About Me

Hi, I’m Karine! I'm a data scientist who enjoys turning messy data into practical, real-world solutions.

I’ve been coding since 2017 across business functions - from customer analytics to supply chain operations. All the while, focusing on bridging the gap between data, machine learning, and business impact.

I build data science and ML systems end to end, from experimentation and modeling to production-ready analytics tools. My work includes predictive modeling, experimentation frameworks, and LLM-powered applications designed for real use, not just demos.

Always learning, always building. Let's connect:
