My name it’s Cris. I am a person with many qualities in handyman.What a handyman means? A handyman, also known as a handyperson or handyworker, is a person skilled at a wide range of repairs, typically around the home. These tasks include trade skills, repair work, maintenance work, are both interior and exterior, and are sometimes described as "side work", "odd jobs" or "fix-up tasks". For me a handyman means the person who helps the people who are in need or not having the necessary training for that thing and at the same time the one who later gives a smile to the people's face.

I was impressed how Amir took the job very quickly - he arrived to work a few hours after seeing the post. He was very friendly and polite and was happy to take the job. However, I really would not recommend him for carpentry work. This was an easy job, where the carpentry was already done and it just needed fitting. He arrived with the wrong tools (had to use mine) and very poorly fitted the cupboards and shelves, to the extent I had to pay another tradesperson to fix the job. The finish was awful.
