High Performance Perl MTA Programmer

“This was a difficult job involving things alexey was unfamiliar with. He was able to get 75% of the way there but couldn't close the gap in the timeframe i needed. I think alexey is probably a good programmer for most tasks, it just wasn't working out with this one. This was a learning experience for me as the first time using a contractor in a situation like this. Rather pay per milestone, i agreed to pay hourly, and I did not try to negotiate down the rate requested. I also agreed to allow the hours to be kept track of manually outside of the odesk tools. Alexey is very confident and had positive feedback so i decided to essentially trust him and his abilities until proven otherwise. Alexey initially said he would deliver the feature request the next day, this repeated 14 days in a row until i was hit with a $1300 bill for a single undelivered feature. I would have never agreed to this 1 feature taking 43 hours to complete in advance, it is a massive overbilling. His perspective is that he already put the time in, so even if it wasn't delivered, i'm paying for his time not the feature, despite the fact that he failed to deliver it in the time frame he specified repeatedly. The amount of time the feature is taking, the cost, and alexeys somewhat abrasive demeanor just aren't working out for me.Positive feedback i would give for improvement would be to have some humility & humbleness, alexeys favorite response is "yes i already knew this" , including to things it is impossible he could know. Overall I did like alexey and think it could have worked out well on another project, I wouldn't say I don't recommend him, but I am not happy with the progress of this experiment and thus am concluding it.”
