    Pakistan - Last active: 5 days ago - Tests: 2 - Portfolio: 9

    Ali is what I call a Soup-to-nuts developer. He can take a design concept and complete it from the beginning to end. He has a strong sense for the visual user experience and his Mobile Application work is high in quality. There is a worldwide maxim “Those who can’t do, teach” that stands true for many. But I believe that “Those who have done, mentor”. Ali Raza is certainly a member of the latter group! - Curtis Fisher - CEO PowerSource Industries I've known Ali Raza for more than 3 years he was my editor/reviewer and he helped me a lot when we worked on FFD magazine. He is very professional and thorough with everything he does. He's very friendly and he always put passion in the work he did. I can always count on him. - Ewa Dudzic - Managing Director/Editor at H9Media Ali and I worked together on building https://5amily.com/. Ali was sole flex developer that looked after building our flex client. Integrating API generated by our Rails backend in the client. We were in a hurry when we started porting our HTML/Javascript client to completely flex. And needless to say it was pleasant working with him in tight schedule. A schedule where requirements were constantly changing. He knows his craft very well and is also passionate about learning everything that is new out there. I will highly recommend him to anyone. - Waseem Ahmad - CTO at Authorly, Rails Contributor I am a lead designer, developer, author, consultant and entrepreneur with over 8 years of global IT industry experience in almost every field of design and development. I am not only a Jane of all trades, but I've also mastered many disciplines. I started my career in 2002 (yes when I was in 9th grade) from graphic designer to web design and later development during my studies in computer science. Currently I am passionate about developing applications and games for multiple platforms using cross platform technologies. I hold a Masters degree in computer science in addition to over 100+ official certifications in the field of design & development from Adobe, Microsoft, Oracle and Zend. I happen to be not just Pakistan’s only Adobe Training Partner but also Pakistan’s only Microsoft Certified Trainer in Enterprise, Desktop and Web Development. I am a published author and have written exam guides for Adobe Flex. Furthermore, I have also contributed to several articles in Flash & Flex Developer Magazines.
