Marco Bellinaso

Engineering Lead, Principal Architect, Head of Tech

I’m a passionate and driven engineering leader with over 20 years of experience across companies of all sizes—from startups (I co-founded and served as CTO of one), to large public companies. Throughout my career, I've built and scaled high-performing teams, driven major product initiatives, and led impactful engineering projects across e-commerce, mobile, and backend systems. Notably, at ASOS.com (UK's most popular fashion online-retailer), I helped build a mobile team from scratch, scaling it to 50 members and introducing data-driven strategies that optimized operational efficiency and elevated the user experience. I’ve been working remotely for much of my career and have developed a knack for effective collaboration, clear communication, and maintaining accountability across distributed teams. I take pride in fostering a culture of growth and continuous improvement, mentoring engineers at all levels, and setting high standards for technical excellence. With a background spanning mobile, web, and backend development, I thrive in architecting complex systems, ensuring product quality, and taking full ownership of the projects I lead. I’m fueled by a commitment to delivering value, creating positive outcomes, and driving innovation at scale.
