Hire the Best VOIP Administrators
in the Philippines

Hello, I'm Alberto Jr Pontillas. I hold a Bachelor's Degree in COMPUTER SCIENCE. My primary strengths lie in my quick learning ability and my aptitude for adapting swiftly to changes. One of my most notable achievements was being recognized as the top performer for two consecutive quarters, leading to my promotion twice within a span of 6 months. I firmly believe that Integrity is essential in the workplace. Without it, building relationships becomes challenging, leading to unclear communication and hindering business growth. Two of my key strengths include my receptiveness to feedback, which I see as an opportunity for improvement and growth, and my consistently open-minded approach. Outside of work, I dedicate my spare time to playing basketball to enhance my physical fitness, and I enjoy watching English movies or anime with English subtitles. Thank you for considering my profile. I'm eager to contribute to the growth of your business. Have a wonderful day!
