Jeff Bellsey is a seasoned software engineer and former CTO with 12+ years of professional experience building user-centered web and mobile applications from San Rafael, California. He specializes in modern JavaScript and front-end architecture, having led public-facing web apps and internal tooling at Lookout and currently contributing to Benchling’s engineering efforts. Jeff has run his own consultancy, Future Ground, delivering custom React/Angular apps, mobile builds, and product launches, and previously oversaw large-scale e-learning infrastructure and multi-six-figure product rollouts as CTO. Comfortable across the stack, he blends hands-on coding, UX-driven component design, and team leadership—skills honed from early C++ application architecture at TreeAge through decades of mentoring and training. A detail not obvious from titles: he pairs product-facing design sensibilities with deep operational experience (devops, data integrations, documentation), making him effective at translating executive priorities into reliable, maintainable systems.
