What I'm looking for

I’m looking for a role where I can apply data analysis, machine learning, and financial analytics to deliver operational intelligence—working autonomously, documenting clearly, and producing measurable dashboards, KPI tracking, and reporting outcomes.

I’m a detail-oriented, research-driven practitioner with a Master of Science in Financial Engineering and more than four years of experience in analytics, operations, and data-driven reporting. I bring independent project delivery, systems thinking, and disciplined inquiry, with a focus on turning complex ideas into meaningful outputs.

I combine quantitative training with practical business problem-solving, with particular interest in data science, financial analytics, machine learning applications, and operational intelligence. I’m recognized for accuracy, ownership, analytical rigor, and my ability to work independently in remote and cross-functional environments—supported by clear documentation and leadership-ready reporting.
