Title: Data Analyst | Power BI, SQL & Excel | Turning Millions of Rows into Decisions ⸻ Overview: I help businesses that are drowning in data — from messy spreadsheets to millions of rows of enterprise data — turn it into dashboards and insights leadership actually uses. Over 2+ years, I’ve built dashboards spanning finance, HR, and sales, including monthly income/expense/savings tracking, employee attrition and workforce KPIs, and multi-region sales performance analysis. ⸻ A few examples from my portfolio: • Finance Dashboard — automated income, expense, and savings tracking across multiple years, surfacing metrics like savings growth % and total portfolio value in one live view • HR Analytics Dashboard — analyzed workforce data for 889 employees, tracking attrition rate, average tenure (7 years), average salary, and job satisfaction by department • Sales & Customer Insights Dashboard — tracked salesperson-level performance across 10+ reps and multiple regions, with individual sales totals up to $1.9M • Streaming Analytics Dashboard — analyzed 519 categories and thousands of titles across genres and countries to surface content and audience trendsI’m What I can do for you: • Data cleaned and modeled for accuracy at scale — no shortcuts that break under load • SQL queries optimized for speed, not just correctness • Power BI dashboards built around the 3-5 KPIs that actually drive decisions — not 40 charts nobody opens • Clear, plain-language insights a non-technical stakeholder can act on immediately Tools & Skills: Tools: Power BI · SQL · Excel (Pivot Tables, Power Query) · Data Cleaning.Data Modeling · ETL.Stroytelling ⸻ Why work with me: • I’ve handled big data at company scale, so your dataset size won’t slow me down • I ask about your business goal before I build — the dashboard serves the decision, not the other way around • Fast turnaround, clear communication, revisions until it’s right

Most dashboards fail the same way. The numbers don't tie out, the refresh breaks the moment the source changes, and within a month the team is back in Excel checking the dashboard by hand. That happens because whoever built the report was never allowed near the data underneath it. I do both halves. That's why my dashboards survive contact with real data. WHAT CLIENTS SAY Every Upwork job I've finished that got rated came back 5.0, and clients keep tagging the same three things: Committed to Quality, Clear Communicator, Accountable for Outcomes. "Absolutely exceptional work! Expert for sure!" "Efficient, professional, and really understood what I needed. The dashboard is super intuitive." "Mostafa did an excellent job. He was very kind and exceptionally patient." THE ENGINEERING HALF In my full time role I built and run a food manufacturing group's entire analytics platform, alone. NetSuite ERP pulled with Python into a BigQuery warehouse in bronze, silver and gold layers, refreshing unattended on Cloud Run every day. On top of it sits one Power BI model: 64 tables, 673 DAX measures, 14 published reports, one definition per metric. It also runs a verification step that catches a broken column before it reaches a dashboard as a silent zero, which is the failure nobody notices until a board meeting. Python, SQL, Google BigQuery, ETL and ELT pipelines, star schema and data modeling, incremental refresh, Cloud Run and Cloud Scheduler, REST APIs, Google Apps Script. THE ANALYTICS HALF Power BI and Looker Studio dashboards for marketing, sales, finance and operations teams. Recent work here: an ads performance dashboard tracking spend across Meta, TikTok and Snapchat, a content and sales ops analytics dashboard, and a Power BI report rebuilt from a layout that wasn't working. Power BI (DAX, Power Query, semantic models), Looker Studio, GA4, Google Search Console, Google Ads, Meta Ads, TikTok Ads, Snapchat Ads, Excel, Google Sheets. WHAT YOU ACTUALLY GET A data model, not just a screen. Ask a new question next quarter and it answers without a rebuild. Metrics defined once. Revenue means the same thing on every page, in every report. A refresh that runs itself on a schedule, plus a check that tells you when a source breaks instead of quietly showing zero. A short handover walkthrough so your team can maintain it without me. HOW I WORK I start small on purpose. One page you can react to first, then the rest. You see something real in the first few days instead of waiting two weeks for a reveal, and you get progress updates the whole way.
