Abraham Petrillo is a seasoned technology leader and hands-on engineer with 14 years of experience building full-stack web applications and leading engineering teams. Currently CTO at FINSYNC after progressing through VP and Director roles there, he blends strategic leadership with deep practical expertise in Ruby on Rails backends and Ember front-ends. His background spans server and ops work—databases, Apache/Phusion Passenger tuning—and app development in PHP (Yii, CakePHP) and Ruby (Rails, Sinatra), giving him rare cross-stack fluency. He has a track record of scaling products and teams in both startup and enterprise environments, and founded an early consultancy (Mr Techie) that demonstrates his entrepreneurial bent. Based in the United States and educated in computer systems at the University of Limerick, he often pairs UX-focused implementation with robust backend engineering—an approach honed during early Rails UX work at Sage.
