Introduction
As a developer, I've always believed in working smarter, not harder. When I decided to build a professional portfolio site with a comprehensive content management system, I knew I wanted something modern, maintainable, and powerful—but I didn't want to spend weeks reinventing the wheel.
Enter AI-assisted development. What would have traditionally taken weeks of research, trial and error, and countless Stack Overflow searches was accomplished in a matter of hours with the help of GitHub Copilot's AI agent. Here's the story of how we built a production-ready CMS system together.
The Vision
I wanted a portfolio site that was:
- Fast and Modern: Static site generation for optimal performance
- Content-Friendly: Easy for me to write and publish articles
- Designer-Controlled: A beautiful, responsive design system
- Feature-Rich: Admin dashboards, content management, automated workflows
- Developer-Friendly: Clean code, maintainable architecture, excellent documentation
- Flexible: Modular features I could toggle on/off easily
Traditional CMS platforms like WordPress felt too heavy. Headless CMSs required complex backends. I wanted something in between—a static site with dynamic content management capabilities.
The Tech Stack
Together with AI assistance, we chose a powerful yet lightweight stack:
Core Technologies
- Eleventy 3.1.2: Static site generator with incredible flexibility
- Nunjucks: Templating engine for component-based layouts
- Vanilla CSS: Custom design system (no framework bloat)
- Netlify CMS (Decap CMS): Git-based content management
- Netlify Identity: Authentication for admin sections
- GitHub Actions: Automated deployment workflows
The AI Advantage
What made this project remarkable was how AI assisted at every phase:
- Architecture Decisions: AI helped evaluate pros/cons of different approaches
- Code Generation: Boilerplate and repetitive code written instantly
- Best Practices: Following modern web development standards automatically
- Problem Solving: Complex issues like git submodule integration solved quickly
- Documentation: Comprehensive docs generated alongside code
What We Built Together
Phase 1: Foundation (Hour 1)
We started with the Eleventy configuration. The AI helped set up:
- Collections system for blog posts and projects
- Custom filters for dates, excerpts, and reading time
- Passthrough copying for assets
- Draft filtering based on configuration
Key Learning: AI excels at configuration files. Instead of reading docs for hours, I described what I needed, and it generated a complete, working Eleventy config.
Phase 2: Design System (Hour 2)
Next came the CSS. I wanted a comprehensive design system with:
- CSS variables for theming
- Automatic dark mode support
- Responsive layouts
- Reusable components
The AI generated over 1,000 lines of production-ready CSS with:
- Complete color palette with dark mode variants
- Typography scale (xs to 4xl)
- Spacing system (4px to 96px)
- Card components with hover effects
- Grid layouts that adapt to content
- Proper text overflow handling
Key Learning: Describing design intent in natural language produced better results than trying to write CSS from scratch. The AI understood concepts like "make cards that don't overflow" and implemented proper word wrapping everywhere.
Phase 3: Page Layouts (Hours 3-4)
We built the core pages:
- Homepage: Hero section, services showcase, recent content
- Blog: Article listings with tag filtering
- Projects: Portfolio showcase with tech stack display
- Work with Me: Comprehensive services page with pricing, process, FAQ
Each page was componentized with reusable Nunjucks layouts. The AI maintained consistency across all templates.
Key Learning: Breaking down page requirements into components made the AI incredibly effective. "Create a work-with-me page with benefits grid, services section, and FAQ" produced exactly what I envisioned.
Phase 4: Admin Dashboard (Hour 5)
This is where things got interesting. I wanted a custom admin interface to toggle features without editing config files.
The AI built:
- Authentication-protected admin panel
- Feature toggle switches
- Real-time config updates
- Visual feedback for changes
All integrated with Netlify Identity for security.
Key Learning: AI can build complete admin interfaces quickly. What would have been a day's work (authentication, UI, state management) was done in an hour.
Phase 5: Netlify CMS Integration (Hour 6)
We integrated Decap CMS for content editing with a visual interface. This required:
- CMS configuration with proper collections
- Git Gateway backend setup
- Authentication integration
- Custom field configurations
Challenge Encountered: Git submodules don't work with Netlify CMS's git-gateway backend.
AI Solution: Implemented a dual blog folder system—one submodule for GitHub management, one main folder for CMS access. Eleventy reads from both. Brilliant workaround.
Phase 6: Automated Deployments (Hour 7)
The final piece was automation. I wanted to manage blog content in a separate repository but have changes automatically deploy.
The AI created:
- GitHub Actions workflow in main repo to update submodule references
- GitHub Actions workflow in blog repo to trigger main repo updates
- Proper webhook configuration
- Documentation for token setup
Key Learning: Complex automation workflows that would require reading multiple documentation sources were generated with explanations. The AI understood the entire git submodule deployment pipeline.

Lessons Learned: Working with AI
What AI Excels At
- Boilerplate Generation: Creating project structures, config files, initial setups
- Pattern Recognition: Maintaining consistency across similar components
- Documentation: Generating comprehensive docs alongside code
- Problem Solving: Finding solutions to complex integration challenges
- Best Practices: Applying modern standards automatically
What Still Requires Human Input
- Vision: Defining what you want to build
- Design Decisions: Aesthetic choices and UX flows
- Priority: Deciding what features matter most
- Testing: Verifying everything works as expected
- Content: Writing meaningful articles (like this one!)
The Collaboration Sweet Spot
The best results came from:
- Clear Requirements: Describing what I wanted in detail
- Iterative Refinement: Building in phases, testing each part
- Strategic Questions: Asking for options and trade-offs
- Trusting the Process: Letting AI handle implementation details
Conclusion
Building this professional CMS portfolio with AI assistance was a revelation. What would traditionally take weeks of work—research, coding, debugging, documentation—was accomplished in hours.
The key wasn't just speed; it was the quality of the output. The code is clean, well-documented, and follows best practices. The architecture is solid and maintainable. The features are production-ready.
Does this mean developers are obsolete? Absolutely not.
AI is a power tool, like a compiler or IDE. It amplifies your capabilities but doesn't replace your judgment, creativity, or expertise. You still need to:
- Know what you want to build
- Understand what the AI generates
- Make architectural decisions
- Test and validate everything
- Maintain and evolve the system
But with AI assistance, you can focus on the creative and strategic aspects of development while letting AI handle the mechanical parts.
Try It Yourself
