Summary
👤
Senior🎓
Top SchoolJon Hewines is a product-minded technology leader and co-founder who helps founders and leadership teams modernise complex, business-critical software and turn unclear goals into products that work for users and the business. With 20+ years of experience spanning product strategy, UX, architecture and hands-on engineering, he specialises in guiding small, capable teams through high-risk, high-impact transformations without resorting to risky rewrites. As a fractional CTO and delivery lead he embeds with CEOs and product teams to align strategy, prioritise outcomes and establish pragmatic delivery, testing and release practices that drive measurable commercial recovery. He has led large legacy modernisations—rescuing a ~1M LOC platform to restored customer trust, recovered sales and an industry award—while experimenting with AI-assisted development workflows in real product environments. Jon prefers long-running engagements where trust and continuity matter, balancing pace, quality and real-world constraints rather than chasing technology for its own sake. Based in Waverley, England, his unusual background in mathematics, psychology and acting informs a pragmatic, user-focused approach to technical leadership and stakeholder communication.
