Finalize and Deploy AI-Powered Web App (Next.js + Firebase + Stripe + MercadoPago)
Budget: $30 – $250 USD
? DESCRIPTION TO POST:
I'm looking for a reliable and experienced developer to finalize and deploy a nearly completed web app called InstaBrief.
The core functionality is already implemented. What’s needed now is someone to connect the API keys, validate payment flows, test all features, and complete deployment.
✅ What’s already done:
Fully functional frontend in Next.js + Tailwind CSS
AI summary feature using OpenAI
Neural voice generation using ElevenLabs with MP3 download
Public /demo page with free usage limit (session-based)
Admin panel protected by Google login (Firebase Auth)
Payment integration with Stripe (USD) and Mercado Pago (PIX & credit card in BRL)
Feedback form saved in Firestore
? What’s left to complete:
Insert all API keys in .env.local (I will provide them)
Connect and validate Stripe & Mercado Pago checkout flows
Deploy the project to Vercel
Test all features live (AI summary, voice, MP3, feedback, payment, usage limit)
Add final SEO/meta tags and favicon
Provide minimal documentation for future maintenance
? Requirements:
Experience with Next.js projects in production
Comfortable working with Firebase (Auth + Firestore)
Experience integrating Stripe and/or Mercado Pago
Ability to test and ensure all features work properly before delivery
⏱️ Estimated Time:
This is a clearly defined task with limited scope.
A professional with experience can complete this in 6 to 8 hours.
Proposals above that must come with a clear technical justification.
? When applying, please include:
Portfolio with similar projects
Your actual estimated time to deliver
Fixed price to complete the work
