Hi there!

I'm a system engineer and data scientist with a passion for positive change. I specialize in integrating diverse technologies, including backend development, standalone software, machine learning, and frontend solutions. I am committed to delivering innovative and eco-friendly solutions, leveraging my strengths in problem-solving and efficiency.

Work Projects

E-learning Platform

Developed an internal education management platform to facilitate part-time work integration within a company. The platform streamlined educational processes and provided an interface for managing educational content.

Survey Management System

Created a user-friendly survey management system designed to streamline survey processes and enhance administrative features. This project aimed at improving the efficiency of survey data collection and management.

Document Creation System

Automated the creation of documents by formatting data from a database into predefined layouts. This automation significantly reduced manual effort and increased efficiency.

ArcGIS Automation

Automated ArcGIS routines that could be exceuted through a batch file.

Performance Analysis System

Created an internal performance analysis system with Excel VBA and Power Query to visualize key metrics over time, making forecasts and enhancing data clarity and helping leaders focus on areas for improvement.

Permit Management System

Developed an online automation system using Google Apps Script, Google Sheets, and Google Forms to streamline permit applications and surveys across company branches and departments. The system automatically notifies the responsible leader via email to review and sign documents.

Geolocation Retrieval Tool

Created a software tool that automatically retrieves the geolocation of addresses using the Google Maps Geocoding API. Integrated into Excel, this tool allows users to quickly obtain geographic coordinates for multiple addresses.

Governmental System Update

Added new features to a governmental vehicle license plate system by implementing predefined features to improve functionality and efficiency.

Training Projects

Docker Testing

Wrote a code for docker containers that run a few tests on a server.

FastAPI Testing

Wrote a code for an API to access data from a database (Excel) using FastAPI.

Private Projects

Ancestry Data Preparation

This project focuses on extracting, cleaning, and organizing ancestry data from a website. The data often contains misspellings and variations in names, making it difficult to process and analyze. By using data science techniques, I aim to resolve these issues and create a clean dataset for better analysis. This is a project in progress.

GenArtist Application (10/2024)

This project focuses on collecting and visualizing AI-generated images, generated with various artists to categorize them. It utilizes Supabase, an open-source alternative to Firebase for managing both database and storage. The project is deployed using Vercel, a platform designed for seamless deployment of web applications, similar to Google Cloud Run or AWS Amplify Hosting. FastAPI serves as the API backend, enabling efficient data fetching and integration with the Supabase database and storage. The combination of these tools ensures scalability, fast deployment, and easy management of data and images. This is a project in progress.
