    “Diligent worker. But final solution used a GPL-licenesd library which I explicitly requested not to be used in the project requirements. After finding the GPL code (I was also not notified of it), I had the option to pay extra for a different solution. But that would have pushed it out of budget. I also had to waste my own time getting the solution to work on my machine, due to all dependencies not being included. Dr. Lu seems good for certain type of projects. He definitely is familiar with audio technologies. But I'd be very hesitant to hire again, especially for any projects which might have commercial basis.”
