A concise record of analytical, digital and technical projects. This page is intentionally simple: project, context, tools and direct evidence through case-study pages and full analysis reports.
Educational and portfolio projects that demonstrate data preparation, analysis, visualization and business interpretation.
Analyzed fictional product and customer data to evaluate sales-growth quality, product profitability, discounts, receivables and customer economics.
Built customer-grading logic and a management KPI framework to turn the analysis into decision-oriented recommendations.
The public portfolio intentionally excludes the original recruitment document and company-identifying material.
Analyzed 17K+ hourly and 731 daily observations to compare registered and casual users across time, weather, season, holidays and working days.
Validated consistency between hourly and daily datasets and derived clear user-behavior patterns for operational and marketing interpretation.
Cleaned and explored the Book-BX dataset, then applied association-rule mining to identify meaningful co-occurrence patterns among books.
The project demonstrates an end-to-end data-mining workflow rather than listing R only as a standalone skill.
Analyzed three years of educational sales data across products, customers, sales representatives, seasons and sales channels.
Focused on recurring sales patterns and commercial insights rather than visualization alone.
Public web work and technical systems experience kept separate from the analytics portfolio.
Designed and deployed this personal website as a clear home for my resume, selected work and contact information.
Website implementation and VoIP technical work for Callio, a cloud telephony company.
Detailed VoIP architecture and configuration claims are intentionally omitted until the implementation documentation is fully reviewed.
The resume contains experience, education, coursework, training, skills and portfolio highlights.
