Rafiullah K.

I build Power BI dashboards, automated ETL pipelines, and SQL Server data models that replace manual reporting with systems that update themselves. 8+ years in business intelligence, 1,800+ Upwork hours, 100% Job Success, and 10+ enterprise dashboards delivered this year. Most reporting problems are not visualization problems. They are data problems. A dashboard that pulls from a broken model or a manual export will be wrong within a month. I fix the layer underneath first, then build the report on top of it, which is why my dashboards keep working after handover. I lead people analytics at Jazz, Pakistan's largest telecom, where I built ETL pipelines connecting Workable ATS, Redshift, and SQL Server that cut 15 hours a week of manual data prep, and optimized DAX and data models to improve refresh performance by 40%. I take on a limited number of freelance builds alongside that work, and my average response time on Upwork is under 4 hours. WHAT I BUILD Executive BI Dashboards: KPI scorecards, financial and sales reporting, C-suite views Automated ETL Pipelines: CRM, ATS, HRIS, and cloud sources into SQL Server or your warehouse Power BI Audits and Rebuilds: fixing slow refreshes, broken models, and unreliable DAX Data Modeling: star schema design, relationship logic, time intelligence HR and Workforce Analytics: attrition, headcount, payroll, talent acquisition PROVEN RESULTS 40% faster refresh through DAX and data model optimization across 10+ dashboards 15 hours a week saved through ETL automation at an enterprise telecom 80% reduction in manual reporting through SQL workflow automation for marketing analytics 20% retention improvement from cohort analysis and customer segmentation 15% ROI increase from Power BI and Python campaign performance dashboards TECH STACK Power BI, DAX, Power Query, SQL Server, T-SQL, Python (Pandas, NumPy), Redshift, BigQuery, Snowflake, REST APIs MS Data Science | Microsoft Power BI Data Analyst Certified | Top Rated | 100% Job Success Tell me what data you have and what decision you are trying to make with it. I will tell you exactly what I would build, and how long it would take.
