Endorsements from past clients

"Usama was the first engineer to work on our React Native mobile app. He designed the initial architecture and developed the mobile app to meet our business goals in an extremely short period of time. Throughout the project, Usama was productive, professional and proactive to make important product recommendations or share his concerns in a respectful and direct way which helped the team move faster. He was also easy to communicate with and responsive. Usama is a solid team player: he helped others, asked for help when needed, and put the project first."

"I originally hired Usama to support the validation of some react native coding that was completed by an unqualified developer based in Romania. Usama was quick, reliable and professional feedback during the validation process. As such, it had only made sense rehire Usama to build my companies application @usmbl. Usama is trust worthy, knowledgeable, fast learner, winning attitude and keen to make sure my business is a success. I highly recommend Usama to take your business, goals or dreams to the next level!"
