Full-stack Developer for Web Application (React, Node.js, PostgreSQL) - API Integration Expert
Nazmul has been prompt in responses. He understands the requirement well and was able to work independently after giving instructions. There were few open questions that I had but he was able to ensure that the ask is clearly documented through our interaction. This kept the communication and work expectations clear from the start. Will definitely consider him again in future as we have increased work load.

Frontend web development of bitsimplify.com
Nazmul worked on improving the frontend of bitsimplify.com. He finished the project ahead of time and I'm quite happy with his work. Nazmul suggested a better library from react than i was initially looking at. The different windows are now responsive as well as resizeable!

Frontend development of jaiganpati.com
He designed the frontend from scratch with a nice UI using the MERN stack. I'm super happy with his work and already hired him for the next work. He listened to the details and provided valuable insights into the direction I'd like to take. His design and coding ability are mature so it was easy to understand the code he wrote. I'd recommend Nazmul to anyone looking for developing website using the MERN stack.
