Now let me check the email template to see how to add the WhatsApp field:

I can see the email template already has support for WhatsApp (senderPhone field). Now I'll add the WhatsApp number input field to the contact form:

Now I'll update the API route to handle the optional WhatsApp number:

I've successfully added the WhatsApp number field to your contact form. The new input field is optional for clients but will be included in the email notification if provided. When a client submits their WhatsApp number, it will appear in the email template and in the footer's "Next Steps" section showing you can contact them via WhatsApp. The field uses the tel input type for better mobile UX and maintains the same minimalist styling as the rest of the form.

Now let me add the Reviews component to the main page:

I've added a client reviews section to your portfolio website. The new Reviews component features a grid of client testimonials with star ratings, client names, roles, and company affiliations. The reviews section is placed after the portfolio and before contact, providing social proof that builds trust with potential clients. It uses the same dark theme styling with gradient backgrounds and orange accent colors to maintain consistency with the rest of your site.
