Senior🎓
Top SchoolJon Hollingsworth is a Lead Software Engineer with 11 years of professional experience building and delivering web-based software and leading engineering teams across New Zealand and internationally. He combines hands-on full-stack development (Django/Python, React, Ember, Postgres) with program-level delivery experience from roles including Director of Engineering and project leadership at enterprises like Barclaycard. Jon has repeatedly moved between hands-on coding and engineering management, shipping complex integrations and large multi-stakeholder projects while maintaining technical ownership. His background in AI and mathematics (BSc Hons) gives him a methodical, data-informed approach to problem solving, and he has operated across startups and corporate environments—from feature-level development to multi-million-pound program management. Currently leading engineering at Cogent.co and with experience at CashApp (Block) on his GitHub bio, he brings pragmatic delivery focus paired with a habit of translating vague requirements into clear, auditable solutions.
