About this gig
Need a web app that actually uses AI, not just talks about it?
I build modern, fast web applications with AI baked in from day one using Next.js, React, and TypeScript.
What I Build:
- SaaS platforms with auth, payments, and dashboards
- AI-powered tools (content generators, analyzers, chatbots)
- Internal business tools with smart automation
- Landing pages that convert with AI features built in
Tech Stack:
Next.js, React, TypeScript, Tailwind CSS, Supabase, Stripe, Claude AI, OpenAI, Vercel
Every Project Includes:
- Clean, documented source code you own 100%
- Responsive design (mobile-first)
- SEO optimization
- Authentication and user management
- Deployment to Vercel or your preferred host
- Performance optimized (95+ Lighthouse score)
My Process:
1. We define your requirements and features
2. I build the app with daily progress updates
3. You review, I refine
4. Deploy and hand over everything
No templates or WordPress. Everything custom-built with modern tech for speed, scalability, and maintainability.
