About

HR leaders make million-dollar workforce decisions based on incomplete data. I make sure they don't have to. I'm a People Analytics Expert with 8+ years building the full stack — from raw data pipelines to boardroom-ready dashboards. Currently at Jazz (Pakistan's largest telecom), I own end-to-end HR analytics covering Talent Acquisition, Headcount, Payroll, Leaves, Age & Tenure, Exit/Turnover, and ASR — across thousands of employees. What I actually do: — Build and maintain ETL pipelines (SQL Server, Redshift, Azure) that replace hours of manual data work — Design Power BI dashboards that HR and C-suite actually use to make decisions — Write complex SQL for workforce segmentation, attrition analysis, and payroll reconciliation — Model predictive attrition and cohort analyses that shift HR from reactive to strategic — Work heavily in Excel for ad hoc analysis, data validation, and executive reporting Beyond HR, I've built a Macroeconomics Dashboard integrating FRED, stock market, and CFTC data — showing I can work across domains when data complexity demands it. On Upwork I'm Top Rated Plus with 1,800+ hours and 100% JSS, working with clients across legal, marketing, and financial analytics. If you're a company that needs someone who can own your data infrastructure and translate it into HR strategy — let's talk.
