    Finland - Last active: 1 day ago - Tests: 8 - Portfolio: 5

    Over 6 years of experience of Magento development, I am a high ranking Magento expert and have so many experience of Magento. I am highly experienced with both back-end and front-end development including but not limited to Apache, MySQL, PHP, HTML, CSS, JavaScript, and jQuery. I am a solo developer working alone which allows me to complete projects more quickly and efficiently than needing to incur the overhead of team communication and scheduling. I find, develop, and implement solutions even when others have deemed the "problem" impossible. Though I work quickly, it is never at the expense of correctness or security of the solutions. My Goal is gain credit with All PEOPLE.

    United States - Last active: 1 day ago - Portfolio: 27

    Hey there! I am Destini, also known as visual.destini online. I am a freelance graphic designer with a background in traditional art and photography, residing in Central PA. My life-long love affair with design flourished with an arts-rich education, leading me to pursue my Graphic Design degree from Art Institute of Pittsburgh. After finding a lack of inspiring design work in my area, I decided to take a leap. I left my day job and my visual.destini brand was born. I anticipated the hard work and long hours- but not that my love of design would grow so drastically.
