About
Most data people own one layer of the stack. I build the whole chain, from the Fabric pipeline to the pixel your board looks at, and lately the AI agent that answers their follow-up question.
As a driven data analyst and Power BI developer, I believe that teamwork, organization, and flexibility are the key ingredients for success. My core skills include data analysis, data visualization engineering, and data discovery and modeling, using AI where it has its place. While business decisions can often be based on gut feeling, why not back them up with data?
Data only drives action when it connects with human cognition. I design data visualizations based on cognitive design principles, making insights instinctual, decisions faster, and impact bigger.

Semantic modellingDAXPower Query M
How I help
Capturing your specific business logic within robust, reusable semantic models (data models, relationships, and advanced DAX). I ensure you stop reinventing the wheel with disconnected reports, establishing a single source of truth that is fully optimized and primed for AI integration.
03
Data Storytelling & Bespoke Visuals
Dashboards built on cognitive design, and custom visuals when standard charts fall short.
HTML / CSSSVGD3.jsPython
How I help
Most dashboards fail on adoption, not data. I design interfaces rooted in cognitive psychology principles to speed up insight discovery. When standard charts fall short, I develop custom visuals tailored precisely to your requirements using HTML/CSS, D3.js, and Python.
04
Cloud Data Analytics & Data Marts
Clean data marts and golden layers across Databricks and Microsoft Fabric.
SQLDatabricksMicrosoft FabricDBT
How I help
For data challenges that go beyond the dashboard layer. I write optimized queries, clean raw datasets, and structure them into clean data marts and 'golden layers'--delivering seamless analytics across both Databricks and Microsoft Fabric.
05
Advanced Analytics & Deep-Dive Research
Statistical deep dives into high-impact questions, like churn drivers or weather effects on sales.
PythonSQLStatistics
How I help
For complex business questions that go far beyond standard operational dashboards. Utilizing Python and SQL, I run deep-dive research projects to extract actionable statistical truths. I help you solve high-impact puzzles, such as uncovering the underlying drivers of customer churn or calculating exactly how external variables like weather anomalies impact your sales performance.
06
Fabric & Power BI Architecture & Governance
Secure, healthy and scalable Fabric and Power BI environments, behind the curtain.
Tenant settingsSecurityHealth checks
How I help
Setting up and maintaining what happens behind the curtain. From workspace tenant settings and strict security implementation to deep-dive health checks across your Fabric and Power BI environments, ensuring your platform remains highly performant, secure, and manageable as your organization scales.
07
Agentic BI Development
AI agents on governed semantic models, both for building BI and for using it.
MCPFabric Data AgentsCopilot
How I help
AI agents are changing both how BI is built and how it is used. On the development side, I connect agents to semantic models via MCP to automate repetitive work, from generating and documenting DAX to model reviews at scale. On the user side, I build Fabric Data Agents and Copilot experiences on top of governed semantic models, so people can ask questions in plain language and get answers grounded in your business logic, not hallucinated KPIs.
