Full Stack AI SaaS Developer (FastAPI + React + OpenAI) – MVP Task
Working with Asad was a great experience. He has strong full-stack knowledge and clearly understands both backend and frontend development very well. He handled the FastAPI, OpenAI, and React integration smoothly, delivered clean and well-structured code, and was able to solve issues quickly without much guidance. Communication was clear, deadlines were met, and his overall technical understanding made the process easy and efficient. I’d definitely recommend him to anyone looking for a reliable full-stack developer, especially for AI SaaS and automation projects.

Find Stripe expert (payment-intent) related
He did get the job done, so good job overall. However, from a communication point of view, I had agreed that the payment could increase for teaching and coding work, but there was an issue where he did extra work outside the agreed scope without getting approval from me first. I don’t think he did that intentionally, but if you work with him, make sure the contract clearly includes all important terms before starting. In the end, we resolved the problem peacefully, but I had to pay extra.
