Mustafa G.
Product Engineer | SaaS, Stripe, Payments, APIs & AI | React/Node.js
⚡ SAAS | AI INTEGRATION | STRIPE | FINTECH | REACT | NODE.JS | MOBILE APPS | WEB DEVELOPMENT If your SaaS platform is losing revenue due to failed payments, broken billing logic, or an AI integration that doesn't actually work in production I can fix that. I build and ship production-ready SaaS platforms, AI-powered tools, mobile apps, and high-performance websites that handle real users and real money. Not demos. Not prototypes. 🎯 Where I make the biggest impact: 🔴 Stripe billing that breaks under load or edge cases 🔴 AI features that fail silently in production 🔴 SaaS platforms that work locally but fall apart at scale 🔴 Mobile apps that need to ship to both App Store and Play Store 🔴 Websites that look good but don't convert or perform 🔴 Webhook handling that misses events and causes revenue loss 🚀 What I deliver: 💎 End-to-end SaaS platforms with subscription billing and AI integrations 💎 Stripe Connect, Billing, and webhook architecture built to scale 💎 Claude/OpenAI integrations that actually work in production 💎 React Native mobile apps published to both stores 💎 Fast, modern websites and web apps built for performance and conversions 💎 Clean, documented code your team can maintain after handoff With 8 years of hands-on experience, I've seen what breaks at scale, what kills conversions, and what actually moves the needle for a growing business. 💬 Send me a message and let's talk about what you're building.
