I build and scale secure enterprise B2B SaaS and AI/data products as a fractional CTO.
ItalyWhat I'm looking for
I've co-founded Iterpro and owned its end-to-end technical strategy for a decade, building an enterprise B2B SaaS platform for sports performance and injury-risk analytics. The product scaled to 200+ enterprise clients and 5,000 users, culminating in a successful acquisition in 2025.
I've built and led a cross-functional engineering team of 5–10 people, owning architecture across the MEAN stack, TypeScript, Azure, and AWS. I also directed AI-driven enterprise integrations, including read-only Open API data pipelines that enable clients to build AI models on core platform data.
Retained as CTO following the acquisition, I'm leading ISO/IEC 27001 certification through ISMS design, risk assessment, and audit readiness. I now offer 1–2 days per week as a Fractional CTO and Technical Advisor for startups, scaleups, and SMBs needing senior technical leadership.
