As a freelance AI and full-stack developer, I build, improve, debug, and deploy modern web applications using Lovable AI, Base44, Replit, Vibe Coding, Cursor, Claude Code, and other AI development tools. I specialize in turning ideas into functional SaaS MVPs, business websites, dashboards, internal tools, and scalable web applications. My experience includes Lovable app development, Base44 development, Replit development, Supabase integration, API integration, Stripe payments, authentication, databases, AI features, and third-party integrations. I also help clients fix bugs and errors in AI-generated applications, debug existing codebases, improve application functionality, and prepare projects for production deployment. I work with clients on website and application migrations, including Lovable to WordPress, Base44 to WordPress, Replit to WordPress, Wix to WordPress, and other platform conversions. I also provide website cloning, redesign, customization, mobile responsiveness, performance improvements, and ongoing technical support. My focus is on building reliable, production-ready applications rather than simple prototypes, while helping clients turn AI-generated ideas and existing projects into working products.
