Merhaba,
VPN satış sistemi geliştirme projeniz için deneyim ve uzmanlığımı sunuyorum. Daha önce benzer projelerde API entegrasyonları, ödeme sistemleri (NOWPayments, CoinsPaid), WhatsApp botları (Baileys, open-wa) ve kullanıcı panelleri geliştirdim. Bu projede tüm modülleri baştan sona üstlenebilirim.
Projeyi 10-12 gün içinde, aşamalı testlerle teslim edebilirim. Ayrıca uzun vadeli bakım ve güncellemeler için de destek sağlayabilirim.
Referans sistemi ve ödeme altyapısının entegrasyonunda aklınızda belirli bir ödül mekanizması var mı? Detaylandırabilirseniz, sistemi daha iyi optimize edebilirim.

Integrate Cloudflare DNS with SSL (Let’s Encrypt) and domain routing
Develop WhatsApp bot using Baileys with webhook triggers post-payment
Integrate NOWPayments API for crypto/card handling with auto-conversion and webhook triggers
Build referral logic (unique links, rewards, CoinsPaid payout trigger)
