About this gig

Need your website to send form messages reliably, pull data from an API, or simply load faster? I connect custom HTML and React sites to the services you rely on, then tune performance for better Core Web Vitals.


Integrations I handle:

- Contact forms with email delivery (EmailJS, Formspree, Nodemailer, SMTP)

- Spam protection with reCAPTCHA plus validation

- REST API connections: fetch, Axios, auth tokens, error states

- Third-party services such as Stripe checkout, Google Sheets, Mailchimp

- Simple content edits like text, images, links


Speed improvements:

- Image compression, WebP, lazy loading

- Code splitting, minified CSS/JS, removed unused scripts

- Fixes for LCP, CLS, INP issues flagged by PageSpeed Insights

- Before/after report so results are clear


Why choose me:

- Custom code and React expertise, not page builders

- Secure handling of keys through environment variables

- Fast replies, clear updates


How it works:

1. Tell me what needs connecting or which pages feel slow

2. I review your site and confirm the plan

3. Work is tested, then delivered with notes

4. Revisions until it runs as agreed


Message me first and I will check your site for free.
