I will integrate a database or API into your existing website
Lautaro Manfred
About this gig
Your website looks great, but it's just sitting there no way to collect data, connect to your tools, or grow beyond a static page. Hiring someone to "rebuild everything" feels like overkill when all you actually need is to connect what you already have.
I'm Freud, a full stack developer specialized in integrating databases and APIs into existing websites no rebuilds, no starting over. I work with Supabase, custom REST APIs, and Python/FastAPI to add exactly the functionality you're missing:
- Contact forms, bookings, or signups that save to a real database
- User authentication and admin dashboards
- Connections to external APIs
- Payment integration (Stripe, Mercado Pago)
- Analytics and reporting features
Every integration is built to keep your existing site intact I add exactly what's missing, without touching what already works.
Ready to add real functionality to your site? Send me your website link and what you need connected I'll reply with a clear plan before we start.

Full stack developer specialized in fast, reliable web apps that don't break when you scale.
I build with Python/FastAPI on the backend and React/Vite on the frontend — but what you actually get is clean, maintainable code, a clear technical plan before any line is written, and a developer who can own your whole project or slot into your existing team without friction.
Tell me about your project and I'll map out exactly how I'd build it — no vague estimates, no surprises.
FAQ
Do I need to give you access to my website?
"Yes, I'll need access to your hosting/codebase (or a staging copy) to safely add the integration without breaking your live site. I'll walk you through exactly what I need before we start.
Will this break my existing website?
No — my approach is to add functionality without touching what already works. I always test in a safe environment before anything goes live.
What platforms can you integrate with?
I work with Supabase, custom REST APIs, and most modern backends. If you're not sure whether your site is compatible, send me the link and I'll confirm before you order.
My site was built with a website builder (Wix, Squarespace, etc.) — can you still integrate a database or API?
It depends on the platform's flexibility — some builders are very limited for custom integrations. Message me with details about your site and I'll tell you honestly if it's possible before you order.
How long does an integration usually take?
It depends on complexity — a single form-to-database connection can take 2-3 days, while a full backend setup with authentication and a dashboard takes about a week. Check my package options for specifics.
Do you offer ongoing support after the integration is live?
Yes, I'm available for fixes, updates, or adding more integrations later if your needs grow.
