Full-stack developer at Assistea building care-management services and React workflows, with experience running Celetu, a live AI platform.

Message

At Assistea, I work on a care management platform for Italian nursing homes, building FastAPI services with access control, audit logging, and multi-tenant data isolation. I also work on care-records data models and staff workflows in React, and deploy the application with Docker on Linux.

I built and run Celetu, a live AI social lead-generation platform that processes long-running work through queues. In freelance projects, I connected third-party APIs and webhooks, built data imports with mapping and deduplication, and delivered applications from requirements through deployment and production troubleshooting.
