Need a shippable no-code app — not a prototype that breaks on the first real user? I build production-ready SaaS MVPs, marketplaces, and internal tools using Lovable, VibeCode, and Supabase, in weeks, not months. I'm the founder of Dapper No-Code and Special Projects Director at ScaleLogix.ai, where I lead technical scoping on enterprise no-code initiatives. Since 2020 I've delivered 100+ projects and $250K+ in client work — from fintech ROSCA platforms to aviation crew networks — and I host The No-Code Advantage podcast. I work U.S. hours, respond fast, and tell you when an idea needs to be cut, not just when to build more. Here's what I build: 🚀 SaaS MVPs with Stripe payments and Supabase backends 🏪 Two-sided marketplaces and client portals (multi-tenant, multi-role) 🛠 Internal tools and admin dashboards that replace 3–5 disconnected tools 📱 Mobile apps for iOS and Android — no native code required 🔄 Platform migrations from GoodBarber, legacy Adalo, or any stalled vibe-coded build 🔍 Code audits and rescues for AI-generated apps that broke under real users I handle the unglamorous work most no-code developers avoid: payment edge cases, multi-role access, complex schemas, and data migrations. Recent builds include an aviation crew social network with role-based permissions, a food-service platform with Supabase admin panel, an Africa-focused freelance marketplace with Moolre payment integration, a nightclub song-request app with real-time DJ queue, and a dispute-voting platform with Stripe subscriptions. Recurring hosting and support contracts available after launch. Send me a message with a quick description of what you're building. I'll respond within a few hours with honest scoping feedback — no sales pitch.
