I have had the pleasure of working with Nabin for about 6 months on Cirun.io. We hired him for his ability to quickly learn new stuff and I am glad to say that he didn't let us down. He was very proactive and picked up our stack fairly quickly and we had an extremely productive 6 months with him. He contributed to various crucial features of Cirun and also wrote very descriptive documentation and blog. He is definitely a very valuable asset for any engineering team. I highly recommend him for his excellent technical skills and communication.
