I can handle the full development process, including responsive frontend, backend APIs, database setup, authentication, user roles, dashboards, Stripe payments, third-party integrations, testing, and deployment.
With 6+ years of full-stack experience and $70K+ earned on Upwork, I have worked on SaaS platforms from initial concept through production, including React rebuilds, Next.js applications, Firebase systems, and OpenAI-powered products.

I had an excellent experience with Saadee as a service provider. He seamlessly became a very high contributing member of our team. I was very pleased with his productivity and level of communication.
I would not hesitate to hire Saadee again as a developer.
Additionally, Saadee could easily move from our mobile app team to complete tasks and go back to our web application team so his versatility was very helpful to us and made him more valuable.
Lastly, Saadee has integrity and you are rolling the dice in hiring a developer and he totally took the risk out of the equation. Hire him!

Platform - V1 Front-End
Saad took our platform from 0 to 1 - completely rebuild our front end to an AMAZING UI & UX.
He doesn't just check boxes, he brings a masterful strategic approach and if wanted will bring amazing ideas on how to make your platform way better than what you're thinking.
Never ever missed a deadline. I will absolutely be working with Saad on any front-end/back-end related things in the future.
