Fixthisbug.de

Let's be transparent: building an MVP in 2024 looks different than it did five years ago. Here's how I leveraged modern AI tools to build FixThisBug.de in just one week.

Day 1-2: Foundation and Setup

- Used Next.js 15 with App Router for the foundation

- Leveraged Windsurf IDE's AI pair programming for rapid prototyping

- Set up authentication and basic UI components using shadcn/ui

- Added supabase for fast auth and data storage

- Cursor AI helped generate boilerplate code and basic layouts

Day 3-4: Core Functionality

- Built the code analysis engine with AI assistance

- Implemented vLLM setup on selfhosted gpu server

- Implemented the explanation generator

- Used Windsurf's code generation for repetitive tasks

- Added bilingual support (EN/DE) using next-intl

Day 5-6: Polish and Testing

- Enhanced UI/UX with Tailwind CSS

- Added error handling and input validation

- Implemented rate limiting and user quotas

- Set up hosting on German servers for GDPR compliance

Day 7: Launch Prep

- Created landing page content

- Set up analytics and monitoring

- Added documentation and help sections

- Deployed and tested in production

Key Takeaways

1. AI as a Multiplier: Tools like Windsurf and Cursor didn't replace thinking - they accelerated implementation. They're best at:

- Generating boilerplate code

- Suggesting implementation patterns

- Catching potential issues early

- Handling repetitive tasks

2. Focus on Differentiation: I spent most time on what makes FixThisBug unique:

- Educational explanations

- Bilingual support

- Privacy-focused architecture

3. Don't Skip the Basics: Even with AI help, you need:

- Clear product vision

- Solid architecture decisions

- Security considerations

- User-focused design

Tools That Made It Possible

- Windsurf IDE for AI pair programming

- Cursor for rapid code generation

- ChatGPT for content creation

- Selfhosted Ollama instance for content creation

- Vercel for deployment

The key was using AI tools strategically - not as a crutch, but as accelerators for well-thought-out features. They handled the routine work while I focused on the core value proposition.

Remember: AI tools are incredibly powerful, but they're just that - tools. The vision, architecture decisions, and user experience still need human insight.

As a software development consultant with over 8 years of experience, I've spent countless hours with my product team helping developers debug their code.

Often junior developers find the solution on Stack Overflow, but they didn't understand why it worked. They just copied the code and moved on. I realized this was a missed learning opportunity – one that happens thousands of times daily across the development community.

That's when the idea for FixThisBug.de was born. I wanted to create something that wouldn't just fix bugs, but would explain them in a way that helps developers grow. The goal wasn't to be another AI code fixer, but rather a debugging mentor that combines immediate solutions with educational insights.

What now makes FixThisBug.de different is its dual approach: instant fixes paired with clear explanations. We don't just tell you to make your HashMap keys immutable – we explain why mutable keys break things, complete with examples and best practices.
