Jacqueline McAndrew (HomeSav)

Content Strategist at Facebook

John was senior to Jacqueline but didn’t manage directly
John is a highly skilled developer who is passionate about his work and about the success of the companies he's worked with. His drive, commitment, and responsibility make him a valuable team member, and his clear-headed, organized, and efficient problem-solving abilities and leadership skills make him an ideal development manager. 

As a marketing professional, I appreciate the rare combination of finely-honed technical expertise with marketplace knowledge and insights. John embodies both of these qualities. As the CTO of HomeSav, John was tasked with some unique challenges: prepping our servers for ever-increasing volumes of traffic, an easy-to-use backend capable of handling a huge number of products and vendors, intelligent and informed on-page tracking to provide customer insights, and bespoke features and applications on an innovative e-commerce platform. John rose to the occasion time and again, and we were left with a clean, appealing, and lightning-fast website that was tailored to our needs and provided value both to HomeSav and to its customers. As the social media marketing manager, John's knowledge and enthusiastic approach towards marketing efforts was refreshing and invaluable.

John is a true and exceptional talent. I'm incredibly thankful for the time we got to spend together as co-workers - it was educational and inspirational. I would consider myself lucky for the opportunity to work with John again, and I enthusiastically recommend him to any company that is fortunate enough to work with him in the future.
