What I'm looking for

I seek a collaborative environment that fosters innovation and growth in data science.

I am a dedicated data scientist with a strong background in predictive modeling and data analysis. At Sand Technologies, I developed a model that significantly improved lead conversion rates, allowing sales teams to focus on high-potential opportunities. My role involved managing data collection and preparation for machine learning projects, ensuring accuracy and reliability in our findings.

In addition to my technical skills, I have experience in educational support and research assistance, where I honed my organizational and communication abilities. I have successfully led projects that required teamwork and coordination, such as developing a web app for automated news classification. My educational background includes a Data Science Vocational Certificate, an MSc in Chemistry, and a BSc in Geology and Chemistry, equipping me with a diverse skill set that I apply to my work in data science.
