I will create ai website using fastapi and postgresql


About this gig
You have an idea. I will build it into a web application that people can actually use.
Most developers just write code. I build systems that can handle real users survive traffic spikes and do not break when they are in production.
I am a backend engineer who specializes in building AI-powered web applications using FastAPI, PostgreSQL and LLM APIs like Groq, OpenAI and Gemini. I do not just add an API key to my projects. I design the caching authentication, asynchronous task layers and deployment pipelines that make AI applications reliable.
What I have built:
* StudyMindAI is a -user AI study assistant that I built with Flask, PostgreSQL, Redis and Groq. It uses SHA-256 content hashing for fast repeat queries, JWT authentication, Docker and it is deployed on Render with a cache layer that isolates users so no one ever sees another users data.
* NGO Connect is a platform that connects NGOs, donors and volunteers built with Flask, PostgreSQL, Redis, Celery and Razorpay. It has OTP registration, JWT authentication, donation and volunteer flows asynchronous task queues and it is deployed on Render with real payments and real users.

FAQ
Do you provide the LLM API key?
No — you bring your own API key (Groq free tier works great for most projects).
Will the app be deployed live?
Yes, on Render or Railway (free tier). Custom domains available on request.
Can you add a frontend?
Yes — basic chat UI, dashboard, or landing page can be added. Mention it before ordering.
What if I need changes after delivery?
Revisions are included as per the package. I don't disappear after delivery.
