Ameer Haider
About this gig
Most AI SaaS ideas stall at the same place. The concept is clear, but turning it into a working product with real OpenAI integration takes an engineering stack most founders don't have in house.
WHAT I BUILD
Custom AI SaaS web apps powered by the OpenAI API. Full stack work covering the frontend, backend, database, authentication, and the AI layer that makes the product worth paying for.
WHERE I FIT
Already have a product and want AI features added? Start with Basic.
Have an idea and need a working MVP to show users or investors? Standard.
Ready to launch with billing, RAG, and full deployment? Premium.
THE STACK
React, Next.js, Node.js, Python, PostgreSQL, OpenAI API, RAG pipelines, vector databases, Stripe, AWS and Vercel deployment.
HOW IT WORKS
You send your feature list and timeline. I confirm scope and what's realistic in the budget before anything starts. No surprises mid build.
WHY ME
I'm part of an established software team, not a solo freelancer juggling five gigs. That means real delivery capacity and code you can hand to another developer later without apologising for it.
Message me with your idea and I'll tell you honestly what it ta

My Portfolio
FAQ
I have an idea but no technical spec. Can you still work with me?
Yes. Send me what the product should do and who it's for, and I'll turn that into a clear feature list with a realistic timeline before you order. Most of my clients start exactly here.
Do I own the code and the OpenAI account?
You own all source code fully once the project is delivered. The OpenAI API key stays on your own account, so you control billing, usage, and access from day one. I never hold your credentials.
What are the ongoing costs after delivery?
OpenAI API usage and hosting are billed directly to you and depend on traffic. I'll give you a realistic monthly estimate during scoping so there are no surprises after launch.
Can you add AI to my existing app instead of building from scratch?
Yes, that's the Basic package. Send me your repo or stack details and I'll confirm what's possible before you order. Works with most modern frameworks.
What if my project needs more than the package covers?
We settle scope in chat before you order, so the package always matches the work. Anything extra is quoted as a clear add-on rather than discovered halfway through the build.
