Experienced Economist & Data Specialist / 10+ Years in Statistics I am a dedicated professional with a Bachelor's degree in Economics and a proven track record of managing complex datasets. I specialize in turning chaotic information into clear, accurate reports. My Expertise: 13 Years in Statistical Analysis: Extensive experience in data collection, verification, and cleansing for official statistics. Financial & Inventory Accounting: 5 years of experience in cost calculation, pricing, and inventory management (Libro system). Business Mindset: As a former business owner, I understand the importance of accuracy, deadlines, and cost-efficiency. I offer high-quality Data Cleansing, Financial Reporting, and Research services.

I turn messy data into clear, actionable insights. Data is only useful when it tells a story. If you’re struggling with scattered spreadsheets or complex databases that don’t give you the answers you need, I’m here to help. I specialize in Tableau and SQL, focusing on creating dashboards that don’t just look good but actually help you make decisions. I don’t just build tables — I find trends, highlight anomalies, and automate your reporting so you can focus on growing your business instead of manually updating Excel files. What I can do for you: Dynamic Dashboards (Tableau/Power BI): Transforming raw data into interactive visualizations that even a non-technical person can understand. SQL Data Analysis: Writing and optimizing queries (PostgreSQL, BigQuery, MySQL) to extract the right data efficiently. Data Cleaning & Transformation: Fixing "dirty" data and preparing it for accurate analysis. Business Insights: Identifying patterns and KPIs that matter to your bottom line. I believe in clear communication and meeting deadlines. Whether it’s a quick SQL fix or a comprehensive Tableau project, I treat your data with the precision it deserves. Let’s connect and make your data work for you.

Businesses lose thousands of hours a year to manual data entry and repetitive workflows. I build the AI systems that eliminate that permanently. What I deliver: — Invoice & document extraction (YOLOv8 + OCR, structured JSON output, 95%+ accuracy) — Business process automation (Python, n8n, Make, API integrations) — Computer vision systems (defect detection, object counting, real-time camera analysis) Every project I deliver is production-ready, documented, and built to scale. I don't disappear after handoff. Currently available for fixed-price projects and retainers. Message me with your bottleneck — most projects scope out in one conversation.
