Vibe-coded Lovable, Base44, Bolt or Cursor app breaking with real users? I fix sign-in, Supabase RLS, Stripe payments and deploys, or migrate it to code and cloud you own. Base44 Architect Partner. I led 2 Base44-to-AWS migrations and 3 app rescues. I'm Ahmed Hassan Yaseen, a full-stack developer since 2020 and the founder and CEO of StacksMesh. I lead engineering and product there, and my StacksMesh team joins on larger builds. WHAT I DO - App rescue for Lovable, Base44, Bolt, Replit, Cursor and Claude Code apps: broken sign-in, Supabase access rules (RLS), roles and data access, Stripe payments, webhooks, emails and failed publishes, fixed in code and tested. - Launch readiness: exposed keys, security headers, access rules, speed and search basics, plus a release checklist before launch. - Migration off Base44 or Lovable to Supabase, AWS or the cloud you choose, with data, users, files and integrations moved and a cutover plan. - Mobile: React Native apps, or your web app prepared for App Store and Google Play review. - Custom web and mobile apps: React, NextJS, React Native, TypeScript, NodeJS, Python, Django, MongoDB, PostgreSQL and Supabase. - AI and automation: AI agents, RAG chatbots on your data, AI voice agents and AI receptionists that answer calls and book appointments, and n8n, Make or GoHighLevel workflows tied to your CRM. RECENT WORK (screens in my portfolio) - AudienceSwop and Passport Photo Now: two Base44 apps moved to AWS, with app fixes and launch support in the same plan. - HealthConnect, Auto Oil & Shine and a trucking management app: Base44 apps audited, repaired and stabilized, from booking recovery and payment gating to roles, dashboards and workflows. - Galaxy Medical Alert: we built the storefront and the staff operations platform on React, NodeJS and MongoDB, both live. One order pipeline with stage checklists, billing from three payment systems in one client file, FedEx tracking, a returns desk, reports and an AI Copilot. We also built AI voice agents for payment reminders and phone orders. - TwinWriter: an AI writing SaaS on Base44 with personas, LLM orchestration, credits and billing. - PropGen AI: my public Base44 template, cloned 77 times by 20 October 2026. In October 2026 my team checked 578 live AI-built apps from public showcases: 9 in 10 sent no Content-Security-Policy. HOW I WORK - A fixed price in writing before work starts, and a written update every week. - You own the code, the accounts and the data. - Softr Professional Certification (May 2026).
