About

Profile

I lead engineering organizations that ship mission-critical products at scale. Currently an angel investor in small, early-stage projects, backing founders and hands-on building with them — with a strong focus on AI, automation, and platform-scale products.

Previously a Senior Software Engineering Manager at Rapid7, driving Threat Intelligence platforms with agentic AI and automation, and VP of R&D at Blings.io, where I owned technical strategy and scaled the product from early stage to enterprise-grade maturity.

I care about strong engineering culture, pragmatic architecture, and growing the people I work with.
