It has been 14 years since I started here in oDesk, which is now Upwork. I have acquired the necessary experience needed in the online market and business ventures. I have improved my 5 work policy ever since I started in this line of work. These would be: 1) To always ensure the Client gets quality work. 2) To always submit the Client's work on or before the deadline. 3) To always have a stable and open connection with the Client. 4) To always inform the Client of any emergencies or problems with the work several days prior to the deadline so as not to hinder the progress. 5) To always ask questions as long as it is necessary pertaining to the Client's work. My record and rating may not be a 5-star brand, but the quality of the work I put out is always good and near perfection. I hope that anyone who is interested in hiring me sometime in the future will get what they really want and how they want it.
