Hire the Best Data Modeling Specialists
in Brazil

If your data pipeline breaks, your team stops trusting the numbers and bad decisions start happening. That's the problem I work on. For 19 years I've built data systems inside financial institutions where bad data costs real money. At Master Bank, I replaced a 3-day manual reporting cycle with a 30-minute automated system that catches bad data before it spreads. Most pipelines fail because validation is missing, not because of scale. What changes when you work with me: Your pipelines catch errors before running on bad data. Your reports arrive on time, with alerts when something breaks. Your team gets documentation they can actually use. Your data quality becomes automated, not manual. Recent project: Full data migration platform for a US-based SaaS company. Every record validated automatically, with zero silent failures and 95%+ success rate. Client rating: 5.0/5.0. Quote: "quality of work and attention to detail were especially appreciated." Stack: Python, SQL, dbt, AWS, Machine Learning. I work best with fintechs, SaaS companies, and data teams that need reliable pipelines. Where is it breaking today: ingestion, transformation, or the final numbers?

Senior Power BI developer with 15 years building dashboards executives actually open on Monday morning - not the ones sitting in SharePoint collecting dust. I write complex DAX, architect Microsoft Fabric warehouses, automate workflows with Power Automate, and integrate NetSuite, Dayforce, QuickBooks, and Shopify data into clean, trusted reports. Here's what usually happens: a company has data scattered across systems and nobody trusts the numbers because every department has a different version of the truth. I come in, connect everything, build a proper data model, and deliver dashboards that update on their own and actually match the source systems. What I do: → Power BI & DAX — KPI dashboards, financial reports, operational views. Complex DAX measures, star schema design, row-level security, model optimization. I've taken bloated datasets and compressed them from gigabytes to a fraction so reports stop crawling. → Microsoft Fabric & SQL Warehouse — stored procedures, fact and dimension tables, materialized views, end-to-end data pipelines. Built warehouses serving 50+ locations with company-wide reporting. → Power Apps — apps that kill paper forms and manual spreadsheets. Data entry, field inspections, approval screens - connected to SQL, SharePoint, whatever you're already using. → Power Automate — workflow automation, Teams alerts with Adaptive Cards, scheduled jobs, API calls. If your team is still copy-pasting data between systems every week, that's what I fix. → Integrations — NetSuite, QuickBooks, Dayforce, Klaviyo, Shopify, Dynamics 365, REST APIs. If the system has an API or a connector, I can get that data into your reports. Industries: energy & oil and gas, banking, pharma, manufacturing, e-commerce, medical devices, HR analytics. Microsoft Certified: Power BI Data Analyst Associate. Based in Brazil (GMT-3) but I work US hours and speak English every day with American clients — no communication issues. If any of this sounds like what you need, drop me a message with a short description of your situation. I'll be honest about whether I'm the right fit.

When your operations are running blind, every day costs you money. I help manufacturing and operations companies build the data systems that give leadership real visibility — so problems get caught early, decisions get made faster, and KPIs actually drive behavior. What makes me different: I've sat in your chair. As a Shift Manager I led 100+ person teams. As a Process Improvement Manager I reduced production stoppages by 85%. As a Project Manager I delivered $1M+ in savings. I know which questions to ask because I've lived the problems you're trying to solve. As a dropshipping E-commerce operations manager I built multi-channel sales reporting from scratch — ingesting Amazon Seller Central data, allocating courier and channel info, and calculating profits and operational kpis. Improved profit in 32%, refunds recovery in 41+% and reduced order defect rate by 37% with data/process improvements. What I build: • Power BI dashboards that support real decisions (not just display data) • KPI frameworks that align teams to measurable results • Real-time operations monitoring systems • Process improvement roadmaps with clear ROI My stack: Power BI · SQL · M · DAX · PowerQuery · RLS · dbt · Python API integration · GitHub · M365 · ERP · Syspro · Excel · Google Sheets Credentials: · Power BI Associate · WCM International Auditor · Lean Office Consultant · Master's in Automotive Engineering (Politecnico di Torino) · Mechatronics Engineer Most consultants ask "what dashboard do you want?" — I ask "what problem are you trying to solve?" Then I diagnose root causes, develop the right KPIs, and build systems your team will actually use. 📧 Let's talk about what's possible with your data.
