You will get custom AI-powered web app built with GPT-4
Project details
You need AI in your product but don't want to spend weeks figuring out the integration. I'll handle it — cleanly, fast, and production-ready.
I've built AI-powered SaaS platforms, GPT-4 content tools, and custom chatbots for real clients. I know how to wire OpenAI, LangChain, and Hugging Face into web apps that actually work in production — not just demos.
What I deliver:
GPT-4 / OpenAI API integration into your existing or new app
Custom AI chatbot, content generator, or automation workflow
Prompt engineering tailored to your specific use case
Clean Next.js + Node.js code — maintainable and scalable
Deployed and ready to use
Whether you need a simple API hookup or a full AI-powered SaaS with auth, billing, and dashboard — pick the tier that fits and let's get started.
Message me first if you're unsure which package fits your project. I'll point you in the right direction within a few hours.

Webflow Website Development for a DEX (Wrap)
Requirements from my hand were clear (Figma + Webflow), he did deliver the first milestone (Figma), I paid.
After he kept in DMs proposing to change from Webflow to NextJs (because he was not able to deliver it).
I told him to stick with requirements but in the end the quality of the product was very low, and there is no animation and the website looks very bad.
He then proposed again to rebuild the website in NextJs against my will, hence I decided to close the contract.
I have now to hire a new developer for the second milestone: the Webflow website.
