👋 Hello, I'm
Arizael Capote
Computer Science Engineer | Data Analyst | Data Scientist
I transform raw data into actionable insights through rigorous data analysis, Python automation, and interactive Power BI dashboards.
As a Computer Science Engineer, I build end-to-end data pipelines — from cleaning messy datasets with Pandas to deploying predictive models that drive business decisions.
I can build demanded Python solutions.
Encomienda al Señor tu camino; confía en él, y él hará. Hará que tu justicia resplandezca como el alba; tu justa causa, como el sol de mediodía.
— Salmo 37:5-6
Work Experience
My journey through labor market
Billing and operations
Walmart meat processing center · Costa Rica
Managed high-volume B2B invoicing using SAP and Excel, ensuring data integrity across ERP systems. Generated daily operational reports and provided data-driven support for logistics, dispatch, and personnel management — coordinating and supporting cross-functional operations in a high-demand supply chain environment.
Logistic Prediction
"Lo bueno con lo bueno" · Supply Chain
Implemented a demand forecasting model using Python (Pandas, Scikit-learn) and Power BI for a food distribution company. Cleaned and analyzed historical sales data, engineered features for seasonality, and delivered actionable dashboard that guided restocking decisions across 7 product categories.
My Projects
Things I've built along the way
QR Code Generator – Desktop Automation Tool Built with Python
A lightweight Python desktop (Windows) application built with Tkinter that converts URLs, text, and numeric data into scannable QR codes. Features an intuitive GUI for instant generation — useful for inventory labeling, event check-ins, and digital business cards. Also can scan images to read QR. (It´s free to use)
Demand Forecasting & Sales Prediction with Python and Power BI
Ad-hoc Demand Forecasting Analysis: Designed a 90-day demand prediction model for a food distributor using Python and Prophet, analyzing 6+ months of historical sales data.
Hotel Booking System – Backend with Django
Designed and built a full reservation management system using Django, and Bootstrap. Implemented clean relational data models for room availability and booking logic.
Geospatial Data Automation – Raster Extraction with Python and QGIS
Automated the extraction of raster terrain parameters from geospatial datasets using Python scripting within QGIS. Replaced a manual multi-step GIS workflow, reducing processing time by over 80% and ensuring full reproducibility of spatial analyses for environmental and agricultural studies.

Learning Path
My journey from Computer Science to Data Science & AI
My journey blends formal Computer Science training with self-driven Data Science mastery. Since 2023, I've built a practical data stack: Python (Pandas, NumPy, Scikit-learn), SQL for querying, and Power BI for business-ready dashboards. I've taken projects from messy raw data to deployed models that drive real decisions. Now I'm pushing into AI automation — LLMs, prompt engineering, and pipeline orchestration.
