React Front-End Developer Needed to Build Responsive Web App & Landing Page from Figma Designs
I have used several front end developers in the past, Kousik was by far the best one. He understood the project requirements immediately and provided high quality work that far exceeded my expectations. He was always available, very easy to communicate with and went above and beyond with his work and deliveries. I felt like he was truly a team player who cared about the product as much as I do and that's something that's not easy to find.
Overall I highly recommend him for anyone who is looking for front end/full stack developer and I am sure I will hire him again in the future.
