I am a senior Power BI developer and Power BI consultant with over 10 years of experience in data analysis and business intelligence. I hold Top Rated Plus status on Upwork, with 1,000+ hours billed and a 100% Job Success Score. My background in both accounting and data science means I understand business strategy as well as the technology. This rare mix allows me to design Power BI solutions that are directly tied to real business value, not just nice-looking charts. I’ve served as a professor at leading data schools in Brazil and have mentored many professionals in analytics. Companies like iFood, Vale, ArcelorMittal, and Globo have trusted me as their Power BI consultant to transform their data into actionable insights through Power BI dashboards and end-to-end analytics solutions. Power BI Consulting Services – What You Get When you hire me for Power BI consulting services, you can expect to receive: ⭐ Interactive Power BI Dashboards: Visually engaging Power BI dashboards tailored to your KPIs, giving you and your team a clear view of the business at a glance. These dashboards follow best practices in data visualization and UX, so even non-technical stakeholders can derive insights easily. ⭐ Data-Driven Decisions with Power BI: I deliver actionable insights, not just pretty charts. By connecting operational data to strategic goals inside Power BI, I enable faster, informed decision-making. Clients often report improved efficiency and more confidence in their decisions after implementing my Power BI solutions. ⭐ Scalable Power BI Solutions: End-to-end data pipelines that grow with your business. From robust Power BI data models to clean ETL processes, I ensure your data foundation is solid. Need to integrate a new data source or implement AI insights later?

You're probably generating more data than you know what to do with. Most of it sits in dashboards nobody opens or feeds reports nobody trusts. I fix that. I've been on Upwork since 2016. Top 1% (Expert-Vetted). No agency, no team: just me, doing the work. Over 25 years building data infrastructure for Fortune 500 companies and startups across the US, Latin America, and Europe. Fintech, e-commerce, marketing, agribusiness. I've reported to CEOs as fractional CTO, served as data lead to C-suites, and embedded with existing teams when the situation called for it. Flexible on structure, less so on cutting corners. What I do: - Raw data becomes something actionable. Not dashboards that look impressive in meetings, but insights you'll actually use. Plain language for stakeholders, technical depth for engineers, depending on what the situation requires. - AI/ML systems that reach production. Not proof-of-concepts that stall in staging. - Infrastructure audits that surface what's hiding in plain sight. Most companies are a few changes away from meaningful cost reductions or untapped revenue. I can almost guarantee you're wasting 1/5 of your cloud cost right now - and find it. Technical stack: Python, R, SQL (MySQL/PostgreSQL/MS SQL), Snowflake, AWS, Azure BI: QlikSense, PowerBI, Tableau AI/ML: OpenAI, Anthropic Claude, custom models Integrations: SAP, Salesforce, Monday.com, Zoho, ActiveCampaign, and likely whatever else you're running Big data, forecasting, marketing analysis, GIS
