He is a very sharp engineer to solve the product issue immediately.
We used to flow Agile project management but there was lots of change request every time in every sprint but he is handling all the request very smartly. In the end, I saw him not only software engineer but also have a mindset of product life cycle logic and business.

Very much a can do attitude. Just need to keep on top of the delays due to Covid etc. Communication on milestones and delays could be improved whenever there is delays. Silence is best resolved with regular updates to your employer

Ruhul has a positive 'can do' attitude which enabled both himself and I to learn and develop. Ruhul was always keen to complete the projects I gave him. Ruhul was committed to ensuring I was satisfied with the work. Even when I myself had no experience designing websites or actually being fully clear on my needs, Ruhul was always enthusiastic and maintained I had no worries. He delivered above my expectations every time. I will continue to maintain Ruhul as on ongoing "support" for my website as I am sure that he will be dedicated and reliable.
