What I'm looking for

I seek roles applying data science and quantitative methods to finance, with opportunities to automate processes, build ML models, and deliver actionable visualizations within collaborative, growth-focused teams.

I am a data scientist with a strong focus on financial analytics, automation and quantitative modelling, combining academic training in Data Science with practical experience at Siemens and multiple finance-focused extracurricular roles.

At Siemens I develop digital solutions that automate processes and convert IT financial data into visualizations that compare actual costs to forecasts, improving decision-making. I have applied machine learning and statistical techniques such as Copulas, pairs trading and mean reversion to build quantitative finance models and improve predictive accuracy.

I have led finance initiatives as Vice President of a trading club, managed significant event budgets and partnerships, and completed international exchange study in South Korea—bringing cross-cultural agility, technical fluency in Python/R/SQL and strong stakeholder communication to deliver measurable impact.
