Fix Overnight Shipping Checkout bugs Damian did a string of jobs for me initially, and has completed another series of projects on the website. All have been done efficiently and effectively. Will definitely be returning to his expertise when needed.

Copy website to a new domain and create automation for validating payments We had some communication roadbumps, which happens on complex projects. However we worked it out, and the job got done. Our website setup is pretty novel and extremely unique and Damian got it done and had creative solutions in order to get what we wanted functioning. I find myself coming back to him for repeated jobs that others cannot seem to comprehend or do properly because he is reliable and knows these systems more in depth than your average cheaper and lower caliber developer. Of course it is attractive paying a fraction of the cost for other developers, and in some instances that is all you need- but if you want something done clean, correctly, and thoroughly just hire Damian.
