I will do API integration, contact form setup and website speed optimization
Sumera Yaseen
Sobre este Serviço
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.

Hi! I’m a front-end developer who fixes and builds fast, responsive websites. I solve HTML, CSS and JavaScript bugs, mobile responsive issues, React and Next.js errors, and MongoDB or API problems. I also convert Figma designs into pixel-perfect React or Next.js landing pages with Tailwind CSS, set up contact forms, connect APIs, and improve page speed and Core Web Vitals. You get clean, tested code, clear updates and fast replies. Message me before ordering and I will check your issue for free.

Perguntas frequentes
Which websites do you support?
Custom HTML/CSS/JS sites and React/Next.js apps. For WordPress, Wix or Shopify, message me first.
Can you guarantee a 100 PageSpeed score?
No honest developer can promise a fixed score, because hosting, third-party scripts and content affect it. I fix the issues PageSpeed Insights flags and give you a before/after report.
Are my API keys safe?
Yes. Keys go in environment variables or server-side functions, never in public front-end code. I can use test/sandbox keys while I work.
Do I need my own accounts (EmailJS, Stripe, etc.)?
Yes. The service accounts stay in your name. I can guide you through creating them if needed.
