What I'm looking for

I am a data analyst/scientist with three years' experience in fintech, focused on extracting meaningful insights from complex datasets and delivering data-driven solutions. I have built dashboards, automated reporting, and led data-preprocessing and mining efforts that improved model accuracy and operational efficiency.

My work has increased business process coverage, reduced planning time, and boosted team effectiveness through Python-driven reports, CI/CD dashboards, and autonomous services. I collaborate closely with cross-functional teams and present metrics to stakeholders to drive measurable improvements.
