// How to build Region-Wise Resume Builder & AI Interview Prep Platform
Next.js + Supabase gives the partial team a fast, full-stack setup with built-in auth and real-time DB, minimizing DevOps overhead for a seed-stage product. OpenAI GPT-4o is the most practical choice for region-aware resume tailoring and mock interview generation without training custom models. Razorpay covers the likely-dominant Indian user base while Stripe handles international regions, aligning with the region-wise positioning.

## What to build in the MVP
-User authentication (email/password + Google OAuth)
-Region selector (e.g., India, US, UK, Middle East, Canada) that adjusts resume format and norms
-AI-powered resume builder with region-specific templates and content suggestions (GPT-4o)
-Resume export as PDF with region-appropriate layout
-AI mock interview module: role + region input → generates 10 tailored Q&A pairs with model answers
-Basic subscription plans (Free tier with limits, Pro tier with full AI access)
-Razorpay payment integration for INR subscriptions
-Admin dashboard: user list, subscription status, revenue overview, AI usage stats
-Usage-based AI rate limiting per plan tier

## Engineering risks to plan for
!AI cost bleed: GPT-4o calls for resume suggestions + interview Q&A generation can burn through seed budget quickly — strict per-plan rate limiting and response caching are non-negotiable from day one
!Partial team risk: if AI/backend expertise is missing from the current team, the OpenAI integration + PDF generation pipeline will become a bottleneck and delay the ASAP timeline
!Region accuracy gap: 'region-wise' differentiation is your core value prop — if the AI prompts are not deeply tuned per region (e.g., CV format for UAE vs resume for US), the product will feel generic and lose its USP
!Scope creep on AI features: auth + payments + admin + AI integrations is a heavy MVP for a seed budget — any addition risks blowing the timeline; defer voice interview and ATS scoring firmly
!Payment compliance: if targeting Middle East or US users at launch, Razorpay alone won't suffice — confirm target regions before launch to avoid last-minute Stripe integration scramble
