Sajjad Ali
About this gig
Need an API wired into your React, Next.js, or vibe-coded app? I connect frontend to backend cleanly, whether it's authentication, payments, AI, or any third-party service.
I build production-grade integrations, not quick hacks, with proper error handling, environment configuration, and secure data flow every time.
What I integrate:
- Payment APIs (Stripe, PayPal)
- Authentication (Firebase, Supabase, JWT)
- AI APIs (OpenAI, Gemini, Claude, LangChain)
- Any REST or GraphQL API into React, Next.js, or Python applications
- Webhooks and real-time data synchronization
Why Me?
- Hands-on experience building production APIs with Django REST Framework and FastAPI
- Full-stack expertise. I connect both frontend and backend correctly
- Clean, documented, and maintainable code
- Fast turnaround with clear updates throughout the project
Message me your API and app details, and I'll confirm the project scope before you order.
Let's get it integrated right the first time!
