Vibe Coding Specialist – Lovable & Bolt.new Projects

Freelance

Feb 2026 - Present • 8 mos

Built and fixed multiple AI-generated web apps and SaaS MVPs using Lovable and Bolt.new for startup clients and indie founders. These projects typically started as incomplete or unstable AI-generated applications that looked promising in the editor but failed when real users tried to interact with them. My role involved full debugging of the generated code, identifying broken logic, fixing UI inconsistencies, improving responsive design across mobile and desktop, and cleaning poorly structured AI output so the codebase became maintainable. I integrated Supabase for database, authentication, and real-time features, set up secure user registration and login flows, connected payment systems where required, and deployed the finished applications to Vercel and Netlify with proper environment variables and production configurations. The goal in every case was to take a half-finished vibe coding project and turn it into a stable, production-ready application that clients could actually launch and show to users or investors.

Specialized in taking AI-generated applications from Lovable, Replit, Base44, Bolt.new and Claude Code that were unstable, insecure, or incomplete and turning them into production-ready products. This included fixing critical bugs, resolving authentication and database connection issues, cleaning messy AI-generated code, improving performance, adding missing error handling, implementing proper security practices, and ensuring the application could handle real user traffic. Many clients came with projects that looked good in screenshots but crashed or behaved unpredictably in actual use. My work focused on making these applications reliable, maintainable, and ready for launch so the client could move forward with confidence.
