Finalize and Optimize CodeFlow AI

I have an AI-powered site called CodeFlow AI that I built in Google AI Studio, and it is already online in a development state. The core layout, styling, and feature set must stay exactly as they are, but several things still need attention before I can open the doors to the public.

Right now the AI tools are not always returning results, and the contact / submission forms never reach my inbox. Once these two pain points are solved, I also need a full sweep of the codebase to eliminate any other hidden bugs, tighten performance, and make sure every page behaves well on mobile. SEO basics (meta tags, structured data, clean URL structure, etc.) should be put in place during the same pass.

When a visitor launches an AI tool it needs to do one of two things—either generate code or provide programming help, or answer their questions through the chat interface—and it must do so reliably. After you finish, the whole site has to be tested end-to-end and pushed live so anyone can reach it publicly; I will handle the actual domain and hosting, you just hand over the updated source and guide me through the deployment steps if needed. Please do not suggest a rebuild: the goal is refinement, not recreation.

To help me choose quickly, let me know a little about similar full-stack projects you have completed, the tech stacks you prefer for debugging Google AI Studio apps, and your estimated cost and delivery timeline.
