Kliuber M.

Power BI Developer

I’m a bilingual (English/Spanish) Data Analyst and BI Developer with 5+ years of experience supporting fast-paced operational environments. I specialize in designing scalable reporting solutions, building robust data models, and automating workflows from data extraction and transformation to visualization and delivery. My experience includes developing end-to-end BI processes using SQL, Power BI, Power Query, Python for API integrations, and automation tools. I focus on data integration, ETL processes, clean data modeling, KPI tracking, and transforming complex datasets into actionable insights through reliable business intelligence solutions. I’d be glad to support your analytics initiatives. My Approach: Kickoff & Discovery Session We start by understanding your business, goals, and the process you'd like to visualize. Together, we define key KPIs, reporting needs and design preferences to ensure we're on the same page from day one. Data Access & Understanding I review your data sources, structure, and update frequency to assess readiness. This includes identifying any quality issues, understanding data relationships, and ensuring access is secured to begin modeling accurately and efficiently. ETL – Data Preparation I clean, transform, and organize your data into a usable format. This includes creating lookup tables, applying consistent formatting, and preparing the foundation for a high-quality, scalable report. Data Modeling I define relationships between tables, apply a logical schema (often star schema), and build hierarchies and calculated columns as needed. The focus is on performance, accuracy, and a structure that supports meaningful analysis. DAX Modeling Here I build dynamic KPIs and measures using DAX — from time intelligence to filter-aware metrics. I validate calculations to ensure results are trustworthy, aligned with your business logic, and ready for decision-making. UX & UI Design The final step focuses on creating a clean, intuitive report that reflects your branding. I design for clarity and usability with smart layouts, filters, drill-throughs, and navigation — ensuring users get insights quickly and confidently.
