What I'm looking for

I'm open to remote roles worldwide.

At OneRF Networks, I worked daily in Python on data quality, exploratory analysis, and preparation of operational IoT datasets for analysis and modeling. I also contributed to data science work and commercial development of IoT solutions.

At Solstício Energia, I built a Python account scoring model that doubled qualified leads within three months, and a solar performance anomaly detection model that compared generation with weather-normalized baselines to flag soiling and trigger maintenance. I also delivered solar projects and developed the project department with computational tools.
