AI-Native Data & Analytics Engineer

Business Intelligence • SQL • Python • Power BI • Data Pipelines • Decision Intelligence • AI-Augmented Analytics Automation

I build analytics and decision-support systems that transform operational, commercial, marketplace, CRM, and supply-chain data into KPIs, dashboards, automated workflows, simulations, risk assessments, and executive-ready business recommendations.

My current work is centered on AI-native analytics engineering: using artificial intelligence as a technical execution infrastructure to industrialize analytical production across SQL, Python, Power BI, DAX, ETL, dashboards, documentation, validation, and reproducible data workflows.


AI-Native Analytics Methodology

I have moved beyond the traditional manual analytics development model, where productivity is limited by syntax memorization, formula recall, or step-by-step operation inside specific tools. I use AI systems as an integrated technical execution layer: an instant expert knowledge base, code generation engine, logical architecture adviser, validation assistant, documentation accelerator, and high-speed analytical production force.

This does not mean replacing analytical judgment with automation. My role is to define the business problem, structure the KPI logic, provide data context, direct AI-assisted iterations, test outputs, validate results, correct inconsistencies, and turn generated work into functional, reproducible, and scalable analytical systems.

In practice, I use this workflow to convert business objectives and real datasets into:

  • Python scripts for cleaning, modeling, visualization, automation, simulation, and reporting.
  • SQL queries for joins, aggregations, KPI logic, analytical datasets, validation checks, and reporting layers.
  • DAX and Power Query logic for BI models, measures, transformations, and executive dashboards.
  • ETL and data pipeline workflows for extraction, transformation, validation, documentation, and repeatable execution.
  • Tool-agnostic analytics solutions that can be implemented through Power BI, SQL, Python, dashboards, notebooks, reports, or automated pipelines depending on the business problem.

This methodology transforms manual BI and data-analysis work into industrialized, AI-augmented, human-validated analytics production focused on speed, traceability, quality, and decision-making.
