My name is Sinisa Petkovic, and I am a software developer with over 20 years of experience in writing and actually shipping software with a variety of teams in a variety of environments from 2-person startups to enterprises with more than 500 developers. I have tinkered with computers and software since I got a Commodore 64 back in the early ‘80s and PC XT shortly after. In recent years, I immersed myself in full-stack web development, single-page web applications, responsive web design and web performance optimization. ©
