About

Tools, teams, and products engineered with care

I'm Valerio — an engineer who finds joy in making machines talk to the cloud. Started with PLCs on factory floors, now I build full-stack products that span from circuit boards to web dashboards.

What drives me? The moment when hardware meets software and everything just clicks. Whether it's a hydraulic arm responding to code or a real-time dashboard streaming sensor data, I live for that connection.

Beyond the code, I bring reliability and structure. Every project gets my full attention — from understanding the real problem to delivering a solution that actually works in production.

Full-Stack Reality

Not just web full-stack. I mean PCB design to cloud deployment — the actual full stack that makes products work.

Battle-Tested Code

My code runs on construction sites and factory floors. When failure means a stopped production line, you learn to build differently.

Product Mindset

I don't just write code. I understand business needs, user workflows, and what it takes to ship something people actually want to use.
