eReader Application Developer“Roman is an outstanding developer and a valuable, cooperative team member. He is very professional, efficient, trustworthy and reliable. We will definitely use him again.”
Sr. Ruby on Rails Developer“I have now completed two separate contracts with Roman, and he consistently exceeded my expectations and those of upper management, whom I included in meetings with Roman on several occasions. I have managed several dozens of consultants over the course of the past 15 years and I can honestly say that Roman ranks at the very top of my list. To complement his terrific technical (both architectural and development) skills, his command of the English language is better than most Americans, as he has used the English language for his entire life in addition to his native language. He is both a team player and an independent thinker. I look forward to hopefully working with him on future projects. Just super.”
Back-end Ruby on Rails Developer“He wasn't available enough for my needs.”
Modify Python Script“Excellent work. He went above and beyond what I asked and did it faster than promised.”
Scraping / Optimization Program“Fantastic Rails programmer. Am using on a follow on project currently.”
Create Interface to integrate Python module with Ruby website“I was very happy with Roman's work. He was quick to respond and performed high caliber work. The deliverable was exactly what I expected. I would have given him 5 stars, but the communication at the end became a bit difficult as he had email account troubles.”
