🏆 Microsoft Certified Solution Expert (MCSE) - Data Management & Analytics 🏆 Microsoft Certified: Power BI Data Analyst Associate 🏆 SnowPro Core Certified 🎓 Master of Data Science, Universiti Malaya 📊 9+ Years in Data Analytics & Business Intelligence | Power BI, Snowflake, SQL, DAX Hi, I'm 'Aisyah - a Business Intelligence Consultant and Data Analyst with over 9 years of experience turning messy, scattered data into dashboards that leadership teams actually use to make decisions. I currently lead enterprise Power BI delivery as a Consulting Manager, and before that built analytics solutions at Accenture, AirAsia, and KPMG across real estate, travel, cloud, and F&B sectors. A few results I'm proud of: 📈 Cut Power BI dashboard load times from 120+ seconds to under 60 by optimizing DAX measures and data models 📉 Reduced manual reporting effort by 80% by automating recurring reports (telephony performance, warranty workflows) in Power BI 💰 Built an automated cloud cost monitoring dashboard tracking Snowflake, Fivetran, and Azure spend for leadership visibility 🏗️ Architected a centralized BigQuery data warehouse integrating Firebase and Google Analytics, lifting funnel-tracking accuracy from ~75% to over 95% 👥 Delivered executive-facing dashboards used directly by VPs and Heads of Technology 🚀 What I Can Do For You ✅ Power BI Development - data modeling, DAX, Power Query, performance tuning, RLS/governance ✅ Data Analysis & Cleaning - SQL, Python, EDA, transforming raw data into reliable, analysis-ready datasets ✅ Dashboard & Report Design - Power BI and Looker Studio dashboards built for real business usability, not just pretty charts ✅ Cloud Data Platforms - Snowflake, BigQuery, Azure Synapse, Fivetran integration ✅ BI Strategy - KPI definition, reporting standards, and stakeholder alignment from analyst to executive level 💡 Services 📊 Power BI Development & Dashboard Design 📊 Looker Studio Development 🧹 Data Cleaning & Transformation 🔍 SQL Query Writing & Optimization 📑 Data Visualization & Reporting Automation 🧠 BI Strategy & KPI Design 🎯 How I Work I start by understanding the business question before touching the data - a dashboard is only useful if it answers the right question. I communicate clearly throughout the project, flag trade-offs and assumptions as I go, and deliver on the timeline I commit to. Let's talk about what your data could be doing for you.
