architecture
The builder interface posed interesting technical challenges:
Component Design System
I implemented a hierarchical component system:
- Core components - Foundational UI elements (buttons, inputs, cards)
- Composite components - Combinations of core components (form sections, image galleries)
- Page templates - Full page layouts combining composite components
- Trade-specific components - Specialized elements for particular trades (service area maps for plumbers, project calculators for contractors)
This hierarchy allows for consistent design while accommodating trade-specific needs.
State Management
Given the complexity of the builder, I chose a lightweight but powerful state management approach:
- Zustand - For global application state with minimal boilerplate
- React Context - For theme preferences and authentication state
- React Hook Form - For form state management with validation
- Supabase real-time - For live preview updates and collaborative editing
- Optimistic updates - For responsive user experience during saves
Performance Optimization
Several techniques ensure the builder remains fast and responsive:
- Code splitting - Loading only needed components
- Virtualization - For handling large lists of content items
- Memoization - Preventing unnecessary re-renders
- Asset preloading - For common templates and components
Deployment Architecture
The deployment architecture leverages Vercel's edge network and Supabase's global infrastructure:
- Main application - Deployed on Vercel with automatic deployments from Git
- Edge functions - API routes run on Vercel's edge network for low latency
- Database - Supabase PostgreSQL with global read replicas
- File storage - Supabase Storage with CDN for optimized image delivery
- Custom domains - Subdomain routing handled by Vercel's edge middleware
This architecture provides global performance, automatic scaling, and zero-downtime deployments. The edge-first approach ensures that both the builder and published sites load quickly worldwide.
SEO Implementation
SEO is critical for trade businesses, so I implemented several specialized features:
- Local SEO optimization - Automatic generation of location-specific content and schema markup
- Service schema markup - Structured data for services offered
- NAP consistency - Ensuring consistent Name, Address, Phone number across all pages
- Mobile optimization - Prioritizing mobile performance for better search rankings
- Semantic HTML structure - Using appropriate heading tags and semantic elements
Each generated site includes built-in Google Business Profile integration, helping trades rank in local map results—crucial for service-area businesses.

Challenges and Solutions
The development process wasn't without obstacles. Here are some key challenges and their solutions:
Challenge 1: Trade-Specific Content Variation
Problem: Different trades need vastly different content structures and terminology.
Solution: I implemented a "content dictionary" system that maps generic content types to trade-specific implementations. This allows the core system to remain consistent while the presentation layer adapts to each trade's unique needs.
Challenge 2: User Technical Limitations
Problem: Many tradespeople have limited technical experience and were struggling with traditional WYSIWYG editors.
Solution: I developed a simplified "guided editing" approach that uses form-based inputs rather than direct content editing, with visual previews showing the impact of each change.
Challenge 3: Subdomain Routing Complexity
Problem: Each published site needed its own subdomain while maintaining a single codebase and ensuring fast performance.
Solution: I implemented Next.js middleware that intercepts subdomain requests, looks up the website in Supabase, and dynamically rewrites the request to render the appropriate site content server-side.
Challenge 4: Real-time Preview System
Problem: Users needed to see exactly how their published site would look while editing, without the complexity of a traditional WYSIWYG editor.
Solution: I created a preview system that uses the same React components as the published sites, with Supabase real-time subscriptions updating the preview instantly as users make changes in the form-based editor.
