AI SaaS Developer A-Z | MVP Build & Rescue | Next.js, Supabase, Stripe
🚀 I build AI SaaS products from idea to paying users, and rescue the ones that got stuck. Lean MVPs go live in days, full products in weeks, never months. Hi, I'm Ivelin. Founders hire me to take an idea, an MVP, or a half-finished app and turn it into a secure, production-ready product that customers can sign up and pay for. One developer, everything covered from A to Z, so you don't need to hire a team. Here's what you get: ✅ SaaS MVP built end to end: architecture, backend, frontend, auth, Stripe payments, SEO + AI SEO, deployment ✅ AI features that work in production, not demos: agents, RAG, semantic search, Claude, Gemini, and OpenAI ✅ Rescue for AI-built apps (Lovable, Bolt, v0, Cursor, Claude Code): security fixes, performance optimization, codebase cleanup, real launch ✅ Enterprise-grade security by default: RLS, role-based access, audit logs Why founders pick me: ⚡ My fastest MVP went from brief to live in 24 hours. 🏢 Trusted by Fortune 500 and global enterprises (Pfizer, WindTre, Randstad), with platforms serving millions of users. 🤝 A-to-Z solutions: from first call to launch and clean handover, one person owns the whole result. My process: 1. Send me your idea, app, or stuck codebase. 2. I'll record a FREE personalized video audit with a concrete plan for improvement. 3. I build and fix what's needed, we review everything together, and you start making money. If you're looking for one developer who covers everything from A to Z and ships fast, send me a message. Let's turn your idea into recurring revenue. - Ivelin I. ⭐⭐⭐⭐⭐
