Website Refactoring Summary

Date: November 25, 2025 Status: ✅ Complete Build Status: ✅ Successful (1.83 seconds)

Overview

Completed comprehensive refactoring of the Jekyll portfolio website based on architectural code review findings. All critical and high-priority issues have been addressed, resulting in improved maintainability, performance, and security.

🎯 Completed Tasks

✅ 1. CSS Extraction to Sass (CRITICAL)

Impact: Massive improvement in maintainability and performance

Before:

1800+ lines of inline CSS across multiple files
No caching possible
Difficult to maintain
Large HTML payload

After:

Organized Sass architecture with 19 partial files
Single compiled CSS file (41KB, cached by browsers)
Component-based organization
Clean separation of concerns

Structure Created:

_sass/
├── base/
│   ├── _variables.scss (CSS custom properties)
│   └── _reset.scss (Global resets)
├── components/
│   ├── _navigation.scss
│   ├── _hero.scss
│   ├── _skills.scss
│   ├── _projects.scss
│   ├── _blog.scss
│   ├── _contact.scss
│   ├── _footer.scss
│   └── _buttons.scss
├── layouts/
│   ├── _home.scss
│   ├── _post.scss
│   └── _page.scss
└── utilities/
    ├── _helpers.scss
    └── _responsive.scss

Files Modified:

_layouts/default.html - Removed ~786 lines of inline CSS
_layouts/home.html - Removed ~612 lines of inline CSS
_layouts/post.html - Removed ~398 lines of inline CSS
_includes/skills-chart.html - Removed ~152 lines of inline CSS
_includes/navigation.html - Removed ~66 lines of inline CSS
_includes/svg-icons.html - Removed ~162 lines of inline CSS

Performance Impact:

First page: Downloads CSS once (cached)
Subsequent pages: 0KB CSS downloads
~50-70KB savings per page after initial load

✅ 2. JavaScript Consolidation (CRITICAL)

Impact: Better maintainability and organization

Before:

4+ separate DOMContentLoaded listeners
JavaScript scattered across layouts and includes
No central initialization
Difficult to debug

After:

Single organized module in /assets/js/main.js
Centralized initialization
Namespaced functionality
Clear module structure

Modules Created:

App.navigation - Mobile menu, smooth scrolling, scroll effects
App.skills - Skill bar animations
App.forms - Form validation and submission
App.projects - Project card animations
App.accessibility - Focus trap, ARIA announcements
App.performance - Lazy loading optimizations

Key Features:

RequestAnimationFrame throttling for scroll performance
Proper error handling
Feature detection
Accessibility enhancements

✅ 3. Projects Data File (HIGH PRIORITY)

Impact: Much easier content management

Created: _data/projects.yml

Before:

Hardcoded project data in home.html
200+ lines of repetitive HTML
Difficult to add/update projects

After:

Clean YAML data file
Single Liquid loop in template
Easy to add new projects
Consistent structure

Example:

- name: PushTo100
  app_id: 6746961563
  website: https://www.pushto100.com
  platforms: [iPhone, iPad, Apple Watch]
  tech_stack: [SwiftUI, HealthKit, CloudKit, WatchKit]

✅ 4. Form Enhancements (HIGH PRIORITY)

Impact: Better security and user experience

Improvements:

✅ Honeypot field (_gotcha) for spam protection
✅ Client-side validation with pattern matching
✅ Min/max length validation
✅ ARIA attributes for accessibility
✅ Error message regions
✅ Custom form subject
✅ Better input constraints

Example:

<!-- Honeypot (hidden) -->
<input type="text" name="_gotcha" style="display:none">

<!-- Validated input -->
<input
  type="text"
  name="name"
  pattern="[A-Za-z\s\-']+"
  minlength="2"
  maxlength="100"
  aria-required="true"
  required
>

✅ 5. Google Analytics Upgrade (HIGH PRIORITY)

Impact: Future-proof analytics with privacy features

Before:

Deprecated Universal Analytics (analytics.js)
No privacy features
Will stop working July 2023

After:

Google Analytics 4 (GA4) with gtag.js
IP anonymization enabled
Secure cookie flags
GDPR-friendly configuration

✅ 6. Security Improvements (HIGH PRIORITY)

Impact: Better protection against common vulnerabilities

Implemented:

✅ Content Security Policy (CSP) meta tag
✅ Resource hints for third-party services
✅ Viewport fit for modern devices
✅ Reduced font weights (400, 600, 700 only)
✅ rel="noopener noreferrer" on external links
✅ Created SECURITY.md with best practices

CSP Policy:

default-src 'self';
script-src 'self' https://www.googletagmanager.com https://formspree.io;
style-src 'self' https://fonts.googleapis.com;
font-src 'self' https://fonts.gstatic.com;
img-src 'self' data: https:;
connect-src 'self' https://formspree.io https://www.google-analytics.com;
frame-ancestors 'none';

✅ 7. CSS Variable Cleanup

Impact: Eliminated code duplication

Fixed:

Removed unused .dark-theme class (96 lines)
Fixed scroll-behavior to respect prefers-reduced-motion
Replaced hardcoded colors with CSS variables
Centralized all theming in _variables.scss

✅ 8. Performance Optimizations

Scroll Performance:

Implemented requestAnimationFrame throttling
Passive event listeners for better performance
Eliminated layout thrashing

Font Loading:

Reduced from 5 weights to 3 (400, 600, 700)
Added display=swap for better perceived performance
Preconnect to Google Fonts for faster loading

Resource Hints:

<link rel="preconnect" href="https://fonts.googleapis.com">
<link rel="preconnect" href="https://formspree.io">
<link rel="dns-prefetch" href="https://www.google-analytics.com">
