Stripe payment flows for mobile and web
Usman and his team have been amazing to work with. Their knowledge of the Stripe platform got us up and running quickly. They have great attitudes and were very flexible on meeting times. The code was solid, well-documented, and reviewed together so the hand-off went smoothly. We are now running the Stripe implementation they built for us in production. They even did an audit of our overall codebase to make sure we were not going to run into any snags. I highly recommend Usman and his team!

Advise on AI Generated MVP App
Usman clearly explained his process to complete the short project before we began. He completed the work and provided code review guidance and recommendations as discussed. I would use him again when ready.
