Rockstar🎓
Top SchoolGrzegorz Stepniewski is a software engineer and technology leader based in Krakow, currently working on Google's Web Apps team while co-leading product and tech strategy as CTO of SmartDust. He brings a practical blend of mobile and embedded systems expertise from roles at Samsung, multiple Android developer positions, and a tech lead stint at HSBC. With a background as an assistant lecturer and years mentoring teams at Avanade, he pairs hands-on development with teaching and process leadership. His trajectory shows a knack for transitioning between startup and enterprise environments, shipping client-facing Android products and platform tooling. Though early in his official "years of experience" count at Google, his decade-plus technical career includes system-level C/C++ work, Java/Android engineering, and cross-disciplinary roles like Scrum Master and trainer. He combines curiosity about platform internals with a founder’s sense for product delivery.
