YSMART develops monitoring and decision-support solutions for digital power substations in the Brazilian electrical sector. I joined the company as an intern in 2023 and became a mid-level front-end developer, working there until 2026.

My main work was on n-Watch, a desktop and web application for monitoring IEDs (Intelligent Electronic Devices) on IEC 61850 networks in electrical substations. n-Watch was deployed at the Lorena Substation of ISA Energia Brasil, one of the first digital substations in the country.

I developed the application's front-end with React, Electron, and TypeScript, implementing real-time anomaly alerts, failure handling for asynchronous operations, and interactive dashboards for multi-level analysis. I was also responsible for much of the user experience, designed from Human-Computer Interaction studies with the system's operators.

This was my first contact with the IEC 61850 standard, which I later adapted to electric bicycles in the MoveUFF project. I also developed the front-end of the company's website.
