Nikhil T.

Power BI & Microsoft Fabric architect and Tableau expert with 16 years in BI, now delivering with an AI-accelerated workflow. I build the semantic models, DAX and Fabric / Databricks / Snowflake pipelines behind sales, finance and executive dashboards your leadership actually trusts, and I migrate Tableau to Power BI without losing business logic. With Claude, ChatGPT / Codex and Copilot built into every stage, work that used to take weeks now ships in days, with every number validated by me. 275 Upwork jobs, 7,500+ hours, Microsoft certified in Power BI, six Tableau certifications. If you're here, you probably have one of these problems: → Dashboards take forever to load, or the refresh keeps failing → Leadership doesn't trust the numbers because two reports show two answers → Your team still builds reports by hand in Excel or Google Sheets every week → You're moving from Tableau to Power BI, or putting Microsoft Fabric / Databricks / Snowflake behind your dashboards → You want analytics embedded in your own product for customers ⚡ AI-ACCELERATED DELIVERY: WEEKS OF WORK IN DAYS I use AI tools extensively across the build, so you get better solutions, faster: • Claude (Code & Cowork) and ChatGPT / Codex to draft DAX, SQL, Power Query and Python, test cases and documentation • Microsoft and Power BI Copilot for faster report building and Copilot-ready semantic models for your users • Working prototype in days, then rapid iteration on your feedback • Human validation: every measure is reconciled against source data before it reaches you 📊 DASHBOARDS I BUILD • Sales dashboard: revenue, pipeline, quota vs actual, forecast, rep and territory performance (Salesforce, HubSpot, CRM) • Marketing dashboard: campaign ROI, ROAS, CAC, leads and funnel (GA4, Google Ads, Meta Ads, LinkedIn, HubSpot, Search Console / SEO) • Finance dashboard: P&L, budget vs actual, cash flow, AR/AP (QuickBooks, Xero, NetSuite, SAP, Dynamics 365) • Executive KPI scorecards and management reporting • E-commerce and retail: Shopify, Amazon, inventory, product and customer analytics • Operations, supply chain, HR, customer service, healthcare & pharmacy KPIs and SaaS metrics (MRR, churn, retention) 🏗️ MICROSOFT FABRIC & DATA PLATFORM Lakehouse and warehouse design, Dataflows Gen2, notebooks and pipelines, Direct Lake models, Databricks and Snowflake behind Power BI, incremental refresh, deployment pipelines, governance and capacity tuning 🔄 MIGRATIONS Tableau to Power BI, Excel to Power BI, Looker Studio to Power BI, Qlik / Crystal Reports to Power BI or Tableau EXCEL, GOOGLE SHEETS & LOOKER STUDIO Advanced Excel dashboards, Power Pivot, VBA / Office Scripts, Google Sheets automation (Apps Script), Looker Studio on GA4, Google Ads and BigQuery 🔌 DATA SOURCES SQL Server, Azure SQL, Snowflake, Databricks, BigQuery, Redshift, PostgreSQL, MySQL, Oracle, SAP, Salesforce, HubSpot, Dynamics 365, NetSuite, QuickBooks, Xero, Shopify, Amazon, SharePoint, REST APIs, Excel Recent examples: ✅ Rebuilt a manual Excel workflow in Power BI and cut weekly reporting time by 70% ✅ Built Microsoft Fabric and Databricks lakehouse pipelines feeding live executive dashboards ✅ Delivered an embedded Power BI customer portal for a SaaS company ✅ Designed enterprise Power BI used by 15,000+ people, with RLS, governance and gateways done right 🏆 WHY CLIENTS HIRE ME (AND COME BACK) • 16 years in business intelligence and data analytics. 275 jobs, 7,500+ hours on Upwork • Microsoft certified in Power BI, six Tableau certifications, IIT Madras business analytics, MBA • I think like a business owner, not just a developer: every dashboard starts with the decision it must support • Clients describe me as "someone I reach out to when the work is complex" (see endorsements below) 🛠️ HOW I WORK 1. Written scope and KPI list before any hours are logged, so we agree on "done" 2. AI-assisted prototyping and early milestone previews, so you see progress in days, not weeks 3. Documented DAX / SQL, a handover walkthrough and a support window after delivery 4. NDA-friendly. AI speeds up the build; I personally review, test and validate every number TOOLS Power BI (DAX, Power Query, data modeling, semantic models, RLS, paginated reports, performance tuning, Embedded, Copilot) · Microsoft Fabric · Tableau (Desktop, Prep, Server/Cloud) · Databricks · Snowflake · Azure · SQL Server · BigQuery · Python · Power Automate · Looker Studio · Excel AI: Claude Code · Claude Cowork · ChatGPT · Codex · Microsoft 365 / Power BI / Fabric Copilot INDUSTRIES Finance, Healthcare & Pharmacy, SaaS, Retail & E-commerce, Marketing, Logistics, Manufacturing, Hospitality, Real Estate 🚀 LET'S START Send me three things: your data source, who will use the dashboard, and your deadline.
