I will integrate stripe, supabase, firebase, or any API into your app
Ali Raza
About this gig
Your app is only as powerful as the systems behind it.
When payments fail, APIs don't connect, authentication breaks, or your database isn't properly wired, I build and fix the backend layer that keeps everything working together.
I integrate Stripe, PayPal, Supabase, Firebase, authentication systems, and REST/GraphQL APIs into existing web and mobile applications without unnecessary rebuilds.
What I handle:
Stripe & PayPal payments, subscriptions and webhooks
Supabase & Firebase backend integration
OAuth, JWT & social authentication
REST & GraphQL API integrations
Webhook configuration & third-party services
Deployment setup with Vercel, Netlify or AWS
Backend architecture, security & performance
Whether you need one critical integration or a complete backend build-out, I work directly with your existing codebase and focus on a reliable, scalable setup.
Send me what you're trying to connect, and I'll scope the right solution before you order.
