The last three years I have worked closely with Samarth to develop and maintain a communication and teaching app. He has outstanding developer skills - fast, organized, reliable, positive and competent and smart. He is always responding immediately and his fluent English makes communication easy.
I have worked with quite a few local and remote web developers. I am yet to find anyone with the level of talent, professionalism and project commitment that Samarth has. Real pleasure to work with him, hope to do more projects together soon!
After more than one year of being guided by Samarth Agarwal into the tech world, my coding skills and my attitude about mobile development have shifted 180 degrees. Now my programming appetite is increased and I feel confident coding.
