About this gig

Need an AI chatbot that actually feels humanand drives business value? I build GPT-powered agents with dynamic personalities, memory, and production-ready architecture.


I created MentorProfit (mentorprofit.com), a platform with 4 specialized AI finance mentors, each with custom system prompts stored in MongoDB, rate limiting, and AdSense monetization.


What you get:

GPT-4o-mini integration with dynamic prompts from DB

Conversation history + user memory (MongoDB/Firebase)

Custom chat UI (React + Tailwind + Framer Motion)

Rate limiting + abuse protection

Admin panel to edit prompts without redeploying

Optional: RAG pipeline, vector search, analytics dashboard


Perfect for consultancies, edtechs, fintechs, or creators who want a differentiated AI experiencenot just another wrapper.


Bonus: I optimize for cost efficiency (token management, caching) so your bot stays profitable.


Let's design your AI agent. Message me with your use case!
