About me

Clear dashboards. Real insights. Smarter decisions. Open to Data Analyst roles across the UAE.

I’m Omer, a Dubai-based Data Analyst who enjoys finding the “why” behind the numbers. Since graduating in Computer Science and Engineering (2025), I’ve earned my Microsoft PL-300 certification and built dashboards and analyses with Power BI, SQL, Python and Excel. Today, I’m part of the Amazon People Analytics Externship, using employee reviews to uncover why new hires leave early and how to keep them longer. My next step is a full-time Data Analyst or BI role in the UAE. I hold a valid UAE visa, and I’m also open to internships.

Overview

Tailwind Traders is a global retailer selling across several countries and currencies. Leaders needed one place to see sales and profit clearly, without converting numbers by hand. I built a multi-page Power BI executive dashboard that brings everything together in a single, easy-to-read view.

Tailwind Traders Sales & Profit Dashboard

What I've accomplished

- Designed a star-schema data model linking 6 datasets - Cleaned and shaped the data in Power Query - Wrote DAX measures for key KPIs like sales and profit - Automated multi-currency conversion so every country reports in one currency - Added drill-downs to go from a global view to country-level detail

Outcome

The dashboard lets leaders compare sales and profit across countries in seconds instead of juggling separate reports. Building it taught me how a strong data model simplifies DAX and speeds up dashboards, and how to design for executives who want answers at a glance.

Amazon Operational Strategy & People Analytics Externship

Imagine shaping how AMAZON — yes, THE Amazon — welcomes and keeps its workforce. Every year, Amazon loses billions because new hires leave before Day 90. You’re going to fix that. In this externship, you’ll web scrape real-world employee reviews from across the web, extract actionable insights, and design persona-driven strategies to help Learning Ambassadors connect smarter, faster, and more humanely. It’s part research, part strategy—and all about learning how people data drives big decisions.

Data AnalysisPythonStrategyOperations

Overview

The externship combined operational strategy and people analytics to investigate early-career attrition at Amazon fulfillment centers. The work gathered and analyzed employee feedback sources, extracted patterns across roles and tenure, and translated those patterns into persona-driven recommendations. Deliverables included scraped review datasets, coded thematic findings, and candidate personas.
