articles for humans. He’s worked as an agile coach, Linux System Administration. He has been actively using
a developer, and a garage attendant, but not in that Python since 2001. He has been a developer, system
order. He can write code in over 10 languages and administrator, quality assurance engineer, and tech
prose in just one, and when not writing, coding, or support analyst. They all have their rewards and
coaching, he spends much of his spare time traveling challenges, but his most challenging and rewarding job
