Most BI projects fail for the same reasons — dashboards no one opens, reports built by hand every Monday, and data spread across five tools that don't talk to each other. I help teams fix that. I build dashboards people actually use, automate the reports that eat your week, and turn scattered data into something you can decide on. WHAT I CAN HELP WITH → A Power BI or QuickSight dashboard that loads fast and answers the questions your team is actually asking → Moving messy Excel reporting into something automated and trustworthy → Building a clean SQL data model behind your dashboards so numbers stop disagreeing → Product and conversion analytics setup (Mixpanel, GA4) so you finally see where users drop off → A second pair of eyes on an A/B test, funnel, or KPI structure that doesn't feel right → Migrating legacy Tableau or Excel dashboards into Power BI or Amazon QuickSight WHAT I DO → Dashboard development → Power BI, Amazon QuickSight, Tableau, Looker Studio → Data modeling → DAX, Power Query (M), star schema, calculated measures → SQL Queries → PostgreSQL, Amazon Redshift, AWS Athena, Oracle, SQL Server, MySQL, BigQuery → Product analytics → Mixpanel, event tracking, funnel analysis → Reporting automation & Data Analysis → Python (Pandas, NumPy, Matplotlib), Power Automate, Make, Zapier, Excel → Executive reporting → KPI scorecards, drill-downs, mobile-ready layouts → Data cleaning & ETL → multi-source integration, validation, refresh schedules INDUSTRIES I WORK WITH Banking, fintech, telecom, digital products, e-commerce, and SaaS. If your data lives in AWS, a SQL database, an ad platform, or a spreadsheet someone refuses to give up, I can probably work with it. HOW I WORK Short discovery call or chat to understand what decisions the dashboard needs to support. A working draft within the first week so we iterate on something real instead of a spec. Documentation and a short handover so your team isn't dependent on me to keep using it.

I’m a data storyteller specializing in Tableau and modern BI — building dashboards that feel less like reports and more like products. Over the past 5 years, I’ve delivered 50+ dashboards and 14 end-to-end BI applications across Finance, Retail, and HR. From pipelines processing billions of rows to lightweight self-serve analytics, my focus stays consistent: turning raw, messy data into structured, reliable systems — and presenting it in a way people actually want to use. What sets me apart is the combination of three layers: data modeling, transformation, and visual design — all treated as one cohesive experience. I don’t just build dashboards. I design interfaces for decision-making. No clutter, no confusion, no need for explanations — just clear logic, strong hierarchy, and intuitive flow from question to answer. What I bring: • Tableau, Power BI, Qlik Sense — with a strong focus on UI/UX and visual clarity • End-to-end data transformation: dbt, SQL, Python (from raw data to production-ready models) • Modern data stack: Snowflake, BigQuery, Airflow, Fivetran • Dashboards used by 5000+ daily users • ETL automation saving teams 20+ hours per week • Led large-scale BI migrations (Tableau ↔ Qlik, Power BI → Tableau) • Strong product analytics background: funnels, retention, LTV, experimentation I’m especially interested in work where structure meets aesthetics — where clean data models, thoughtful transformations, and sharp visual design come together into one system that just works. Whether you need a high-impact executive dashboard, a scalable analytics layer, or a full rebuild of your BI stack — I focus on making it not only functional, but seamless. Let’s turn your data into something people actually want to open.
