À propos de moi
Hi, I’m Sienna. AI builders like Lovable.dev are great for fast frontends, but they often break when handling complex databases, API connections, or user security. That’s where I step in. I fix your broken Supabase backends, configure secure Row Level Security (RLS) policies, and connect custom APIs or n8n automations. Based in Australia, I help founders and SMEs turn glitchy AI prototypes into stable, production ready SaaS MVPs. Stop wrestling with AI errors. Let’s make your application secure, functional, and ready for real users. Message me with your project goals today!... Plus d’infos

Architect and deliver high-performance web applications and SaaS MVPs utilizing advanced AI-assisted development (vibe coding), modern front-end frameworks, and secure relational database backends.
