### 🤖 Transparency — AI-Assisted Development

I believe in being fully transparent with my clients.

This project was built using AI-assisted development — specifically, I used Claude (by Anthropic) as a coding assistant throughout the process. This is a modern, professional workflow used by developers worldwide to increase speed, reduce bugs, and maintain clean code standards.

What this means for you:

- The code is reviewed, tested, and understood by me — not blindly copy-pasted

- All architecture decisions, design choices, and feature selections were made by me

- AI helped write boilerplate faster and catch edge cases — like a very fast pair programmer

- The final result is held to the same quality standard as hand-written code

- I can explain, modify, and extend any part of this codebase

This is no different from a developer using GitHub Copilot, Cursor, or any other AI tool — which is now standard industry practice.
