Over mij
I'm a data scientist specialising in data cleaning, classification, and machine learning. I've worked with large-scale datasets in production environments, building models and turning messy, complex data into clear insights that drive real decisions.
With a background in Information Systems and Business Analysis, plus Google Professional Certifications in Data Analytics, I bring both technical depth and business context to every project — so you don't just get numbers, you get answers.
If you need clean data, a well-trained model, or sharp analysis that actually means something, let's talk.
