Top SchoolAustin Kelleher is a seasoned software engineer and founder with 12 years of experience building scalable web platforms and developer-centric tooling. As a founding engineer at JupiterOne he helped grow the product from zero revenue to eight-figure ARR and contributed to a unicorn valuation, blending product-minded engineering with security and compliance expertise. He now co-leads Opine, applying that experience to streamline technical sales, proof-of-concepts, and post-sales handoffs for engineering-led GTM teams. Austin has deep front-end credentials—maintaining and contributing to high-scale projects like Marko.js at eBay—and a strong background in realtime Node.js services and AWS-powered systems.

Based in North Carolina, he actively shares work on GitHub and favors pragmatic, production-first solutions that scale.
