Custom Captcha Implementation

I'm in need of a skilled developer who can implement a Custom Captcha on my website. The Captcha should involve image recognition, text-based challenges, and puzzle-solving components.

Ideal Skills:
- Proficiency in web development
- Experience with creating and implementing Captchas
- Knowledge in image recognition technology
- Strong problem-solving skills

I'm looking for a professional who can ensure the Captcha is not only secure but also user-friendly and effective in preventing bots.
