James Tansley

Software Engineer | Building the AI-led Future

I turn bold ideas into validated, scalable products—fast. From concept to launch, I build what matters.

Building the Future

I'm a software engineer who thrives at the intersection of product and engineering. My specialty? Taking rough ideas and transforming them into market-ready MVPs that attract users and investors alike.

With a bias for action and a deep understanding of startup dynamics, I focus on what truly matters: shipping fast, learning faster, and building products people actually want to use.

I've worked across the full stack, from architecting backend systems that scale to crafting interfaces that convert.
