About Johannes
Fast Web App Developer | HTML, CSS, JavaScript & AI-Powered Tools
Bad Muenstereifel, Germany - 1:17 am local time
I build clean and responsive websites, landing pages, dashboards and custom tools using HTML, CSS, JavaScript, Next.js and various AI APIs.
My focus is on creating lightweight solutions that solve real problems quickly:
- AI-enhanced features (text generation, analysis, automation)
- Responsive UI/UX for desktop and mobile
- Custom dashboards and admin panels
- Automation tools for businesses
- Small MVPs, prototypes and micro-SaaS
- API integrations (Supabase, Stripe, AI models)
I use AI to speed up development, improve product quality and deliver working results in short timeframes.
If you need a clear, functional and modern solution — I can build it efficiently and reliably.
