He is perfect and I am short of words. He is expert in his domain and technical knowledge. Highly reliable too. I would like to again with him infact assigning another project in couple of days.

Unfortunately, the freelancer was unable to complete the project despite me asking him several times to make sure he can 100% do it. I ended up wasting a couple weeks with him. He asked for more money so i ended the conversation quickly and closed the project. He was responsive but that's not good enough. Bad experience here.

I was a senior web/app developer who worked for a big IT company in Antioquia. For some personal reason, I had to move and now I am working as a full-time freelancer.
