What I'm looking for

I seek a data-focused role where I can build scalable pipelines, improve data reliability, and deliver insights; I value collaborative teams, technical ownership, and measurable operational impact.

I am a data engineer and analyst with dual master's training in Computer Science and Information Systems Management, focused on building scalable ETL pipelines, data models, and visualization solutions. I have delivered production-ready data workflows, optimized high-frequency imaging and operational datasets, and built full-stack dashboards that turn complex time-series data into actionable insights.

My experience spans industry and research — from reducing imaging processing time by 70% to automating Python workflows that processed millions of SKU records — and I combine strong technical skills (Python, SQL, AWS, Pandas, D3.js) with practical operational impact and leadership organizing large events and student organizations.
