I'm a CS student who sits at the intersection of technical depth and business impact — I don't just build things, I build things that answer a question, solve a problem, or drive a decision.
My work spans data analysis, full-stack web development, SQL data engineering, and interactive business intelligence — and I bring 4+ years of real-world commercial experience from working inside global retail operations at Zara and GUESS, where I learned how businesses actually run before learning how to analyze them.
I'm actively targeting roles in Data Analytics · Business Analysis · Software Development · Solutions Engineering · Technical Sales — positions where technical skills meet business outcomes.

Executive BI dashboard over 9,994 records ($2.3M revenue) — real-time Region × Category filtering, 4 live charts, 5 KPI cards. Built with zero frameworks. Includes a Python/Pandas ETL pipeline to automate data ingestion from raw CSV. Key result: Surfaced negative-margin products and regional revenue gaps as executive-ready, decision-prioritized findings. |
Full EDA on Toronto's short-term rental market — cleaned 15,000+ rows, engineered a revenue proxy feature, and ranked neighbourhoods by annual revenue potential. Key result: Quantified a 2.3× revenue gap between room types and validated availability as a demand signal via correlation heatmap (r = −0.34). |

Production-grade Star Schema warehouse — 4 dimension tables, 1 central Fact table, full referential integrity. Advanced SQL: RANK() window functions, CTEs, CASE-based segmentation. Key result: Identified that Gold-tier customers (10% of base) drive 40% of revenue and flagship shoppers show 25% higher AOV than outlet locations. |
Full client-server application — stateless two-endpoint REST API managing independent sessions for concurrent players. All game logic isolated server-side; vanilla JS frontend communicates purely via AJAX. Key result: Delivered a fully functional, demo-ready product end-to-end — system design, API architecture, UI, and deployment — with zero frameworks. |
