Rosario Colletti

I've spent 20+ years designing and operating production systems across five countries, including distributed data pipelines at Opera Software and the OpenAir SaaS platform at NetSuite.

At NetSuite, I modernized a mature Perl monolith competing with Salesforce, introducing cleaner class-based components, a modern JavaScript UI, and backend and database improvements for long-term maintainability. At Opera Software, I built and maintained a data warehouse framework processing hundreds of GB of logs daily through distributed file systems and map/reduce technologies.

I've also led backend and technical strategy as CTO at Crowdholding, deploying Ethereum smart contracts and delivering a collaborative marketing platform. Across multiple ventures, I’ve remained hands-on with full-stack development, infrastructure, IT operations, IoT services, Docker, analytics, and production performance work.

I'm rebuilding my hands-on stack around Go and AI-assisted engineering tools, using them to accelerate delivery while keeping architectural judgment at the center. I bring autonomy in ambiguous problems, practical legacy-modernization experience, and business ownership experience from founding and running a hospitality business.
