At Viewled S.A., I develop Veerlow, a Digital Signage SaaS platform for managing and distributing content and remotely monitoring commercial screens. My work includes its multi-tenant backend with FastAPI and PostgreSQL, web CMS with React, and real-time device communication with WebSockets.

I also develop players for Android, Samsung Tizen, and LG webOS, and interactive experiences using Flutter and computer vision. Previously, at CodeLab SpA, I developed RPA automations with NestJS and Puppeteer and integrated external financial and human resources APIs.
