Went unresponsive for months at a time and eventually stopped responding. Never met promised deadlines, and the "final" deliveries did not accomplish what he was hired to do. He ended up being a huge waste of time and money, resulting in us having to pay a 2nd engineer to start over on the project. We've worked with several freelancers over the years, and the rest have been great. Adip was highly disappointing.
