You will get an AI Integration and OpenAI API Setup for your React Web App
Project details
Looking to add powerful AI capabilities to your platform? I build secure backend endpoints and interactive React frontends integrated seamlessly with OpenAI, Claude, and custom AI agents.
What I offer:
• Custom AI Features: Connect OpenAI API keys to your input components with clean UI states.
• AI Chatbots: Build interactive chat UIs featuring real-time data streaming and context memory.
• Full Stack AI Dashboards: Integrate advanced Vector Databases (Pinecone/Supabase) for RAG systems.
As a specialized Full Stack React developer, I ensure your API tokens remain hidden and secure on the backend, while your frontend remains fast, responsive, and easy to scale.
Note: You must provide your own API keys. Complex custom UI designs outside the agreed scope can be handled via custom offers.

Ongoing Design and Layout work
I found that the timezone difference was a problem so no one's fault really. I just had to wait until the afternoon to respond to issues that I should be responding to in the mornings. We did a great job initially on the designs and then someone wanted to change them all and it was better to start with someone fresh and accept that this work though nice was no longer useable. We, therefore, needed fresh eyes and enthusiasm for the rebuild.

Continue UI/UX Design of Sustainable Marketplace
Diana came in to complete unfinished design work which wasn't her doing. This is usually a difficult task. She did it with ease, understood what we needed to do, and executed well. I will continue to work with her in the future, for sure!
