This has been an absolute nightmare woking with Salik. I wish I could rate him lower than one star for each category. The work was basically copy-pasted from various sources from the internet along with poor written quality (grammatical errors/poor english). There was an absolute lack of professionalism. He rushed me into releasing him the milestone and since I was new to this platform, I quickly did it before completely proofreading the work - please beware. Low to no expertise when it comes to financial research, economics or mathematical problems. I would not recommend him to anyone and would definitely not be hiring him again.
