About this Gig

As a Computer Engineer specializing in Data & Product Analysis, I bridge the gap between raw data and strategic decision-making. I don't just create charts; I build reliable data infrastructures and perform deep-dive audits to ensure business integrity.


My expertise includes:

  • Data Cleaning & Wrangling: Using Python (Pandas) to transform messy, unformatted records into structured, high-quality datasets.


  • Advanced SQL & Database Management: Expert in complex queries, table consolidation (e.g., UNION ALL, Joins), and data architecture.


  • Power BI Business Intelligence: Designing interactive dashboards that track KPIs, seasonality, and conversion metrics.


  • Data Auditing & Transparency: Experience analyzing large-scale public procurement data to identify patterns, anomalies, and spending asymmetries.


Why choose me? I apply a Stoic and analytical methodology to every project, focusing on technical precision and real-world impact. Whether you need to fix a broken database, automate a report, or gain deep insights into your sales performance, I provide scalable solutions built with engineering rigor.


I am ready to help you unlock the true value of your data. Lets get to work.
