John Goodwin was born in 1979 on South Korean soil as an American citizen to US Army parents. He moved a lot with his family, eventually spending much of his youth in Washington State.
After meeting his wife Jane, he moved to California, where he soon became employed as a professional software developer for a company in Canoga Park, CA, known as Cyberspace Headquarters, LLC. While working there for several years, he progressed from the the new guy to Lead Software Developer, in charge of two or sometimes three other software developers as well as off-shore development projects. The economic downturn of IT companies post 9/11 eventually took its toll, and he moved with his wife further out of the city to look elsewhere for employment.
Next, he took up some teaching opportunities in the rural northern Los Angeles County, and was also a short-term employee at a Simi Valley factory, looking to improve worker efficiencies. Soon, he heard of an opening in the city of Los Angeles as a contract software developer; he was interviewed and started work.
During the housing boom from 2002 to 2006, it was very clear that Southern California's bubble was about to burst. He and his wife sold their home in favor of moving to Lake Royale, where he continued to work for the City of Los Angeles by telecommuting.
After working for seven years for the City of Los Angeles, he started working at CareAnyware, developing healthcare related software for home health and hospice.
CareAnyware was soon after purchased by Brightree, where he continues to work, writing post-acute healthcare software with a great team.
His passion for bringing technology to bear on creating value in the lives of others is mysteriously tolerated by his loving wife.
Unable to find a normal way to work out and keep fit, he participates in local sprint triathlons (and maybe he will participate in a half triathlon in 2014), which motivates his workout schedule.
His brother, mother, and stepfather all contribute to his family support structure.
