About Jack

Hello, I’m Jack, a technical leader, product engineer, and problem-solver with deep expertise in full-stack development and artificial intelligence. I’m passionate about turning complex problems into simple, impactful solutions that people genuinely love. Joyful tech.

Over the past decade, I’ve moved fluidly between engineering, product, and AI, designing systems that make technology feel more human and interactive. Over the last 5 years, that meant working with generative models and structured conversation frameworks, tools that help people explore and understand data intuitively. From trading Co-pilot, which turns trade intelligence into dialogue, to Mass, a platform that simulates diverse human feedback at scale, I build products that don’t just automate, they listen, learn, and respond.

I’ve had the privilege of collaborating with some of the best teams in technology, such as Kpler, Google (YouTube), Whereby, IBM, Air New Zealand, News UK, Tesco, and a roster of international agencies, building everything from scalable multi-platform applications to bespoke CMS platforms, e-commerce ecosystems, and sleek mobile apps. My now bridges product, engineering, and insight, transforming complex datasets into tools for decision-making across finance, maritime intelligence, and consumer research.

Beyond the code, I thrive as an interdisciplinary connector, leading and supporting diverse teams, bridging the gap between business and engineering, and championing new technologies that make a difference. My approach is simple: cut through the noise, simplify the complex, and create systems that work beautifully. At its best, technology isn’t just functional, it’s joyful, human, and quietly transformative.
