Modular Business Website Framework: Efficient Client Site Architecture

Role: Full-Stack Developer & UX Designer

Timeline: 8 hours (MVP) + 3-5 hours per deployment

Year: 2025-2026

Clients: DesignsByADino, Amy's Hen House, The Umbral Garden

Status: 3 live sites, framework ready for additional deployments

THE HOOK

Built a reusable website architecture that deploys fully-customized small business sites in 3-5 hours—handling e-commerce, bookings, galleries, and admin dashboards while maintaining unique brand identities across completely different industries.

THE CHALLENGE

After building several websites for small businesses and independent creators, I recognized a pattern: most small business sites need identical core functionality (products/services, booking, contact, about pages) but with completely different branding and content structures.

The problem with traditional approaches:

Custom development for each client: Days to weeks per site, high costs
Website builders (Squarespace, Wix): Limited customization, inflexible, ongoing subscription costs
Generic templates: Difficult to customize deeply, clients look cookie-cutter

I needed a solution that combined the flexibility of custom development with the efficiency of templates—something that could deploy professional sites in hours, not days, while maintaining complete design freedom.

THE APPROACH

Phase 1: Building the Foundation (MVP - 8 hours)

Database Architecture (1.5 hours)

Designed flexible PostgreSQL schema supporting multiple business models
Implemented Row Level Security policies for multi-tenant architecture
Created modular tables: gallery, shop_items, commissions, orders, site_settings
Built payment-processor-agnostic structure (easy to swap Square → Stripe → PayPal)

Core Pages & Features (3 hours)

Home, Gallery, Shop, Contact, About pages
Service/product display systems
Booking and commission request forms
Responsive navigation with mobile optimization

Admin Dashboard (3.5 hours)

Product/service management
Order tracking
Commission Kanban board
Gallery management

Phase 2: The Theming System

CSS Variable-Based Customization

Every visual element pulls from a single configuration:

css

@theme {
  --color-site-blue: #161854;
  --color-site-gold: #AAB8EE;
  --font-heading: "Georgia", serif;
  --font-body: "Segoe UI", system-ui, sans-serif;
}

Automatic Accessibility

Built a contrast calculation utility that ensures WCAG AA compliance automatically:

javascript

// Every component gets accessible text colors automatically
const heroBg = theme === "dark" ? "#333333" : "#FFFFFF";
const textColor = getTextColor(heroBg); // Auto-calculates contrast

Result: Complete visual rebranding without touching component code.

Phase 3: Rapid Deployments (3-5 hours per site)

Configuration Process:

Update site_settings table with brand colors and business info
Swap logo, favicon, and background pattern assets
Configure payment integration (Square credentials)
Set up email notifications (Resend templates)
Customize content structure and copy
Deploy to Vercel

Developer Experience

TypeScript for compile-time error catching
Version-controlled database migrations
Environment-based configuration
Comprehensive inline documentation

TECHNICAL CHALLENGES SOLVED

Challenge: Supporting both old single-image schema and new multi-image system without breaking existing sites.

Solution: Built backward-compatible component that gracefully handles both:

typescript

interface ShopItem {
  image_url: string;  // Legacy support
  images: ImageData[]; // New multi-image
}

// Component adapts automatically
{item.images?.length > 0 ? (
  <ImageCarousel images={item.images} />
) : (
  <Image src={item.image_url} />
)}

Challenge: Maintaining consistent theming while allowing complete visual customization.

Solution: CSS variables combined with automatic contrast calculation. Every component calculates accessible colors dynamically—no manual color tweaking needed.

Challenge: Payment processor flexibility without schema rewrites.

Solution: Processor-agnostic database design:

sql

CREATE TABLE orders (
  payment_id TEXT,
  payment_method TEXT NOT NULL DEFAULT 'square',
  UNIQUE(payment_id, payment_method)
);

Can swap payment providers without touching the schema.

Challenge: Image optimization at scale.

Solution: Sharp + WebP pipeline. Background images: 902KB → 48KB (94.7% reduction). Pattern images: 366KB → 36KB (90.2% reduction). Total savings: ~1.2MB per page load.

KEY LEARNINGS

Database Design Matters Early: JSONB fields for flexible data (images array, variant metadata) allowed adding features without breaking existing sites. The multi-image backward compatibility meant no migration headaches.

Performance Has a Budget: WebP conversion achieved 90-95% file size reductions. That 1.2MB saved per page load is noticeable on mobile connections—worth the upfront optimization time.

Configuration > Code: Moving site settings from environment variables to database enabled runtime theme updates without redeployment. This single decision made the framework viable.

RLS Policies Are Powerful: Supabase Row Level Security at the database level is more robust than application-layer checks, but debugging policies requires careful planning. Building them into the framework prevented security issues across all deployments.

Progressive Enhancement Works: Forms work without JavaScript, images lazy-load, modals dynamically import. These aren't theoretical—they're achievable with Next.js and improve real user experience.

Payment Integration Takes Time: Square's Web Payments SDK needed careful error handling. Building it once saved debugging hours on subsequent sites.

Type Safety Compounds: TypeScript caught dozens of errors that would have been runtime bugs. The upfront interface investment paid off across all three deployments.

Contrast Shouldn't Be Manual: The getTextColor() utility automatically ensures WCAG AA compliance, solving dark mode accessibility before it became a problem.

TECHNICAL TAKEAWAYS

This framework proves that modern web apps don't need heavyweight solutions—smart architecture with the right tools delivers professional results efficiently.

Core Principles Validated

Design Systems Scale: CSS variables + automatic contrast = consistent theming without intervention
Database-First Security: RLS policies prove more robust than application-layer checks
Performance Through Simplification: No UI library, WebP optimization, strategic memoization = faster loads
Flexibility Enables Growth: JSONB fields and processor-agnostic schemas support evolution without migrations

Applicability Beyond These Sites

This architecture works for any small business needing:

Portfolio/gallery showcase
E-commerce with inventory management
Service booking systems
Commission/project tracking
Client communication tools

The framework demonstrates that thoughtful architectural decisions create compound returns across multiple deployments.
